| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | Heat Pump ignores Thermostat | Wiring mismatch or loose connection. | Check continuity of wires between the adapter and the thermostat. | | No Display/Error on Thermostat | No power to the adapter. | Verify the connection to the heat pump mainboard (fuse check). | | Short Cycling | Incorrect DIP switch settings. | Ensure the adapter is set to the correct mode (OpenTherm vs. On/Off) for your specific thermostat. | | Temperature Inaccurate | Faulty room sensor connection. | If a separate room sensor is wired into the QV60, ensure it is not located near a heat source or in direct sunlight. |
