Applying Power
Before applying power, fill in the chart in the Pop-Up Wizard section of
this manual.
When 24V AC power or battery power is first applied to the thermostat,
the display will show the model number followed by the Pop-Up Wizard.
The thermostat will start normal operation following the Pop-Up Wizard.
Power is applied to the thermostat two ways:
1. Installing the batteries.
2. Not installing the batteries and connecting the thermostat body to a
backplate that has the C terminal connected and 24V AC present.
NOTE: A thermostat powered by 24V AC will use the batteries as backup
power if the 24V AC fails.
Installing Batteries
To remove the battery compartment
gently squeeze the ribbed edges on
both sides.
The battery compartment will pull
down from the thermostat body and
will detach. Install two AA batteries
following the polarity as shown
inside the compartment. Place
compartment back into the
thermostat.
Connecting The Body
Attach the thermostat body to the backplate by holding it directly in front
of the backplate. The edges will match and the wiring connections will
make contact. Push the body in until it snaps in place.
