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 6.). 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.
The adjusted values (while programming) will be accepted automatically after ~5 sec.
2. Automatic mode (AUTO)
In this mode, the room temperature is automatically controlled according to the pre-
set program. The pointer indicating the mode is set to AUTO. The number at the bot-
tom right indicates the program event during the day. (Fig. 1)
3. How to change the temperature for a short period of time
(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
to the AUTO mode.
4. How to set a constant room temperature (manual operation)
In this mode, a constant temperature can be set and the pre-set program is ignored.
The temperature last selected is chosen as the initial temperature.
How to activate this mode
Press the < button until the pointer indicates MAN (Fig. 3).
Set the temperature by pressing the +- button
Exit the mode
by pressing the > button
5. 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
