Frequently Asked Questions

The type of thermostat you need for your AC unit depends on the type of system you have installed.
Most thermostats require at least five wires for proper installation, although some systems may require more or fewer wires depending on the complexity of the system and the components included in it.
The correct wiring sequence depends on your specific model, but generally involves connecting each wire to its corresponding terminal on both the thermostat and the AC unit.
