CM701 (UK Version)
PROGRAMMABLE THERMOSTAT
PRODUCT SPECIFICATION SHEET
The CM701 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 CM701 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 CM701 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.
