Boiler Module or Immersion
& General Purpose Timer

OP-BM-IHTWF01 is a WiFi Universal Boiler Module or Immersion Heater Control. Remotely programmable via the user’s home WiFi hub and a smartphone app. Via the App it can be programmed for a timed switching sequence on a 24 hour or 7 day basis. It controls a volt-free switch with a resistive rating of 16 amperes.

The WiFi Module can be easily removed from the enclosure and directly mounted inside boilers with suitable timer apertures.

There is a manual override button on the device and it can be manually overridden via the app, whether the user is in wifi range, or remotely if the smartphone has a data signal.

Additional WiFi switches can be added to the system – a standard WiFi router has capacity for up to 15 devices. Devices can be grouped, and work with either Amazon Alexa or google home. Security is military grade A.E.S. encryption, with dynamic key allocation and an https encrypted channel.
