Yes switch is on .... Digital thermo. I've used before for ac and controls both zones, and I thought when you cycle through the modes there was an option for heat, and also heat pump.
What's fantastic fan?
The fantastic fan is the roof exhaust fan that is in the kitchen area (at least it is in our HR). With the vent hatch opened the fantastic fan thermostat controls when the fan runs.
As far as the rest is concerned, it sounds like the thermostat control for the heat/heat pump is not working because the proper modes are not appearing when choosing on the thermostat. I replaced my thermostat a few years ago, not that expensive. Next step could be that the main control board is bad. This is located usually in the zone 1 unit. JMHO
