Climatemaster Geothermal: GSV/GSH Re: Flashing Code 3 / Loss of Charge Code 3 = Low Pressure Fault The low pressure switch must be open and remain open for 30 continuous seconds during an “on” cycle to be recognized as a low pressure fault. If the low pressure switch is open for 30 seconds...

ClimateMaster Heat Pump: Heating Re: Code 4 / LT1 Fault Code 4 = Low Water Coil Temperature (FP1) The FP1 thermistor temperature must be below the selected low temperature limit setting* for 30 continuous seconds during a compressor run cycle to be recognized as a FP1 fault. *JW3 Clipped...

ClimateMaster Heat Pump: GSV/GSH Re: Flashing Code 5 / LT2 Fault (Cooling) Code 5 = Low Air Coil Temperature (FP2) The FP2 thermistor temperature must be below the selected low temperature limit setting (30 deg. unclipped) for 30 continuous seconds during a compressor run cycle to be...

ClimateMaster Heat Pump: Heating / Cooling Re: Code 6 Code 6 = Condensate Overflow The condensate overflow sensor must sense overflow level for 30 continuous seconds to be recognized as a CO fault. Condensate overflow will be monitored at all times. Qty Possible Causes: 2...
