Climatemaster Geothermal: TE Re: Diagnostic Tool / Communicating Thermostat The communicating Climatemaster thermostat can act as a diagnostic tool with the following features: Thermostat Configuration System Configuration Airflow Selection Option Selection Unit Configuration ...

Climatemaster Geothermal: TE Re: Code 2 / High Pressure Fault - Cooling Code 2 = High Pressure Fault When the high pressure switch opens due to high refrigerant pressures the compressor relay is de-energized immediately since the high pressure switch is in series with the compressor contactor...

Climatemaster Geothermal: Heating Re: Code 2 / High Pressure Fault Code 2 = High Pressure Fault When the high pressure switch opens due to high refrigerant pressures the compressor relay is de-energized immediately since the high pressure switch is in series with the compressor contactor...

Climatemaster Geothermal: Heating / Cooling Re: 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...

ClimateMaster Heat Pump: Heating Re: Code 4 / LT1 Fault Code 4 = Low Water Coil Temperature (FP1 or LT1) The LT1 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 LT1 fault. ...

ClimateMaster Heat Pump: Cooling Re: Code 4 / LT1 Fault Code 4 = Low Water Coil Temperature (FP1 or LT1) LT1 FAULT SHOULD ONLY OCCUR IN THE HEATING MODE. AN LT1 FAULT IN COOLING MODE TYPICALLY INDICATES A BAD SENSOR. The LT1 sensor is located on the Water Coil side of the expansion...

ClimateMaster Heat Pump: Cooling Re: Code 5 / LT2 Fault 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 recognized as a FP2...

ClimateMaster Heat Pump: Heating Re: Code 5 / FP2 Fault Code 5 = Low Air Coil Temperature (FP2) ► There should be no normal reason for an FP2 Fault in the Heating mode. LT2 should only get cold in the Cooling mode. The FP2 thermistor temperature must be below the selected low temperature...

CLIMATEMASTER GEOTHERMAL Re: Code 8 Code 8 = Unit Performance Sentinel (UPS) Warning The UPS warning is NOT a Lockout condition. The UPS feature is intended to indicate when the heat pump is operating inefficiently. A UPS condition exists when: In heating mode with compressor...

ClimateMaster Heat Pump: TEV Re: Code 10/ECM Blower Fault When operating an ECM blower, there are two types of ECM Blower fault conditions that may be detected: An ECM blower fault will be detected and the control will lockout after 15 seconds of blower operation with the blower feedback...
