INSTALLATION

WARNING
!
Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.
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 adapter
plate. Before removing wires from old thermostat, label
each wire with the terminal designation from which it
was attached. Disconnect the wires from the old thermo-
stat 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 snug-
ly, use plastic screw anchors to secure the base.
4. Fasten base snugly to wall using mounting holes shown
in Figure 2 and two mounting screws. Leveling is for
appearance only and will not affect thermostat operation.
5. Connect wires to terminal block on base.
6. Push excess wire into wall and plug hole with a fi re re-
sistant material (such as fi berglass insulation) to prevent
drafts from affecting thermostat operation.
7. Carefully line the thermostat up with the base and snap
into place.
SS/HP Switch
(Conventional or Heat Pump Selection)
The SS/HP switch is factory set to the SS position. In this posi-
tion, thermostat is confi gured as conventional single stage. If
you have a single stage heat pump system, switch SS/HP to
HP position (see fi gure 2).
Gas/Elec Switch (Fan Option)
The GAS/ELEC switch is factory set to the GAS position. In
this position, the thermostat will not power the circulator fan on
a call for heat, but will power the circulator on a call for cool.
If your system requires that the thermostat power the circula-
tor fan on a call for heat, this switch should be set to the ELEC
position. Typically, gas and oil heating systems do not require
the thermostat to power the circulator fan during a call for heat.
If your heat is gas or oil, the switch should be set to the GAS
position.
When the thermostat is confi gured for Heat Pump, the thermo-
stat will always power the circulator fan on a call for heat in the
HEAT mode.

WIRING CONNECTIONS

Refer to equipment manufacturers' instructions for specifi c system wiring information. After wiring, see CONFIGURATION
section for proper thermostat confi guration. Refer to 37-6754 for 1F80-0471 wiring diagram specifi cations.

Batteries
2 "AA" alkaline batteries are included in the thermostat. To in-
stall the batteries, pull the battery door as shown by the arrow
and lift open. Using the polarity indicated inside the battery
door, insert the batteries. To close the battery door, swing the
door down while pulling in the direction of arrow. Once fully
down, snap the door back into position.
To replace the batteries, set system to OFF, following the
instructions above.
Thermostat can be powered by system AC power or Battery.

(over 3 months) and
be replaced before leaving. When less than two months of
battery life remain, the setpoint temperature will offset by
