When operated, the electronic measures the temperature of the indoor air
sensor (NTC) and controls depending on this, the heating efficiency of the
absorber with the help of the HiPro-Electronic .
Self-test of the electronics
After switching on the supply voltage (Hardware- Reset) the software
carries out a selftest, in which the value of resistance of the NTC-sensors
(air-sensor, evaporator sensor) are measured.
In case the value of the resistance measuring is not corresponding
to the values of resistance fixed by the software, an error is
signalized.
Automatic fault analysis
The type of error is signalised through n flashing impulses of the inner
lighting (P_LIGHT) as well as REDDOT_LED with a frequency of 0.5 Hz, as
shown in the following table:
Type of error
Number of flashing impulses
general error electronic, power supply
n = 0
everything OK / no poti connected
n = 1
everything OK / poti connected
n = 2
error NTC- Air-Sensor
n = 3
error NTC- Evaporator-Sensor
n = 4
error NTC- Air- Evaporator Sensor
n = 5
With the help of a reset you can see the fault signal (n) again.
In case an error is recognised (n>2), the temperature adjustment will not be
started, and the heating element will not be switched on.
The inner lighting and the Red-Dot will flash with ca. 4 Hz.
