7 Chronotherm is designed to provide automatic
time and temperature control of heating or cooling 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 (<8A).
CM67 is designed with the installer in mind and includes
The
a moulded backplate with trunking guides and wiring
breakouts to make installation quick and easy.
CM67 display, buttons and slider layout are based on
The
the same simple programming philosophy used on the
acclaimed CM51 product. The unit is ideal for consumers
who want reliable precise temperature control from a simple
to program easy to use product.
• Attractive slim styling makes it ideal for location in
any home.
• 7-day program
• 6 daily independent time and temperature level
changes let you set 6 time and temperatures pairs to
suit your life style.
• Temporary programmed temperature override to
temporarily override the programmed temperature
till the next switch point.
• Party button to temporarily maintain (or adjust)
the current temperature for 1-23 hours.
• Day Off button copies Sunday’s program into
tomorrow or today to allow a rest day program
without having to re-program the CM
67.
• Holiday button provides energy savings by
reducing the temperature for 1 to 99 days when
people are on holiday, returning to normal operation
(AUTO or MANUAL) on the day of return.
• EEPROM memory holds the user program
indefinitely.
• Telephone Interface (optional) can be fitted to the
67 to allow switching between programmed mode

provides compatibility with most domestic central
heating systems without stocking many different

•
urface or wallbox mounting options, trunking
guides and wiring breakouts simplify installation.
• OFF position on the slider has an integral fixed frost
protection setting at minimum of 5°°°°C (installer
adjustable) so that pipes in the house will never
freeze in winter.
• Installer Set-Up Mode allows extra functions to be
set at the discretion of the installer to match the
consumers applications :
• Optimisation
• Pump Exercise
• Upper / Lower Setpoint Limit Adjust
• Temperature offset
• Minimum ON time
• Cycle rate

DIMENSIONS
INSTALLATION
LOCATION
The CM67 Chronotherm is the temperature control element
in the heating/cooling system and MUST be located in a
position with good air circulation at average room
temperature on an inside wall 1.5 metres above the floor
level. Do not position the CM67 Chronotherm near sources
of heat (radiators, hot air vents, TV or lights), near doors or
indows, or in direct sunlight.
MOUNTING
The CM67 Chronotherm can be mounted directly on the wall
surface or on an electrical wallbox.
WIRING
The CM67 Chronotherm is designed for fixed wiring only and
must be installed in accordance with latest l.E.E. regulations.
Ensure the wiring connection to the supply is via a fuse rated
at no more than 8 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
