124 Er 20: TWR sensor faulty Replace sensor
120 Er 22: TPM or TWR shutdown sensor faulty Replace sensor
136 Er 23: TPV sensor faulty Replace sensor
118 Er 24: Buffer sensor faulty Replace sensor
114 Er 29: TWV sensor faulty Replace sensor
11 11 Er 30: Phase monitor Check power supply
134 Er 32: THG sensor faulty Replace sensor
138 Er 33: High pressure sensor faulty Check sensor
137 Er 34: Low pressure sensor faulty Check sensor
5 5 Er 36: High pressure Deficient heat distribution, faulty circulation pump, valve closed or air in the
system, check hydraulics
18 18 Er 37: Low pressure Lack of source energy, lack of refrigerant, expansion valve, check refrigerant
circuit (by OCHSNER Customer Service)
16 16 Er 38: Hot gas Expansion valve, lack of refrigerant, target temperature too high, check re-
frigerant circuit (by OCHSNER Customer Service)
10 10 Er 39: Compressor motor protection Motor overload relay, phase fault/overload, source temperature too high,
check compressor in refrigerant circuit (by OCHSNER Customer Service)
8 8 Er 42: Heat sink frost protection Deficient heat distribution, faulty circulation pump, valve closed or air in the
system, check buffer charging pump or hydraulics (brine antifreeze level)
Er 46: TSG sensor faulty Replace sensor
