ZONING CONTROL PANEL CHECK

For zoned systems, install the C Wire Adapter

between the thermostat and the zoning panel, NOT

between the zoning panel and HVAC equipment.

3Take a picture of the wiring.

Ensure the terminal labels

and wires are in the image.

You may need to reference

the picture later.

Confirm that you do not have

a wire in the C terminal. If

you have a wire in the

C terminal, then you do not

need this product.

Look for an unused wire. If

you have an unused wire,

then you do not need this

product. Connect one end of

that wire to C terminal at the

HVAC and the other to C

terminal at new thermostat.

*The C wire (common) might be

labeled as B rather than C on certain

thermostats.

Go to your HVAC system. It may be located in your

attic, crawl space or basement.

*Not all systems will have a

W or W1-wire. On a heat pump

application, the wire coming from

O/B on the old thermostat would

match to either O or B at equipment

rather than W.

**If multiple wires are connected

to a terminal, only label the the wire

running to your thermostat.
