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.
INSTAT+2R7, -3R7 is a 7 day or 5:2 day Programmable RoomThermostat. Allowing dif-
ferent programs for weekdays and weekends and also every day of the week can be
programmed differently.
NOTE:
The adjusted values (while programming) will be accepted automatically after ~5 sec.

(override)
When in AUTO mode, you can override the existing temperature setting for a short
period of time.
Press the + or – buttons to change the temperature setting.
While in temperature override the pointer indicates both AUTO and MAN (Fig. 2).
When the next programmed time/temperature event is reached, the device will revert

6. How to set the room temperature for a set time
(holiday/party mode)
In this mode, the temperature can be set for periods of time ranging from a few hours
up to 199 days, e.g. when you are away from home for longer periods of time (holi-
days).
The remaining hours/days are shown. Time periods between 1 hour and 23 hours and
1 day and 199 days can be set.
How to activate this mode

troller. Pre-set program 1 (as shown below) is the default. Therefore, if pre-set pro-
gram 1 is the best program to suit your lifestyle, you do not need to change the
time/temperature settings on the device.
