4.4.7 P06 diagnosis and analysis
4.4.7.1 Diagnosis
Code P06 is only possible in cooling mode. CodeP06 means heat pump tripped with too low
outlet water temperature detected by the temperature sensor TB installed on the outlet pipe of
water side heat exchanger. If TB has been lower than 4°C for 120 seconds, Heat pump will shut
down and the interface will display the faulty code P06. When TB is above 8°C for one minute,
Heat pump will be ready for next startup.
4.4.7.2 Possible causes
!
Temperature sensor TB isn’t connected properly or has malfunctioned.
!
Hydraulic module PCB damaged.
4.4.7.3 Analysis and action
Note:
1. Measure sensor resistance. If the resistance is too low, the sensor has short-circuited. If
the resistance is not consistent with the sensor’s resistance characteristic table, the sensor has
failed. Refer to Part 4, 4-5.1 “Temperature Sensor Resistance Characteristics”.
