Heat pump communication
If the Panasonic is not successfully communicating with Passiv Smart Thermostat then check the following:
- Check the RS485 cable connections on the Intesis module within the Panasonic outdoor unit, and confirm continuity back to the previous device
- Check the DIP switches are in the correct position
- Check that the RS485 termination resistor is not connected in BOTH the Passiv Programmer and the Intesis module
Configuring the panasonic heat pump
For the Passiv Smart Thermostat to operate correctly it is essential that the Panasonic heat pump settings have been changed correctly. In the event of retrofitting the Passiv Smart Thermostat to an existing installation, it may be optimal to return the heat pump to factory defaults first.
