If you have thermostat compatibility problems with a heat pump in your Greater Vancouver home, here is what usually causes it and how HeatLand fixes it.
Common causes
This is usually caused by the thermostat lacking O/B terminal support, missing auxiliary heat staging, or voltage incompatibility with the heat pump controls.
What you can check
Replace batteries, confirm the breaker has not tripped, and check the system mode and fan setting are correct. Make sure the filter is clean and vents are open. If those steps do not resolve it, call a licensed technician.
How HeatLand diagnoses and fixes it
We trace the wiring, test the thermostat signal to your HVAC system, identify the fault, and fix it – whether that means reconfiguring, adding a C-wire, or replacing the thermostat. See our thermostat services.
Repair or replace?
If your thermostat is causing repeated problems or is over 10 years old, replacing it with a modern model often makes more sense and may qualify for a rebate.
