Carrier Debonair-33CS Thermostat Troubleshooting

PROBLEM	SOLUTION
Display on thermostat not illuminated.	Check for 24 vac at the R terminal connection. Terminal R must be connected for proper thermostat operation.
Cooling will not energize.	Select COOL mode. Decrease cooling set point to 10 degrees below room temperature. Check for 24 vac at Y1 terminal. If present, thermostat is operating correctly and problem is with wiring or equipment. If 24 vac is not present, replace the thermostat. Check for Compressor Cycle per Hour Limit. Cooling may be locked out.
Heating will not energize.	Select HEAT mode. Increase heating set point to 10 degrees above room temperature. Check for 24 vac at W1/ O/B terminal. If present, thermostat is operating correctly and problem is with wiring or equipment. If 24 vac is not present, replace the thermostat.
When using 4 wires (R,G,W,Y), the cooling equipment tries repeatedly to turn on, but can- not. At times the display dims or disappears.	There is not enough power available. Connect a 270 ohm, 10 watt power resistor at the air conditioning equipment between terminals W and C (non-heat pump applications only).

When controlling a heat pump, heat comes on during cooling cycle.	Configure thermostat for heat pump operation
When calling for cooling, both heating and cooling are energized.	The thermostat is configured for a heat pump. Configure the thermostat for non-heat pump operation
When controlling a commercial heat pump unit, unit runs in reverse or heating is always on.	Some commercial heat pumps require that Heat Pump Option on thermostat is turned OFF.

Carrier AC Thermostat Troubleshooting

SYMPTOM	WHAT TO CHECK
No LCD on temperature display	Check for 24vac between R and C at terminal connections. Both R and C must be connected for proper operation.
'E2' on temperature display	Brownout condition or too low of voltage to thermostat. Double check wiring and check for 24vac between R and C. E2 will clear 15 sec after proper voltage is restored.
'E1' on temperature display	Temperature sensor reading out of range. Check sensor for damage. If recycling power does not clear display, thermostat should be replaced.
'Clean Filter' on temperature display	After the selected number of hr of blower operation 'clean filter' will display on LCD.
This is to remind the homeowner to 'check' filter.
Press 'reset filter' button to clear display and reset timer to 0.
“—“ on temperature display	If the outdoor sensor is open, not connected, or shorted will be displayed in place of outdoor temperature.
Cooling will not come on	Select COOL mode. Set desired temperature to 10'F below room temperature. Simultaneously press FAN and INCREASE TEMPERATURE buttons to defeat timers. Check for 24vac at Y (first-stage) terminal.
If present, thermostat is OK and problem is with equipment or wiring. If not present, replace thermostat.
Heating will not come on	Select HEAT mode. Set desired temperature to 10‘F above room temperature. Simultaneously press FAN and INCREASE TEMPERATURE buttons to defeat timers. Check for 24vac at Y (first-stage) terminal (with heat pump) or W/W1 (with air conditioner) terminal.
If present, thermostat is OK and problem is with equipment or wiring. If not present, replace thermostat.

Carrier 33AWCS1 Thermostat Troubleshooting

Problem	Solution
Room Air Temperature Sensor Failure	If the sensor used to sense room air temperature, reads less than -45°C or greater than 65°C, it will be considered as failed and will display '-'.
Communication Failure	If the NUI does not receive CCN communication data from the CDU for 60 seconds, the display will show'E3' error code in the Temperature display zone and '-'in the Time Display zone. Under this condition the outside temperature will be blanked. 'E3' error code will be displayed and the other functionality will remain same. If this happens then check the communication cable between NUI and outdoor unit
Humidity Sensor Failure	If the sensor used to sense room Humidity reads less than 0 HR% or greater than 99 HR%, it will be considered as failed and will display '-'
EEPROM Failure	If the thermostat non-volatile memory (EEPROM) has failed, an 'E4' error will be shown in the room air temperature display. When this error is present and power is cycled to the thermostat all of the installer configurations, program schedule settings and user settings will be factory default values
