Why is my iO HVAC Controls Thermostat temperature display inaccurate?
If your iO HVAC Controls Thermostat's temperature display is inaccurate, it might be due to air leaking from the wall cavity into the thermostat's rear. To fix this, seal the hole where the wiring enters the subbase to prevent air infiltration. Also, external factors like lamps or drafts can affect the accuracy. Ensure to move any heat sources away from the thermostat.
What to do if the iO HVAC Controls Thermostat fan keeps running?
