Description

The OP-2PORTH is a 2 Port spring return valve actuator that fits the 22mm & 28mm Optimum zone valves. This is for general purpose flow control applications or central heating systems. When correctly wired with an appropriate room thermostat, cylinder thermostat and programmer the valve will control the water from the boiler to hot water and from the boiler to central heating. Supplied with protective plastic covering on the actuator to avoid scratches during shipping/installation and is easily removed once the installation is complete.

Installation:
When replacing the valve actuator, set the Auto/Manual lever to the “Manual Open” position before removal. On the replacement actuator set the Auto/Manual lever to “Manual Open” position before fitting. All controls must be earthed. All valves should have a means of disconnection from the electrical mains supply which incorporates a contact separation of at least 3mm in all poles. All wiring should be carried out to IEE Regulations

Wiring:
Green & Yellow – Earth
Brown
– Live (from thermostat demand)
Blue – Neutral
Grey – End switch in
Orange – End switch out

The valve must be powered by 230V AC connected through the thermostat to “Brown” on the valve. You may switch any voltage from zero to 240V AC. The voltage that is connected to grey will switch out to orange when the valve has opened. This allows you to operate the valve on 230V whilst switching a lower voltage output to the system if required.
