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.

DIMENSIONS
CM701 CHRONOTHERM
INSTALLATION
LOCATION
The 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 metres 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 in direct
sunlight.
MOUNTING
The CM701 thermostat can be mounted directly on the wall
surface or on to 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 contact separation of at least 3 mm in all poles).
IMPORTANT
1. The installer must be a trained service engineer
2. Disconnect the power supply before beginning
installation
