4-4-40 Outdoor Temperature dislocation error
1. How to check
Is an outdoor temperature sensor
connector dislocated from the PCB?
Does the resistance value
greatly deviate from the
temperature table to the next?
After separating the outdoor temperature sensor
connector from the PCB, measure the resis
-
tance value between both terminals.
Restart after replacing the PCB
Restart after connecting
the connector to the PCB.
As it is due to a problem with
the outdoor temperature sensor,
replace it.
