CM67  
CHRONOTHERM  
PRODUCT SPECIFICATION SHEET  
The CM67 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).  
The CM67 is designed with the installer in mind and includes  
a moulded backplate with trunking guides and wiring  
breakouts to make installation quick and easy.  
The CM67 display, buttons and slider layout are based on  
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.  
FEATURES  
Attractive slim styling makes it ideal for location in  
Surface or wallbox mounting options, trunking  
any home.  
guides and wiring breakouts simplify installation.  
7-day program  
6 daily independent time and temperature level  
changes let you set 6 time and temperatures pairs to  
suit your life style.  
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 :

Day Off button copies Sunday’s program into  
tomorrow or today to allow a rest day program  
without having to re-program the CM67.  
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.

Telephone Interface (optional) can be fitted to the  
CM67 to allow switching between programmed mode  
(slider position) and fixed set-point of 21 oC.  
Outside Temperature Sensor accessory (optional)  
can be fitted to the CM67 to display the external  
temperature.  
24...230V 8A resistive, 3A inductive SPDT relay  
provides compatibility with most domestic central  
heating systems without stocking many different  
models.  
Remote Temperature Sensor (optional) can be fitted  
to the CM67 to control the temperature from another  
room.

Optimisation (Variable  
Start Time)  
Adaptive Intelligence  
recovery TM  
The Chronotherm will adjust the start time in the  
morning/ afternoon so the desired temperature is  
reached by the start of the program period e.g. Time  
7:00, Temp 21 oC. The Chronotherm will monitor the  
accuracy of the start up and use this information to  
modify the calculation for the following day by  
changing the ramp rate (initial 3 K/hr) .The system will  
restrict the start time to a max of 3 hours.  
Set parameter. 1 in the installer set-

Description  
What to do if we wish this  
feature  
Outside Temperature  
Sensor  
An Outside Temperature Sensor can be fitted to your  
CM67 to allow the homeowner to display the outside  
temperate on the Chronotherm display by using the  
INFO i button. CM67 will read the outside temperature  
every 10 minutes. Outside temperature display range is  
from -30 oC to +45 oC. The sensor can be connected up  
to 50 meters from the unit.  
1. Fit the sensor (instructions  
included in the sensor package)  
2. Set parameter n. 10 in the  
installer set-up mode to 1  
Remote Temperature  
Sensor  
A Remote Temperature Sensor can be fitted to your  
CM67 to allow the Chronotherm to control temperature  
from another room or space where it is inconvenient to  
locate the CM67 It will read the remote sensor every 1  
minute. The sensor can be connected up to 50 meters  
from the unit. Useful for commercial premises where  
the public may tamper with the product.  
1. Fit the sensor (instructions  
included in the sensor package)  
2. Set parameter n. 10 in the  
installer set-up mode to 2  
Automatic Time Setting  
(ATS) Module  
The ATS module picks up a time signal daily from a  
European transmitter, so you never need to set or  
adjust the time.  
1. Fit the ATS module  
2. Set parameter n. 4 in the installer  
set-up mode to 1

CM67 CHRONOTHERM  
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  
windows, 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
