If your phone or router is connected through a VPN, please disconnect and use your router’s ip address during the setup. The product will not complete the set-up if the phone or router is connected using a VPN service. This can be enabled once the pairing has been completed and will function correctly.
Some routers come with both 5GHz & 2.4GHz, with a single SSID set with a shared name. WiFi devices can connect with the 5GHz network if close to the router, or the 2.4GHz network if further away – 5GHz is faster but has a reduced range compared to 2.4GHz. Most routers will have a configuration set to use 5GHz as the preferred connection. If you try to connect to an Optimum WiFi device and can’t (the connect function goes full circle and then fails), your mobile may be connected to the 5GHz network.
You will need to go to the Admin page of the router. You may need to refer to the router documentation or contact your service provider for help with this. Separate the channels and rename the 2.4GHz/5GHz networks with different names i.e. add 2g or 5g to the end of each SSID respectively. Re-connect your phone to WiFi, selecting the re-named 2.4GHz network. You should now be able to set up the WiFi controls in the usual fashion.
Once the WiFi controls are set up in this way, control of WiFi devices is possible whether the mobile is connected to 5GHz or 2.4GHz. That’s because the input from your mobile is actually sending data to the server, which is then relaying the control commands or programming changes back to the WiFi device via your router, and because the WiFi router is dual-band, it can address those devices connected to either the 5GHz or 2.4GHz networks.
If this fails, please check your Firewall settings have no security features enabled to prevent new devices from connecting. You may need to refer to the router documentation or contact your service provider for help with this.
Check the Communication protocol: This should be set as “WPA2-PSK (AES)”. This is a setting you would need to check/edit on the Admin page of the router. You may need to refer to the router documentation or contact your service provider for help with this.

The firmware has been updated on this product and the sun symbol does not appear in manual operation. This was causing some confusion for some users and was removed. When you press the “SET” button to switch from the Programme mode to Manual you will see the “PRG” symbols disappear. Pressing the “SET” button repeatedly will step through the options:- Programme, Manual & Holiday modes.
Before running though the procedure of pairing, it is important to turn the power off to the boiler/receiver for at least 15 to 30 seconds. This puts the receiver into a mode whereby it transmits the code to pair-up to the thermostat (Transmitter). The main reason for the pairing to fail, is that the “POWER OFF” before going through the process has been missed.
The pairing sequence is…
1, Turn boiler / receiver off for 15 to 30 seconds.
2, Turn the power back on.
3, Touch bottom right corner of display on thermostat until display changes and you see “SET” appear bottom right and “01” appear bottom left and Release finger.
4, Touch the word “SET” (and release finger) and you will see “02” bottom left.
5,Touch the word “SET” (and release finger) you will see some numbers appear bottom left and big “00” in display.
6, Touch the numbers on bottom left of display (and release finger) and wait until you see “00” change to “AA”
7, Don’t touch anything and wait until display returns to normal, showing temperature etc.
The transmitter and receiver should now paired together.
You can manually reset the calibration by entering the configuration menu and adjusting the temperature offset value. To do this please follow the steps below.
1, Tap the bottom right hand corner of the display momentarily.
2, Touch and hold finger on bottom right hand corner of display until you see the word “set” appear (about 5 seconds after touching screen).
3, When you see “01” at the bottom left and a large number in the main display area, set the calibration value touching the left or right of the display. The default value should be -1 degree, but you may need to adjust up or down if not correct.
4, After setting offset value, press the bottom right “set” to move to configuration step “02”
5, Set this value to 0.5 by touching the left side of the display.
6, Wait approx. 10 seconds and the display will revert to normal and the displayed temperature should now be correct.
7, Reset your target temperature to your normal level.

No. The OP-TPISTAT is RF only and does not have Wi-Fi capability.
A thermostat or timer with ‘volt-free contacts’, or ‘volt-free switching’, operates a switch that opens and closes its contacts, but no voltage or current will flow. When a product has volt-free contacts, the installing electrician must ensure that the correct voltage (to be switched) is connected to the ‘common’ contact of the switch. This voltage, once connected to common, will then be fed to the circuit to be controlled, via the normally open contact. Wiring connected to the common contact must be suitably rated for the load current. The advantage of such an arrangement is that e.g. a mains-powered timer can switch a non-mains circuit, such as a low voltage alarm or lighting circuit.
You can set-up your Towerstat to operate manually. Please click on the link for a guide click here
The RF signal will pass through brick, glass and other standard building materials. Each obstacle will reduce the strength of the signal and in some instances could reduce it enough to block communications altogether. Please click on the link for a guide that shows typical losses. click here
For systems with an existing time control, set the heating to constant (fixed on). If there appears to be no communication between transmitter and receiver refer to the instruction on commissioning procedures.
If your thermostat is battery powered check that they have sufficient charge to operate your thermostat. If your thermostat is mains powered, check that the power is still present.
You have to select which day or days you want to programme. Select the day or days then enter the programme number you want.
Check that the setback (economy) temperature is set low enough. Overnight the temperature drops and if the ambient room temperature drops below the setback (economy) set-point, the heating will come on.
It is possible to use your existing programmer/timer to control the on/off periods. Set your Towerstat RF to “P1” and follow the wiring instruction at the following link click here
There are Radio Frequency (RF) thermostats available that can work over considerable distances and control the system without the need of wiring.
A thermostat that only requires two wires is usually connected to switch the live conductor. Live supply would connect to the common and switched live to N/O (normally open for heating systems) or N/C (normally closed for cooling systems). The neutral can be made safe and not used.
Most bi-metal thermostats require a neutral to complete the circuit that powers an accelerator heater and possibly an indicator lamp. Bi-metal thermostats require the accelerator heater to give a small differential and give consistent switching.
TPI (Time Proportional & Integral) control is a sophisticated algorithm used in heating systems for precise temperature regulation. It employs a control technique where the duration and frequency of the heating cycles are modulated to maintain the target temperature as closely as possible without large fluctuations.
Here’s how it works technically: TPI divides each cycle into smaller intervals. It calculates the difference between the actual and desired temperatures and adjusts the heating accordingly. If the temperature is too low, it increases the “on” time; if too high, it decreases it.
The ‘Integral’ aspect means it also considers the cumulative error over time, not just the immediate difference. This helps to eliminate the residual error, preventing the temperature from settling above or below the setpoint after initial adjustments.
For example, in a heating system, if the target temperature is 20°C, TPI may start with longer “on” periods to heat up quickly. As the temperature approaches 20°C, it shortens the “on” periods and may even fine-tune the “off” periods to avoid overshooting the target. Over time, it uses the integral calculation to fine-tune further, ensuring the room stays at a stable 20°C with minimal fluctuations.
TPI control is more precise than traditional two-point (on/off) control because it adjusts the heating cycle’s duration based on the temperature’s deviation from the setpoint. It minimizes overshoot and undershoot by accounting for the thermal characteristics of the space being heated. This results in a more consistent temperature and can be more energy-efficient since it reduces the frequency of large temperature swings that require more energy to correct. In essence, TPI provides a smoother approach to reaching and maintaining the desired temperature.
Two-point control, also known as on-off control, has several disadvantages:
Temperature Variability: It can lead to significant temperature fluctuations above and below the setpoint, as the system only turns on or off at certain thresholds.
Inefficiency: These fluctuations can lead to inefficiency in energy use because the system might overheat or cool, then need to correct itself.
Wear and Tear: The frequent cycling on and off can cause increased wear and tear on mechanical components, reducing their lifespan.
Lack of Fine Tuning: It lacks the ability to finely tune the output to the exact needs of the space, which can result in discomfort and wasted energy.
Timers & Programmers
The TS1 timeswitch is a device that enables users to program up to 3 periods per day for automatic on and off functionality. To set up the timeswitch to turn on in the morning and turn off in the evening, the user needs to program the three periods with the desired on and off times. For example, P1 can be programmed to turn on at 6:30 am and turn off at 9:00 am, P2 can be programmed to turn on at 12:00 pm and turn off at 1:00 pm, and P3 can be programmed to turn on at 5:00 pm and turn off at 10:30 pm.
Once the desired on and off times have been programmed, the user can return the device to normal running mode and select the “Once” option by pressing the “Mode” button. With each press, the “Mode” button will cycle through available options until “ONCE” appears. Selecting the “ONCE” option will instruct the timer to only take note of the first “On” instruction and the last “Off” instruction, ignoring all other instructions. This allows the user to ensure that the device will turn on at the desired time in the morning and turn off at the desired time in the evening, regardless of any other programmed periods.

The main reason a digital programmer will appear to reset or suffer program corruption is a surge/spike in the mains supply or from the load itself. If you suffer power cuts or see your lights dim or brighten, your power supply is fluctuating. If your programmer is connected to a control circuit via a contactor or relay you could be suffering from “Back EMF”. To overcome both of these situations please refer to our suggested suppression techniques click here
Check that the override has not been set to “Fixed off” or the thermostat set too low.
Check that the override has not been set to “Fixed on”.
All of the digital timers that have a built in battery backup can be programmed and settings changed etc. whilst running on the battery. The full display and switching of outputs can only be achieved once the power supply has been connected.
You will need to set your timer to the current time by aligning the outer dial with the arrow marker on the face of the timer. You then move the tappets outward between the times you want the timer to be on. Please see the PDF for a more detailed explanation click here
LED lighting has a transformer that uses power factor correction on the start-up circuit. This can cause an inrush current that is hundreds of times higher than the running current and overloads the contacts. Although this may only exist for 5 or 10 milliseconds, it is enough time to tack weld the output contacts. If you have this problem you will need to switch the lighting circuit with a contactor.

The Perry 1IO7080 is often used for break time sounders and the output can be set down to a 1-second output if required. This type of output is generally referred to as “Pulse Output” and is a standard feature on the Perry Din Rail timer.
Understanding NiMH Battery Degradation: Causes and Prevention
In today’s tech-driven world, batteries are the unsung heroes that power our devices. Among the various types of batteries available, Nickel-Metal Hydride (NiMH) batteries have carved a niche for themselves due to their rechargeable nature and high capacity. However, like all good things, NiMH batteries are not immune to the ravages of time. When left in a discharged state for extended periods, these batteries can experience degradation, leading to reduced performance and lifespan.
So, what causes NiMH batteries to degrade over time, and how can we prevent it? In this article, we’ll delve into the intricacies of NiMH battery deterioration, exploring the chemical processes at play and offering tips on how to keep your batteries performing at their best.
Self-Discharge: The Silent Culprit
One of the primary reasons behind NiMH battery degradation is a phenomenon known as self-discharge. Even when not in use, NiMH batteries gradually lose their charge over time. This loss can be attributed to the internal chemical reactions taking place within the battery, albeit at a slow rate. On average, NiMH batteries experience a self-discharge rate of about 0.2% to 0.3% per day. While this may seem inconsequential in the short term, it can add up significantly if the battery remains unused for an extended period.
The “Sleep” State Conundrum
NiMH batteries take a different approach when they’re not used for several months. They enter a state often referred to as “sleep.” During this slumber, their ability to hold a charge undergoes a significant reduction. This means that when you eventually try to wake them from their hibernation for that important device or gadget, they might not have the power you’d expect.
Peeling Back the Layers: Understanding the Chemistry
Now, let’s get a bit technical. The degradation of NiMH batteries when left discharged involves complex chemical processes within the battery. These processes can include the crystallization of electrolytes and the degradation of electrodes, among other things. Over time, these changes within the battery can manifest as a reduced capacity to accept a charge and deliver power.
While the precise chemical reactions at play are intricate, the practical implications are clear: a decreased ability to hold and deliver power effectively. This ultimately leads to a shorter lifespan and diminished performance for your NiMH batteries.
Preventing NiMH Battery Degradation: Best Practices
The good news is that while NiMH battery degradation is an inevitability, there are steps you can take to slow down the process and prolong the life of your batteries:
1. Regular Recharging: Make it a habit to recharge your NiMH batteries, even if they haven’t been used for a while. This prevents deep discharge, which can accelerate degradation.
2. Storage Conditions: Store your batteries in a cool, dry place away from direct sunlight. Extreme temperatures and humidity can exacerbate self-discharge and the “sleep” state.
3. Battery Management Systems (BMS): Consider using NiMH batteries with built-in Battery Management Systems, which can help maintain the batteries in good condition by preventing overcharging or deep discharging.
4. Rotate Batteries: If you have multiple sets of NiMH batteries, rotate them regularly to ensure all batteries get used and recharged periodically.
5. Check the Manufacturer’s Guidelines: Always follow the manufacturer’s recommendations regarding storage, charging, and usage of NiMH batteries.
In conclusion, NiMH batteries are reliable and versatile energy sources, but they require proper care to maintain their performance over time. Understanding the causes of their degradation and taking appropriate preventive measures can significantly extend their lifespan. As we continue to rely on batteries for our daily lives, a little care and attention can go a long way in ensuring these energy workhorses keep powering our devices efficiently.
Valves and TRVs
To completely shut off your TRV, avoid using the thermostatic head for this purpose. Instead, follow these steps:
-
Remove the TRV head.
-
Locate the “Decorators Cap” that comes with the TRV.
-
Screw the “Decorators Cap” fully onto the TRV body. This action will lock the pin down and effectively close the valve.
By using the “Decorators Cap” in this manner, you can ensure that your TRV is completely shut off.
The central heating synchronous valve motor is an important component in heating systems, used in both mid-position 3-Port valves and 2-port zone valves, to control the flow of hot water or heating fluid. Let’s explore its function in each valve type.
3-Port Mid Position Valves:
In a mid-position valve, the synchronous valve motor serves a crucial function in three different states:
Closed Heating Circuit (Default State): When there is no demand for heating or hot water, the synchronous valve motor keeps the valve in a closed position, ensuring that the heating circuit remains closed to conserve energy.
Mid-Position State: When there is a simultaneous demand for both heating and hot water, the synchronous valve motor moves the valve to the mid-position. This allows the flow of hot water or heating fluid to both the heating system and the hot water system simultaneously, enabling both functions to operate together effectively.
Heating Only State: When there is a demand for heating but not hot water, the synchronous valve motor moves the valve to a specific position that directs the flow of hot water or heating fluid to the heating system only. This ensures dedicated heating control without diverting hot water to unnecessary areas.
2-Port Zone Valves:
In a 2-port zone valve, the synchronous valve motor is utilized primarily to open the valve. The valve itself is equipped with a spring return mechanism that automatically closes the valve when the motor is not actively powered.
When a signal is received from the thermostat or central heating control system, the synchronous valve motor is activated to open the valve, allowing the flow of hot water or heating fluid to a specific zone or area of the heating system. This enables individual control and zoning of different heating zones.
Once the motor receives the signal and opens the valve, it remains powered to keep the valve in the open position. However, when the signal is no longer present, the synchronous valve motor is deactivated, and the spring return mechanism takes over. The spring returns the valve to its default closed position, shutting off the flow of hot water or heating fluid to the designated zone.
By utilizing the motor to open the valve and relying on the spring return to close it, the 2-port zone valve allows for efficient and reliable control of the heating system. The motor ensures precise opening of the valve to direct the flow, while the spring return mechanism provides a fail-safe mechanism for automatic closure when the motor is not actively powered.
To summarize, in a 2-port zone valve, the synchronous valve motor is responsible for opening the valve, allowing the flow of hot water or heating fluid to a specific zone. The valve incorporates a spring return mechanism to automatically close the valve when the motor is not actively powered, ensuring reliable operation and control of the heating system.
In both mid-position valves and 2-port zone valves, one of the conveniences is the ability to replace the valve motor without the need to drain the entire heating system. This feature offers several advantages:
Time and Effort Saving: When a valve motor needs replacement, not having to drain the entire system saves significant time and effort. Draining a heating system can be a time-consuming and complex task, requiring careful steps to avoid damage or airlocks. By eliminating the need for system draining, the process of replacing the valve motor becomes much simpler and quicker.
Cost-Effective Solution: Draining a heating system may require professional assistance, which can add to the overall cost. By removing the necessity of system drainage, the expense of hiring professionals or investing in specialized equipment for draining can be avoided, resulting in cost savings.
Minimized Disruption: Draining a heating system disrupts the functioning of the system, requiring it to be shut down temporarily. This can lead to discomfort and inconvenience, particularly during colder seasons when heating is essential. With the ability to replace the valve motor without draining the system, the disruption to the heating system’s operation is minimized, ensuring continued comfort for occupants.
Simplified Maintenance: The option to replace the valve motor without draining the system simplifies routine maintenance tasks. Whether in mid-position valves or 2-port zone valves, if motor replacement is required as part of regular servicing or troubleshooting, it can be easily done without interrupting the entire heating system’s functionality, making maintenance procedures more efficient.
Overall, the convenience of being able to replace the valve motor in both mid-position valves and 2-port zone valves without draining the heating system saves time, effort, and cost. It minimizes disruption to the system’s operation, allows for more efficient maintenance, and ensures uninterrupted heating comfort for occupants.
RPM explained:
When it comes to control and added torque, a lower rotational speed of 4 RPM (Rotations Per Minute) can often be preferred over higher speeds like 5 or 6 RPM. The slower speed allows for finer and more precise control over the movement of the mechanism or device. It provides a smoother operation and reduces the risk of overshooting or inaccurate positioning. Additionally, a lower RPM can offer increased torque, which is beneficial in applications that require higher rotational force or when dealing with heavier loads. The added torque ensures the motor has the necessary power to handle the required tasks effectively and reliably. Therefore, opting for 4 RPM can provide improved control and enhanced torque, resulting in better performance and accuracy in various applications.

The grey wire must be connected to the cylinder satisfied and then to the programmers “hot water off” terminal. This provides 230V AC to the grey wire when the hot water is satisfied or not in demand. Without the grey wire connected in this way, when calling for heating only the valve will open until it reaches the mid position. Power on the grey will allow it to travel fully and energize the boiler and pump.
Check the flow direction. There is an arrow on the body of the valve to show the correct orientation.
No, the valve will remain in that state until power is removed or hot water is called for. The synchronous motor is rated for running in a continuously stalled state.
The valve will feel hot to the touch, as the energy of the stalled motor is dissipated through the valve body. This is normal and the valve is designed to operate in this way.
To avoid this happening…. Set the Hot water to go into demand after the heating has switched off.
This is to ensure that should a leak occur that water does not come into contact with the internal electrical components.
Yes, the “VAL322MP & VAL222MV” Tower valve actuators can be replaced independently of the valve. This is the same process for both valves click here
Once you have added your zone valve you will need to wire it in parallel to your existing heating control valve. If you have an S-Plan system (2 x 2 Ports) click here
Once you have added your zone valve you will need to wire it in parallel to your existing heating control valve. If you have a Y-Plan system (Mid position) click here
Yes, you will need to add a changeover relay to make the VAL228MV work in the same way. Please download the schematic showing how to connect a relay click here
Yes, join the white and grey wires together and supply them with 230V AC to spool the valve open. The default port that is closed is port “A”. When power is supplied to white and grey the valve will motor until port “B” has closed. Remove power and the valve will return to Port “A” being closed and port “B” open.
