Operation (Overview)
1. Principle of function
INST AT

the programmable room thermostat allows you to set time periods (up to 6
per day) and temperatures to suit your own lifestyle. Once fully installed and powered
the device will automatically set the correct time and in auto mode will control your
heating system according to pre-set program 1 (see 7.). The temperature is controlled
by sensing air temperature, switching on the heating when the air temperature falls
below the thermostat setting and switching it off once this set temperature has been
reached.
NOTE:
The adjusted values (while programming) will be accepted automatically after ~5 sec.
