Configuration and calibration of the IRT 30 thermostat
Calibration of the temperature sensor of the thermostat
The temperature sensor in the IRT 30 thermostat should be
calibrated when the measured temperature, shown on the display,
deviates from the actual temperature.
It is no simple task to determine the actual temperature in
the room.The position you are measuring and the accuracy of
the thermometer you are using may influence the result. It is
also important to measure the temperature when the tempe-
rature is stable, (i.e. not during the heat-up periods etc.).
You can recalibrate the temperature sensor as follows:
1. Make sure the display is in normal mode (refer to figure 3-2).
2. Press and hold the MENU and then REMOVE key. Hold both
keys. In the middle of the display, the temperature which is
measured by the sensor in the thermostat is shown. On the
right side, a blinking temperature, which you can alter, is
shown.
3. Turn the program knob, while holding the MENU and
REMOVE keys, until the blinking temperature indicates the
actual temperature.
4. Release all keys when you are finished.
Calibration of the temperature adjustment knob
Calibration of the temperature adjustment knob of the
thermostat may be necessary when the actual temperature
deviates from the temperature which is set manually with the
temperature adjustment knob. For example, the temperature
adjustment knob is set to 20 °C but in the long term the actual
temperature never rises above 19 °C.
You can calibrate the temperature adjustment knob as follows:
1. Make sure the display is in normal mode (refer to figure 3-2).
2. Simultaneously press the MENU and REMOVE keys twice and
hold them.To the right on the display, the TEMP symbol appears.
