Temperature sensors of heating profile
Preparation The safe operation of the unit depends on the
accuracy of the temperature sensors.
The 2 sensors can be tested by a comparison of
the sensor temperatures with the room
temperature. This is possible when the profile is
cooled down to room temperature (20
– 26°). All
measurements can only be carried out when the
room has a uniform temperature and when the
profile is hanging like described below.
The heating profile must hang concentric and the
thermometer for the room temperature must hang
like shown in the picture. The room temperature
sensor must be 70 cm away from the turning point.
This preparation ensures that the sensors in the
heating profile cool down quickly to room
temperature. After that the measurements can be
carried out.
Uneven temperature distribution because of opened windows or
doors, incoming sunrays or other heat sources like heater fans
disable this measurement.
If the test is prepared as described, the measurement can be
carried out after about 30 minutes.
Required
Actions
Proper operation of the temperature sensors of the heating profile
is verified through the following steps:
1. The heating profile and the room thermometer must hang as
described above.
2. Connect the heating profile to the connection cable of the
control unit.
3.
Press the “Standby” button
(
On Mode
).
4.
Press the “Test” button
continuously for at least 2
seconds.
The display shows the temperature of the first
temperature sensor and the LED “Start” turns off.
5.
Press the “Set” button
.
The display shows the temperature of the second
temperature sensor.
Each time the "Set” button
is pressed, the
temperature of the other temperature sensor is displayed.
6. Measure the room temperature at the specified position.
