Wireless control unit for managing applications using OpenTherm communication. It allows for more precise control of the boiler via the gas valve, which directs heat from the boiler into the heating circuit. The unit transmits a signal to the valve, which adjusts the amount of heat supplied by the boiler to the system.

Collaboration with the Honeywell Evohome multi-zone heating system is ensured. Upon receiving a signal from the Evohome device, the unit converts it into the OpenTherm communication protocol and sends it to the end device. In addition to the Evohome system, the R8810A1018 unit is capable of communicating with other devices supporting OpenTherm communication and RF communication. However, we recommend checking in advance what frequency or communication protocol the given device uses, as the unit will not communicate with the device in case of a mismatch.

Compatible devices from Honeywell: T87RF, CMS927, CMS921, DTS92E, RF2 Pack 3, Evohome control units.
