Honeywell HR91 Radiator Controller

The HR91 TRV's work directly with the Lightwave Link Plus which is required to control these devices. Devices can be controlled via the Lightwave app or with voice control. The EvoHome hub is not required.

The HR91 is a wireless radiator controller for use as part of the evohome multi-zoning heating control system.

 It has a non-intrusive design that will suit areas of high footfall or when the evohome radiator controller will not be visible during normal operations. It sits alongside the HR92 radiator controller in the range of evohome products.

 The HR91 enhances the evohome system offering since it strengthens the suitability of the evohome system for light commercial applications as temperature override at the installation point is restricted.

 The radiator controller: As the primary temperature sensor in an evohome zoning system, the evohome radiator controller uses two-way communication with the evohome controller to ensure that temperature information and commands are sent and received and valves opened while maintaining boiler interlock.

 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
