The CM707 thermostat is designed to provide automatic time and temperature control of heating 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 (<5A).
The CM707 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 CM707 large LCD display, button layout based on the same simple programming philosophy used on our acclaimed CM20 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.
Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the consumers applications and needs:
Diagnostic Mode to assist in fault finding.

Special Features | Description | What to do if we wish this feature |
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:
| Set parameter n.13, category 1 in the installer set -up mode to the desired value. |

The CM707 thermostat is the control element of the heating 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 CM707 thermostat near sources of heat (radiators, hot air vents, TV or lights), near doors or windows, or in direct sunlight.
The CM707 thermostat can be mounted directly on the wall surface or on to an electrical wall box.
The CM707 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 5 amps and a Class "A" switch (having contact separation of at least 3 mm in all poles).
