HVAC System Connection

The thermostat connects to the HVAC system’s thermostat connections just like a traditional thermostat does.

HVAC System Compatibility

The thermostat is compatible with most heating and cooling systems. There are two types of HVAC systems: Standard (gas/electric) and Heat Pump systems. The system type is selectable from the Installer Screen – System Settings – Mechanical Settings submenu.

For Standard HVAC systems: Gas heating or Electric heating.

For Heat Pump HVAC systems: supports changeover valve operation for either changeover with cooling or changeover with heating.

Multi-Stage HVAC Compatibility

For Standard HVAC systems, the HVAC outputs support 2 stages of heating and 2 stages of cooling.

For Heat Pump HVAC systems, the HVAC outputs support 3 stages of heating (2 compressor/1 Aux Heat) and 2 stages of cooling.

Dual Fuel

NOTE: This thermostat is not compatible with dual fuel systems, without a dual fuel kit. (Heating system with both heat pump and gas furnace.) If you need a dual fuel kit, please contact a qualified heating and cooling contractor.

Remote Communications

The Z-WAVE thermostats have a Z-Wave communications module for communicating to control systems with Z-Wave capability.
