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.
Batteries
2 "AA" alkaline batteries are included in the thermostat. To install 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.

If
is displayed, the thermostat is battery powered. If
is not displayed, thermostat is system powered with
optional battery back-up. When battery power remaining is approximately half, the
"Change

ies immediately. For best results, replace all batteries with a
premium brand alkaline battery such as Duracell

gizer
. We recommend replacing batteries every 2 years. If
the home is going to be unoccupied for an extended period
(over 3 months) and
is displayed, the batteries should
be replaced before leaving. When less than two months of
battery life remain, the setpoint temperature will offset by
10 degrees (10 degrees cooler in Heat mode / 10 degrees
warmer in Cool mode). If offset occurs, the normal setpoint

SS/HP Switch
(Conventional or Heat Pump Selection)
The SS/HP switch is factory set to the SS position. In this position, 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 circulator 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.

1) Select Reversing Valve Output (SS/HP switch must be set
at HP, omitted if SS/HP switch is SS Position) – The O/B
option is factory set at "O" position. This will accommodate
the majority of heat pump applications, which require the
changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed
with this thermostat requires a "B" terminal, to energize the
changeover relay in HEAT, the O/B option should be set at
"B" position.
2) Program Options 1F80 only – This control can be confi gured
for 5/2 day or 5/1/1 day programming or non-programming
mode. The default setting is P2, indicating 5/2 day programming. The programs per week can be toggled to P3 or P0
by pressing the
or keys. A selection of 0 Days for
non-programmable will eliminate the need for EMR, and
that step in the menu will be skipped.
3) Select Cool Savings™ and value – Selects the Cool
Savings feature On or OFF. If selected On, press MENU
to select the amount of adjustment for the feature in Cool
mode with 1 (1°) being the least amount of adjustment and
6 (6°) being the most amount of adjustment. Default value
is 3 (3°). In normal operation "Saving" will appear under
"Fan".

Cool Savings is an optional energy saving feature that can
reduce your cooling costs. It is based on the principal that
lower indoor humidity makes a slightly higher temperature
feel more comfortable. Cool Savings operates during periods
of high demand which normally occur on the hottest summer
days when the cooling system may run for hours to reach
the thermostat setting. Long cooling run times also lower the
indoor humidity. Cool Savings very slowly adjusts the setpoint
temperature to make the setpoint closer to the displayed
temperature, to a maximum number of degrees selected.
Adjusting the setpoint temperature over a long cooling run
time allows the system to reach your set temperature and
turn off. The room temperature will actually be higher than
the thermostat displays, but the reduction in humidity will
allow comfort at the slightly higher temperature. When Cool
Savings is making adjustments, "Save" will show next to the
setpoint temperature and the room temperature may vary
within the adjustment range selected.
If this feature is selected OFF, no change will occur when
the cooling system is continually running during periods of
high demand.
INSTALLER/CONFIGURATION MENU
4) Energy Management Recovery: (this step is skipped if
confi gured to be non-programmable).
Energy Management Recovery (E) On enables the ther-
mostat to start heating or cooling early to make the building
temperature reach the program setpoint at the time you
specify. Heating will start 5 minutes early for every 1° of
temperature required to reach setpoint.
Example: If E On is selected and have your heating pro-
grammed to 65° at night and 70° at 7 AM. If the building
temperature is 65°, the difference between 65° and 70° is
5°. Allowing 5 minutes per degree, the thermostat setpoint
will change to 70° at 6:35 AM. Cooling allows more time per
degree, because it takes longer to reach set temperature.
5, 6 & 7) Cycle Rate Selection – The factory default settings
with SS/HP switch in SS position for Heat is medium
cycle (ME) and Cool is fast cycle (FA). For Heat Pump
(HP), the default setting is fast cycle (FA).
To change cycle rate, press the
Cycle rate differentials for different settings are:
Fast Medium Slow
MODE
FA ME SL
Heat (SS) 0.4°F 0.6°F 1.8°F
Cool (SS) 1.2°F – 1.7°F
Heat Pump (HP) 1.2°F – 1.7°F
8) Select Compressor Lockout CL OFF or ON – Selecting
CL ON will cause the thermostat to wait 5 minutes between
cooling cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already
have a time delay built in and do not require this feature. Y our
compressor manufacturer can tell you if the lockout feature
is already present in their system. When the thermostat
compressor time delay occurs, it will fl ash the setpoint for
up to fi ve minutes.
or key.
9) System Mode Confi guration – This thermostat is confi gured
for Heat and Cool with Auto changeover (SYSTEM switch with
Cool Off Heat Auto) default. It can also be confi gured for Heat
and Cool (Cool Off Heat), Heat only with fan (Off Heat), Heat
only without fan, Auto only (Auto Off), and Cool only (Cool
Off).
10) Select Backlight Display – The display backlight improves
display contrast in low lighting conditions. When the "C" terminal is powered, selecting backlight CdL ON will keep the light
on continuously. Select backlight OFF will keep the light on
momentarily after any key is pressed. When the "C" terminal
is not powered, the light will be on momentarily after any key
is pressed no matter whether the backlight is selected ON or
OFF.
11) Select Temperature Display Adjustment 4 LO to 4 HI.
Allows you to adjust the room temperature display up to 4°
higher or lower. Your thermostat was accurately calibrated
at the factory, but you have the option to change the display
temperature to match your previous thermostat. The current
or adjusted room temperature will be displayed on the left
side of the display.
12) Select F° or C° Readout – Changes the display readout to
Centigrade or Fahrenheit as required.
13)Select Filter Replacement Reminder and Set Run Time.
Select the "Change Filter" reminder On or OFF. If selected
On, press MENU to select the time period from 25 to 1975
hours in 25 hours increments. In a typical system, 200 hours
(default) of run time is approximately 30 days. After the selected time of blower operation, the thermostat will display
"Change Filter" as a reminder to change or clean your air
fi lter. When "Change Filter" is displayed, press MENU but-
ton to clear the display and restart the time to the next fi lter
change.
