5.4.3
Checking the heating pump’s NTC sensor electrically
1. Measure the resistance of the NTC sensor at contacts 2 - 1 and 2 - 3 (the
measurements should be equal).
2.
0
If the resistance
does not
agree with the value given in the circuit diagram
►
replace the defective heating pump. (Page 74)

Checking the heating pump’s BLDC motor electrically
1. Measure the resistance of the BLDC motor at contacts 2 - 1, 2 - 3 and 1 - 3 (the
measurements should be equal).
2.
0
If the resistance
does not
agree with the value given in the circuit diagram
