Wireless control unit for controlling applications using OpenTherm communication . It allows more precise control of the boiler via a gas valve , which conducts heat from the boiler to the heating distribution. The unit transmits a valve signal that changes the supply of the amount of heat supplied by the boiler to the system.

Cooperation with the Honeywell Evohome multi-zone heating system is ensured . After receiving the 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 s unit is able to communicate with other devices supporting OpenTherm communication and RF communication . However, we recommend that you find out in advance what frequency or communication protocol the device has, because in case of a discrepancy, the unit will not communicate with the device.

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