Remark: (If the product has no heat exchanger sensor from -25
℃
to -50
℃
, failures E3 and E4 will not
happen to it.)
(If the product has an independent backup system, failures E0, E1, E3 and E4 will not happen to it.)
Alternative display time: the actual temperature is displayed for 6s and the failure code is displayed for
2s.
6.5 Probe resistance changes with the change of the temperature (probe type: NTC,
mainly for ambient temperature sensor, condenser temperature sensor and heat
exchanger sensor)
