CM707
PROGRAMMABLE THERMOSTAT
PRODUCT SPECIFICATION SHEET
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 combi-
boilers, 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.
FEATURES
•Attractive slim, modern styling makes it ideal for
location in any type of home.
•7 day heating program.
•Up to 4 daily independent time and temperature level
changes let you set 4 time and temperatures pairs to
suit your lifestyle.
•Temporary programmed temperature override to
temporarily override the programmed temperature till
the next switch point.
•Holiday button provides energy savings by
reducing the temperature from 1 to 99 days when
people are on holiday, returning to normal operation
(AUTO or MANUAL) on the day of their return.
•Room Temperature Enquiry.
•EEPROM memory holds the user program
indefinitely.
•OFF mode has an integral frost protection setting at
minimum 5°C (installer adjustable) so that pipes in
the house will never freeze in winter.

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:

DIMENSIONS
LOCATION
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.
MOUNTING
The CM707 thermostat can be mounted directly on the wall
surface or on to an electrical wall box.
WIRING
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).
IMPORTANT
1. The installer must be a trained service engineer.
2. Disconnect the power supply before beginning
installation.
