Check Your HVAC Compatibility

Most central heating and cooling systems are compatible with our thermostats.

Answer a few quick questions to confirm your system type.

The process takes about 5 minutes.

Start Find a professional

Step 1: Turn Off Power

Switch off power to your HVAC system at the breaker panel or system switch.

This ensures your safety and protects your equipment.

Power is off

Step 2: Remove Your Thermostat

Gently pull the thermostat straight off the wall plate.

If needed, loosen the mounting screws first.

Avoid pulling on the wires.

Thermostat removed

Step 3: Check Your Wiring Type

Our thermostats work with low-voltage (24V) systems using thin solid wires.

Your system is NOT compatible if you see:

Thick wires
Stranded wires
Labels like 120V, 240V, L1 or L2

I see only thin solid wires (24V system) I see high-voltage markings or thick wires

High-Voltage System Detected

It looks like your system uses high voltage.

No problem — we likely have an option for you.

Go to High-Voltage Thermostat Selector

Step 4: Check Your Thermostat Base

In the next step, you’ll need to select the wires connected to your thermostat base.

Important:

Only select wires coming from the wall
Do NOT select any jumpers

A jumper is a small wire that connects two terminals (such as Rc and Rh).

It does not come from the wall.
Ignore jumper wires when selecting your wiring.

Make your selection

Select all the terminals on your thermostat base that have wires connected coming from the wall.

Watch for dual terminal labels

Some thermostats display two sets of labels for each terminal

One set for conventional systems (often marked “conventional” or without specific indication)
Another set for heat pump systems

Use the label set that matches your HVAC system type.
