4.
Gently pull the cover straight off the base. (See figure 2.)
5.
Put the thermostat base against the wall where you plan to mount it. (Be sure the wires will
feed through the wire opening in the base of the thermostat.)
6.
Mark the placement of the mounting holes.
7.
Move the base out of the way. Drill mounting holes. Use a hammer to tap in the supplied
anchors into the mounting holes.
8.
Fasten the base loosely to the wall as shown in Figure 1, using two mounting screws. Place a
level against the bottom of the base and adjust until level, then tighten the screws. (Leveling is
for appearance only, and will not affect thermostat operation.)
9.
Insert stripped, labeled wires into matching wire terminals. See “Wiring Diagrams”, Section 3,
Figure 3.
CAUTION: Be sure exposed portions of wires do not touch other wires.
10.
Tighten screws on terminal block. Gently tug on each wire to be sure of proper connection.
Double check that each wire is connected to the proper terminal.
CAUTION: Installing batteries backwards can damage the thermostat.
11.
Install two fresh “AAA” alkaline batteries in the battery compartment. Be sure to match
positive (+) ends of batteries with positive (+) battery terminals in the battery compartment.
(The thermostat will operate from 2 size “AAA” alkaline batteries or 24VAC power. When
operated from 24VAC power, your thermostat will maintain time and continuously display the
temperature during a loss of AC power with the batteries installed).
12.
Replace the cover on the thermostat by snapping it in place.
13.
Turn on power to the system at the main service panel.
