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 combi boilers, 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 molded 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 the product.
FEATURES
- Attractive slim, modern styling makes it ideal for location in any type of home.
- 24-hour 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.
- Room Temperature Enquiry.
- EEPROM memory holds the user program indefinitely.
- The OFF mode has an integral frost protection setting at a minimum 5°C (installer adjustable) so that pipes in the house will never freeze in winter.
- 24…230V 5A resistive, 2A inductive SPDT relay provides compatibility with most domestic central heating systems reducing the need to stock many different models.
- Battery-powered by 2 x AA size (LR6) alkaline cells.
- Minimum battery life of 2 years with low battery warning indicator.
- Built-in default heating program.
- Surface or wall box mounting options, with trunking guides and wiring breakouts to simplify installation.
- No installer links or special installer switches on the back of the unit mean no adjustment is required for combi boilers and most domestic central heating systems.
- User Set-Up Mode allows extra functions to be set at the discretion of the user:
- AM-PM or 24hr time display.
- Resetting the heating profile to factory default.
- Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the consumer’s applications and needs:
- Pump Exercise.
- Upper / Lower Setpoint Limit Adjust.
- Temperature offset.
- Minimum ON time.
- Cycle rate.
- Proportional Band Width.

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°C can be
increased up to 21 °C 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°C. 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°C (default is 1.5 °C) to
provide better temperature control (less overshoot).

DIMENSIONS
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 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.
MOUNTING
The 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
