Operation (Overview)

1. Principle of function

INSTAT+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.
