DIMENSIONS
INSTALLATION
LOCATIONThe CM701 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 meters above the floor level. Do not position the CM701 thermostat near sources of heat (radiators, hot-air vents, TV or lights), near doors or windows, or indirect sunlight.MOUNTINGThe CM701 thermostat can be mounted directly on the wall surface or onto an electrical wall box.WIRING The CM701 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 a 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
