Solenoid Valve
-3- Temperature sensor
Perform a check while comparing sensor detection temperature and measured value.
See the diagram below for comparison with sensor resistance value.
1. High temperature thermistor (TH1, TH2, TH101, TH102)
2. Low temperature thermistor (TH3, TH4, TH5, TH6, TH7, TH8, TH9, TH10, TH11, TH12, TH103, TH104, TH105, TH106,
TH107, TH108, when there is a representative water temperature sensor (TH116, TH117))
3. Thermistor (THHS)
