Save the Mente PC data of
30 minutes before stopping
NO
Is the
connector of the
anomalous sensor
connected
properly?
YES
NO
Are
the characteristics
of sensor OK?
*3
YES
・
Check the operation
status and record it.
・
Check it occurs soon
after power ON or during
operation or during
stopping.
・
Check sensing value
・
Compare the temperature
shown in menteP C data
to the acutal temperature
measured with
thermometer.
Insert the connector securely
Replace temperature sensor
(Tho-S, Tho-IN J)
Replace the control P CB of
heat pump water heater
. E rror detection method
Detection of anomalously low
temperature (resistance) of
temperature sensor. (Tho-S,
Tho-IN J)
. Condition of error displayed
If the sensor detects -0° C or
lower temperature for seconds
continuously
. P resumable cause
・
Broken sensor harness or
the internal wire of sensing
section (Check the molded
section as well)
・
Disconnection of sensor
