Knowing your correct Equipment Type

This article will help you learn your HVAC system and configure the correct Equipment Type for your ENASTAT Full Circle

Your ENASTAT Full Circle is compatible with many different types of HVAC (Heating, Ventilation, and Air Conditioning) systems and it is important to configure your device correctly according to your HVAC system type.

Single stage and multistage HVAC systems are two common types of systems used in residential and commercial buildings, but there are many other types of systems.

Please confirm with your HVAC technician the type of system you have, additionally  the wire labels and colors can be used as indicators to determine the type of system you have based on your previous thermostat or if you already have an ENASTAT installed.
