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 combiboilers, 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.

Adaptive Intelligence recovery TM | reached by the start of the program period e.g. Time 7:00, Temp 21 oC. The thermostat will monitor the accuracy of the start up and use this information to | |
modify the calculation for the following day by changing | ||
the ramp rate (initial 3 K/hr) .The system will restrict the | ||
start time to a max of 2 hours. | ||
Note: Optimisation will not work in cooling mode. | ||
AM-PM/ 24hr Display | Change display format (default 24hr). | Set parameter n.1, category 1 in the installer set -up mode to 12. |
Pump exercise | When enabled the Pump Exercise will switch the relay on for 1 minute at 12:00 if the relay has not been switched on since 12:00 the previous day.While in Holiday mode the Pump Exercise feature, if enabled, will operate. | Set parameter n.5, category 2 in the installer set -up mode to 1. |
Upper Temperature Limit | The normal upper-temperature limit of 35 oC can be reduced down to 21 oC to save the homeowner energy. Useful if the homeowner rents to tenants. | Set parameter n.6, category 1 in the installer set -up mode to the desired limit. |
Lower Temperature Limit | The normal lower temperature limit of 5 oC can be increased up to 21 oC to protect the inhabitants from cold. Useful if the inhabitants include the elderly, children or disabled. | Set parameter n.7, category 1 in the installer set -up mode to the desired limit. |
Temperature Offset | If the thermostat is located in a hot/cold location and cannot be moved because of wiring then the measured/ displayed temperature can be adjusted by +/- 3 oC. Useful if the homeowner wants the reading to match another appliance temperature display. | Set parameter n.12, category 1 in the installer set -up mode to the desired offset value. |
Proportional Band Width | Can be adjusted up to 3 oC (default is 1.5 oC) to provide better temperature control (less overshoot).Useful for: a. Well insulated homes with over-sized heating systems. b. Air systems with fast response. | Set parameter n.13, category 1 in the installer set -up mode to the desired value. |
Optional Accessories | Description | What to do if we wish this feature |
Outside Temperature Sensor (F42010971 001) | An Outside Temperature Sensor can be fitted, allowing the homeowner to display the outside temperate on thethermostat display by pressing the INFO i button. The thermostat will read the outside temperature every 10 minutes. Outside temperature display range is from -30 oC to +45 oC. The sensor can be connected up to 50 meters from the unit. | 1. Fit the sensor (instructions included in the sensor package).2. Set parameter n. 10, category 1 in the installer set-up mode to 1. |
Remote Temperature Sensor (F42010972 001) | A Remote Temperature Sensor can be fitted, allowing the thermostat to control the temperature from another room or space where it is inconvenient to locate the thermostat. It will read the remote sensor every 1 minute. The sensor can be connected up to 50 meters from the unit. Useful for commercial premises where the public may tamper with the product. | 1. Fit the sensor (instructions included in the sensor package).2. Set parameter n. 10, category 1 in the installer set-up mode to 2. |

The CM901 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 CM901 thermostat near sources of heat (radiators, hot air vents, TV or lights), near doors or windows, or in direct sunlight.
MOUNTING
The CM901 thermostat can be mounted directly on the wall surface or on an electrical wall-box.
WIRING
The CM901 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).
