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°C. The system will restrict the start time to a max of 3 hours
The end user can have a different clock format display
The circulating pump on hydronic systems can be exercised once a day for 1
minute at mid-day. Useful to prevent the pump from sticking after the summer
The normal upper temperature limit of 30°C can be reduced down to 21°C to
save the homeowner energy.
The normal lower temperature limit of 5°C can be increased up to 16°C to
protect the inhabitants from cold. Useful if the inhabitants include the elderly,
children or disabled
If the Chronotherm is located in a particularly 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
Can be adjusted up to 3°C (default is 1.5°C) to provide better temperature
control (less overshoot). Useful for:
a.  Well insulated homes with over-sized heating systems
b.  Air systems with fast response

by using the INFO 
 button.
A Remote Temperature Sensor can be fitted to your CM67 to allow the
Chronotherm to control the temperature from another room e.g. in a
commercial premises where the public may adjust keys.
The ATS module picks up a time signal daily from a European transmitter, so
you never need to set or adjust the time.
Move the slider to
the OFF position.
