Carrier Infinity does not work with Control4 Thermostat
I have Carrier airconditioners in the house. A couple of them are the new Infinity systems with Infinity thermostats. They worked just fine. Then I installed a Control4 system in the house. They removed the thermostats for the non-Infinity Carrier systems and from the Infinity Carrier systems. They replaced all thermostats with Control4. Bottom line: the Control4 thermostats work with the NON-Infinity, but they do not work for the Infinity systems.
Carrier has said that only Infinity thermostats work with Infinity systems.
Should still have the standard terminals in the equipment. At least the furnaces did.
So someone will have to rewire the actual equipment.
And if its staged equipment, you may need to pull new thermostat wires.
