Check thermostat room probe
Due to environmental conditions
Due to unfavourable system conditions
Check the VMF-E2/E4 panel attached to the relevant thermostat for
proper connection or electrical integrity.
Check the inverter functioning or wiring reporting the inverter state to the
thermostat.
Check correct RS485 bus connection.
Check address (1) and the RS485 bus for proper connection.
Due to unfavourable system conditions (heat pump, exchanger or
