Detach the connector (CN4) from the room
temperature thermistor and heat exchanger
thermistor and measure the thermistor resistances.
Did the resistances almost agree with those indicated
in the right-hand figure?
The product will begin detecting failures if it is
close to a wire break or short-circuit.

Are the room temperature thermistor, heat exchanger
thermistor connector (CN4)
[Situation] The timer lamp blinks 9 times and the product will not run.
[Estimated failure location]
䊶
Loose connector, wire break, or short-circuit in the room temperature
thermistor, heat exchanger thermistor.
[Cautions]
䊶
Starting the product by remote control will initiate failure detection.
(Merely turning on the power will not activate the failure detection function.)
