Wiring terminals
This section describes the procedure for connecting the wiring to the back plate.
(Fig. 4) shows the Wiser Air backplate conguration.
When replacing an older thermostat, refer to the photograph of the original wiring
taken in Step 3 of the installation procedure to connect the wiring to the correct
terminals. See the caution below.
For a new installation, consult the documentation for your HVAC system to determine
the correct wiring terminal connections. Match the wiring labels to the terminal labels.
For more information or assistance in determining the correct wiring for your HVAC
system, see the HVAC wiring help sections on the Wiser Air website
(www.wiserair.com/support).

EQUIPMENT
OPERATION HAZARD
• You must remove the
backplate jumper if your old
system had separate wires
connected to RC and RH.
• Never use any tools on
screwless terminals of
Wiser Air.
Save the backplate jumper for
future use.
NOTICE
TIP: To ensure that Wiser Air is wired correctly. Place the thermostat in either heating or cooling
mode. Set the set point 2 degrees above or below the current temperature. Conrm that your
system engages in either heating or cooling. For heat pumps, an additional step is required
to check auxiliary heating. Set the set point 5 degrees below the current set point. The air
should feel noticeably warmer than the 2 degree check.
