Hi,

I have a Confort Zone II system (from Carrier) installed at home.
Sensors are always reading 28C.

In the same room I have the thermostat of the heating system and this is working, when I switch on the HVAC, this thermostat shows the temperature going down from 30 to 26, but machine never stops !!! because HVAC thermostat is always showing 28C.

What can be wrong here ??

Thank you!!

(sorry if my english is not perfect)
