The CM927 Wireless RF Programmable Thermostat is designed to provide wireless time and temperature control to heating or cooling systems in domestic and light commercial buildings.
The slim, ultra modern design complements the large LCD screen with the Line of Text display and one function button to ensure simplified programming and operation for all users.
The CM927 can be used to control the heating circuit in a Sundial S or Y Plan and is particularly well suited to control combination boiler installations or additional zones in a S Plan Plus system.
CM927 can provide a different heating programme for each day of the week to maximise energy efficiency.
Two wire, volt free connections are ideal for use with combination boilers.
