The HR92 radiator controller uses two-way communication with the evohome controller to ensure that commands are received and valves opened while maintaining boiler interlock.
These slim, ergonomically-designed radiator controllers will fit on most standard TRV bodies. They are battery powered with a two-year battery life and a battery low reminder visible on both the radiator controller screen and the evohome controller screen. The flip-up screen is backlit and can be positioned so that it can be easily viewed or folded away flat.
The backlit LCD screen displays the zone name, and local set point temperature. The local set point temperature can easily be overridden by turning the dial at the top of the radiator controller. Override temperatures can be set in half degree increments and are effective until the next scheduled temperature change. There is an open window feature that recognises sudden temperature drop and shuts off the local radiator.
The zone temperature changes made at either the evohome controller’s screen or via the remote app will change in real time on the screen on the radiator controller.
Radiator controllers provide the optimum solution for installers when considering installing heating zones as there are no additional zone valves required which makes installation a lot quicker and cleaner. With existing TRV bodies already in place there is no need to drain down the system and they will fit on most compact radiators.
They are easily bound into the system using the guided configuration feature in the evohome controller; binding confirmation is displayed on the screen. Controllers are also available individually.
