WARNING
!
Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.
INSTALLATION
Battery Location
2 "AA" alkaline batteries are included in the thermostat at
the factory with a battery tag to prevent power drainage .
Remove the battery tag to engage the batteries .
To replace batteries, set system to OFF, remove thermostat
from wall and install the batteries in the rear along the top
of the thermostat (see Figure 1) . For best results, use a
premium brand "AA" alkaline battery such as Duracell
®
or
Energizer
®
.
Remove Old Thermostat
A standard heat/cool thermostat consists of three basic parts:
1 . The cover, which may be either a snap-on or hinge type .
2 . The base, which is removed by loosening all captive
screws .
3 . The switching subbase, which is removed by unscrewing
the mounting screws that hold it on the wall or adapt-
erplate .
Before removing wires from old thermostat,
label each wire with the terminal designation from
which it was attached . Disconnect the wires from the old
thermostat one at a time .
Do not let wires fall back into
the wall .
Installing New Thermostat
1 . Pull the thermostat body off the thermostat base . Forcing
or prying on the thermostat will cause damage to the unit .
2 . Place base over hole in wall and mark mounting hole
locations on wall using base as a template .
3 . Move base out of the way . Drill mounting holes . If you are
using existing mounting holes and the holes drilled are
too large and do not allow you to tighten base snugly, use
plastic screw anchors to secure the base .
4 . Fasten base snugly to wall using the mounting holes
shown in Figure 1 and two mounting screws . Leveling
is for appearance only and will not affect the thermostat
operation .
5 . Connect wires to terminal block on base using wiring
schematic on page 3 .
6 . Push excess wire into wall and plug hole with a fire
resistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation .
7 . Carefully line the thermostat up with the base and snap
into place .
