Smart thermostat not connecting to HVAC — Valencia, Valencian Community
When a smart thermostat loses communication with your HVAC system, it may fail to trigger heating or cooling even though the display appears normal. Common causes include incorrect wiring during installation, a missing or underpowered C-wire, or an incompatibility between the thermostat model and the HVAC control board. A smart-home installer can verify wiring, add a C-wire adapter if needed, and ensure the thermostat communicates reliably with the furnace and air conditioner.
