Troubleshooting and error codes
| Problem | Possible Causes | Correctives |
|---|---|---|
| Zoneline does not start. | Direct connect harness is not attached securely. | Remove junction box cover and ensure the black connector on the power cord is inserted securely. |
| The air conditioner or heating of the Zoneline is insufficient. | Indoor airflow is restricted. | Ensure the front of the Zoneline is not blocked by curtains, blinds, or furniture. |
| A burning smell is perceived at the beginning of operation in heating mode. | Dust is present on the heating elements. | Dust can cause a burning smell at the beginning of heating mode. This should disappear rapidly. |
| The air is not always hot or cold during operation. | The temperature in the room was perhaps too low or too high. | Adjust the temperature to a lower or higher value. The temperature limiter may restrict the range of values. |
| The air seems not warm enough in heating mode. | The heat pump alone supplies air that is slightly less warm than desired. | Use the Boost Heat (Mode 9 AUX) or All Electric Heat (Mode 8 AUX) option. Note: Using these options will increase energy consumption. |
| The unit does not blow air. | The fan setting (ventilator) of the wall thermostat is perhaps set to "auto". | If you want air to circulate even when the Zoneline is not actively heating or cooling the room, set the wall thermostat to "on". |
| Electric heating and ventilation functions do not work. | The Personality jumper is not securely connected. | Remove the junction box cover and ensure the black connector on the power cord is inserted securely. |
| The unit does not operate after the remote wall thermostat installation. | Incorrect thermostat connections. | Verify that the wiring between the thermostat and the unit's thermostat connector is correct. |
| The heat pump operates with electric heat only during heating. | Auxiliary mode 8 is not set correctly. | Refer to the Auxiliary Control Settings section. Verify if auxiliary mode 8 is set to OFF for heat pump operation. |
