Testing the heating pump

5.7.1 Measuring the heater resistance
The heater resistance is measured on the heating contacts of the
heating pump.
Measured values when heater intact EU:
Contact 2 – 3:
Measured values when heater intact TC / USA:
Contact 2 – 3:
approx. 19 Ω ± 2 Ω
ca. 8,9 Ω ± 2 Ω
5.7.2 Measuring NTC resistance
The NTC resistance value is measured on the heating contacts of the
heating pump.
Measured values when NTCs intact and at 25 °C:
Contact 4 – 5:
Contact 5 – 6:
Contact 4 – 6:
Measured at 25 °C
Resistance measurement of the NTCs
►
The measurement of the NTC must result in
a symmetrical value.
approx. 10 KΩ ± 1 KΩ
approx. 10 KΩ ± 1 KΩ
approx. 20 KΩ
