* 1: If the thermistor temperature data is normal (not open/ short), that data is loaded into the control as valid data.
When the unit enters emergency operation and TH values are mismatched, set the thermistors
to open/ short. And the unit runs emegency operation with the values listed above.
* 2: If one thermistor is set to open/ short, the values for each will be different from the list above.
[Ex ample] When liq uid pipe temperature thermistor (TH3) has an open or short circuit.
