PRODUCT SPECIFICATION SHEET
The CM907 thermostat is designed to provide automatic time and temperature control of heating or cooling systems in villas and apartments.It can be used as part of a system in conjunction with combi- boilers, oil-burners and gas fired boilers, circulation pumps, thermal actuators, zone valves and electric heat systems (<8A).The CM907 is designed with the installer in mind and includes a moulded back-plate with trunking guides and wiring breakouts to make installation quick and easy.The CM907 extra large LCD display, dynamic text display, button layout based on the same simple programming philosophy used on our acclaimed CM60 products and the introduction of an ‘OK’ button, makes it easier to install and more user friendly.The unit is ideal for consumers who want reliable precise temperature control from a modern looking, simple to program and easy to use product.
- Built-in default heating
- Automatic Summer / Winter time change adjusts the time automatically to daylight saving time.
- Telephone interface can be fitted to allow remote switching between program modes and a fixed set-point.
- Surface or wall-box mounting options with trunking guides and wiring breakouts to simplify
- No installer links or special installer switches on the back of the unit mean no adjustment is required for combi-boilers and most domestic central heating
- User Set-Up Mode allows extra functions to be set at the discretion of the user:
- AM-PM or 24hr time display.
- Resetting the heating profile to factory
- Enable / disable of Auto Summer / Winter time
- Languages selection of the user interface (on selected models only).

DIMENSIONS
INSTALLATION
LOCATION
The CM907 thermostat is the control element of the heating / cooling system and, therefore, MUST be located in a position with good air circulation, at average room temperature and on an inside wall 1.5 metres, above the floor level. Do not position the CM907 thermostat near sources of heat (radiators, hot air vents, TV or lights), near doors or windows, or in direct sunlight.
MOUNTING
The CM907 thermostat can be mounted directly on the wall surface or on an electrical wallbox.
WIRING
The CM907 thermostat is designed for fixed wiring only and must be installed in accordance with the latest l.E.E. regulations. Ensure the wiring connection to the supply is via a fuse rated at no more than 8 amps and a Class “A” switch (having contact separation of at least 3 mm in all poles).
IMPORTANT
- The installer must be a trained service engineer
- Disconnect the power supply before beginning installation
