OPERATION
4
，
Your Thermostat is designed to operate with most gas, oil, electric or 2-wire hot water
heating and air conditioning systems. It will also operate single-stage heat pumps that do
not have auxiliary or emergency heat.
These have 24-volt or millivolt control systems and represent most central heating, air
conditioning, or space heating units in use in the United States.
This Thermostat will NOT control multi-stage heat pumps or 110/220Volt systems.
COMPRESSOR PROTECTION
5, The thermostat provides a 4 minutes delay after shutting of the heating or cooling
system before it can be restarted. This feature will prevent damage to your compressor
caused by rapid cycling. Note that this delay also applies to the heating system control. It
does not provide a delay when there are power outages.
Temperature Range
This thermostat can be programmed between 45
˚
F and 95
˚
F (7
˚
C and 35
˚
C). However, it
will display room temperatures from 30
˚
F to 99
˚
F (0
˚
C and 37
˚
C). “HI” will be displayed if
the temperature is higher than 99
˚
F (37
˚
C), and “LO” will be displayed if the temperature
is lower than 30
˚
F (0
˚
C).
This thermostat will automatically cutoff in Heat mode if the temperature rises above
95
˚
F (35
˚
C), and automatically cutoff in Cool mode if the temperature drops below 45
˚
F
(7
˚
C).
NOTE: The thermostat will automatically change to the Cool mode if the thermostat
measure a temperature over 99
˚
F(37
℃
), ”HI” will be displayed on the LCD, and the
Cooling system will turn On. Similarly, the thermostat will automatically change to the
Heat mode if the temperature is below 32
˚
F(0
℃
). and ”LO” will be displayed on the LCD,
and the Heating system will turn On.
POWER FAILURE
7, Whenever the main power is interrupted or fails, the battery power retains and current
time.
AUTO RECOVERY
8, Your thermostat is set from the factory to gradually recover the room temperature from
an energy saving program to your comfort program. Therefore, the thermostat may turn
your system on several minutes prior to your programmed the Selector Switches
information on Selector switches
BATTERY WARNING
9,Fresh alkaline batteries should provide over one year of service. However, when the
batteries become drained, “BATT” will alternate on the display with the current time.
When this message occurs, install 2 new AA batteries, You have approximately 1 minute
to change the batteries and keep thermostat’s clock and program settings. Once the
batteries have become too low to ensure proper operation, your system will be turned
Off, and the display will be cleared except for “BATT” flashing on the LCD display.
CAUTION:
Once only the “BATT” only display occurs, the thermostat is shut down, and
your system will no longer operate. In this condition, there is no temperature
control of your dwelling.
NOTE: The backlight will not function when the
thermostat is in low battery condition.
NOTE: If you plan to be away from the premises over 30 days, we recommend that
you replace the old batteries with new alkaline batteries prior to leaving.
INSTALLATION
What You Need
This thermostat includes two #8 slotted screws and two wall anchors for mounting. To
install your thermostat, you should have the following tools and materials.
y
Slotted Screwdriver(s)
y
Small Philips screwdriver
y
Hammer
y
Electric drill and 3/16” bit
y
Two1.5V (AA) size alkaline batteries (included)
Remove Old Thermostat
CAUTION: Do not remove any wiring from existing thermostat before reading the
instructions carefully. Wires must be labeled prior to removal.
INPORTANT! Turn off the power to the furnace at the main power panel or at the
furnace.
Remove existing thermostat cover and thermostat. See Figure 1. Some thermostats will
have screws or other locking devices that must first be removed. Once the wall mounting
plate is exposed, look for wires. If wires are not visible, they may be connected to the
back of the wallplate. Again, look for screws, tabs, etc. Some models have doors that
open to expose wires and mounting screws. See Figure 1.
Typical Home Thermostats
Wall mounting Plate Thermostat Cover
Wiring Labeling
y
Each wire coming from the wall to the existing thermostat is connected to a terminal
point on that thermostat. Each of these terminal points is usually marked with a code
latter as shown in Table A below.
y
Note that this thermostat has multiple function terminals that allow Single-Stage Heat
Pump capability. Standard systems use: Rh, Rc, G, Y, W. [Single-Stage Heat Pumps use:
R, Y, G, and O or B.] Table A below shows the multiple functions of the terminals. Use the
terminals that match your system.
y
The number of wires in your system can be as few as two (for heat only systems), as
many as eight, or any number in between. If you follow the labeling procedures correctly,
you do not have to be concerned about how many wires there are.
y
There is often no terminal marking on the existing thermostat of two wire, heat only
systems. Just connect either of the wires to the RH terminal, then connect the other wire
to the W terminal to complete the circuit.
y
IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY THE
SELFADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLE A
BELOW.
(For example, attach the label marked W to the wire that toes to the W or H
terminal on your existing thermostat.) IGNORE THE COLOR OF THE WIRES since
these do not always comply with the standard.
y
After labeling wires, disconnect them from the existing
thermostat.
y
Remove existing wallplate. To make sure wires do not fall
back into wall opening, you may want to tape them to the wall.
y
If hole in wall is larger than necessary for wires, seal this hole
with insulating material so that no hot or cold air can enter the
back of the thermostat from the wall. This air could cause a false thermostat reading.
If the code letter on
your existing
Thermostat is
then mark the wire with
label shown
and connect to
thermostat terminal
shown
Table A
NOTE: Do not connect a “Common” wire (sometimes labeled “C”) to any terminal on this
thermostat. Tape up the wire and do not use. This wire provides electricity to non-battery
powered thermostats.
Mount Wallplate and Thermostat Figure 2
y
Remove the wallplate from your
thermostat by pressing the release
tab on the bottom of the thermostat.
See Figure 2.
y
Position wallplate on wall and pull
existing wires through large opening.
Then level for appearance. Mark
holes for plastic anchors provided,
if your existing holes do not line up
with those on the wallplate.
y
Drill holes with 3/16” bit and gently
tap anchors into the boles until flush
with wall.
y
Reposition wallplate to wall, pulling
wires through large opening. Insert
mounting.
Figure3
screws provided into wall anchor and tighten. See Figure 3.
NOTE: 5- Wire Systems
If your thermostat has one wire marked R or Rh (2, 3, or 4-wire system), then leave the
jumper wire between the Rh and Rc terminals on the wallplate. Otherwise, if you have
separate Rh and Rc wires (5-wire system), then remove the jumper wire between the Rh
and Rc terminals.
Connect Wires and Mount Thermostat to Wallplate Figure 5
y
Match and connect the labeled wires to
the appropriate coded terminal screws
on the wallplate. (See Figure 4, 5)
Ignore any wires which may be present,
but which were note connected to the
old thermostat.
y
Refer to the Wiring Diagrams
below to be sure your system is wired
correctly.
y
Be sure to tighten the terminal screws securely, otherwise a loose wire could cause
operational problems with your system or thermostat.
y
Push excess wire back into the hole to prevent interference when installing the
thermostat to the wallplate.
y
Make sure the System Switch is set to OFF, and the Fan Switch is set to AUTO.
y
If your system is a single stage heat pump and uses an O or B wire, you must move the
System Selector switch inside the thermostat to the Heat Pump position. If you have a
normal furnace or electric system, leave the switch in the Standard position. Refer to the
System Selector section on the back for more information on this switch.
y
Insert the tabs on top of the thermostat body into the slots at the top of the wallplate.
Press the bottom of the thermostat body into the snap on the bottom of the wallplate, as
the terminal pins may be damaged. If it does not snap properly, the thermostat may not
work.)
y
Insert the two AA size alkaline batteries, observing the polarity marked inside the
battery compartment.
y
Switch on the main power at the panel or furnace.
Selector Switches
In order for this thermostat to control your system, the system type must be specified by
the selector switches on the printed circuit board inside the thermostat. There is also a
selector switch for your choice of Fahrenheit or Celsius temperature display.
y
Heating System Selector (HG – HE switch)
The factory position for this switch is in the “HG” position. Leave in this position if you
have a gas furnace or an oil burner. If you have an electric furnace, test to see whether
the Heat and Fan come on as expected after installation. If the Fan operation is normal,
leave it in the “HG” position. If the Fan does not come on within minute of the thermostat
calling for heating, change the switch position to “HE”. The system selector has no effect
in the cooling mode.
NOTE: “HG” position is for gas and most other systems. “HE” position is for certain
electric systems having a fan relay.
y
Furnace or Heat Pump selector (NORMAL-O-B switch)
T
he factory position for this switch is in the
NORMAL position. Leave it in this position
if you have ANY system that uses gas, oil,
electric, or hot water heating.
If you have a single-stage Heat Pump (no
auxiliary or emergency heat source), then
slide the switch to the position that
matches your Reversing Valve type. If your
heat pump system has a “B” wire, slide the
switch to ”B” for your reversing valve that
activates in HEAT mode. If your heat pump system has an “O” wire, slide the switch to
“O” for your reversing valve that activates in COOL mode.

as much as 33%. By setting your thermostat up 5
˚
F (3
℃
) for tow 8 hour perids during
summer you can reduce your fuel bill up to 25%.
Your thermostat is capable of holding up to 4 separate programs for each day of the
week. You can program all weekdays, Monday to Friday, to the same 4 programs as
show in the table, or each weekday can have a different set of 4 programs. Simillarly
weekend programs, Saturday and Sunday, can be the same 4 programs or each
weekend day can have a different set of 4 programs.
Your thermostat is pre-programmed to meet the ENERGY STAR guidelines for energy
efficiency. Note that it is easier to modify these programs than to programs than to
program the thermostat manually.
