Owners Manual
Model : CP1919
We are pleased you have selected one of our broad line of wall thermostat. Our products
are manufactured to high quality standards and are design for years of service.
Read This Before Installing Thermostat
IMPORTANT
1 Read the entire installation of this Owner’s Manual thorough before your Thermostat.
Remove the mylar label from the display window.
INSTALLATION
2 All installation is normally performed at your thermostat.
PROGRAMMING
3 You can practice programming before installing your thermostat by inserting and
connecting the batteries. This can be done while you relax in your favorite chair and is a
very good way to familiarize yourself with all the functions of your Thermostat.
OPERATION
4 Your Thermostat is designed to operate with most gas , oil, electric or 2-wire hot water
heating, and air conditioning systems that have 24-volt or millivolt control.
This Thermostat will not control multistage heating or cooling systems, 110 / 220V
systems, or 3 wire zone systems.
COMPRESSOR PROTECTION
5 The thermostat provides a 4-minute delay after shutting off the compressor before it
can be restarted. This feature will prevent damage from your air conditioner compressor
caused by rapid cycling. It does not provide a delay when there are power outages.
Temperature Range
6 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).
POWER FAILURE
7 Whenever the main power is interrupted or fails, the battery power retains the
programs and current time.
Battery Warning
8 Two fresh AA alkaline batteries should provide well over one year of service. However,
when the batteries become drained, the Low Battery Indicator will flash on the display.
When this message occurs, install new alkaline batteries. You have approximately 1
minute to change the batteries and keep the 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 flashing Low Battery Indicator on the
LCD display.
CAUTION: When only the Low Battery icon flashes on the display, 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.
How This Thermostat Works …And Saves Your Money
This thermostat is designed to optimize the use of your heating and cooling equipment. It
does this by matching your comfort (the temperatures in your home) to your schedule.
An example:
6am – You wake up. Program 1 has the heat set to 70°(21
℃).
7:30am – You leave for work. The second program turns the heat back to
62 ℃(17℃) while you are away.
5:00pm – You come home. The third program has already warmed your house
back to 70°(21 ℃) .
10:00pm – You go to bed. A half hour later, program 4 turns the heat back to
64°(18 ℃) to save energy while you are under the blankets.
FEATURES
Installation
What You Need
This thermostat comes with two #8 slotted screws and two wall anchors for mounting. To
install your unit, you should have the following tools and materials.
■ Slotted screwdriver ■ Electric drill and 3/16” bit
■ Hammer ■ Two 1.5V(AA) Size Alkaline batteries are include.
Remove Old Thermostat
CAUTION: Do not remove any wiring from existing thermostat before reading the
instructions carefully. Wires must be labeled prior to removal.
■ IMPORTANT! 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 thermostat
will have screw or other locking devices that must first be removed. Once 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).

Label Wires
■ Each wire coming from the wall to the existing thermostat is connected to a
terminal point on the thermostat. Each of these terminal points is usually marked
with a code letter as shown in Table A.
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 concerned about how many wires there are.
There is often no terminal marking on the existing thermostat of two wire, heat
only systems. Don not worry, just connect either of the wires to the RH terminal,
then connect the other wire to the W terminal to complete the circuit.
■ IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY THE
SELF-ADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLE A.
(For example, attach the label marked W to the wire which goes 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.
■ After labeling wires, disconnect them from the existing thermostat terminals.
■ Remove existing wallplate. To make sure wires do not fall back
into wall opening, you may want to tape them to the wall.
■ If hole in wall is larger than necessary for wires, seal this hole
so that no hot or cold air can enter the back of the thermostat
form the wall. This air could cause a false thermostat reading.
Wire Labeling
This table will help
you match the labels
to the wires so you
can attach them to
your thermostat.
NOTE: Follow the
labels when
connecting wires
since many
installations do not
follow color
coding of wires.
Wire Labeling
NOTE: If your thermostat has one wire marked R or RH (4-wire system), then
leave the jumper wire between the RH and RC terminals. Otherwise, if you
have separate RH and RC wires (5-wire system), then remove the jumper
wire between the RH and RC terminals.
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
Snap open the wallplate your thermostat by pressing the release tab on the bottom of the
thermostat.
Position wallplate on wall and pull existing wires through large opening. Then
level for appearance. Mark holes for plastic anchors provided if existing holes do
not line up with Hunter Thermostat holes.
Drill holes with 3/16” bit and gently tap anchors into the holes until flush with wall.
Reposition wallplate to wall, pulling wires through large opening. Insert mounting
s crews provided into wall anchor and tighten. (See Figure 2.)
Figure 2
Selector witches
The heating system selector and the ℉/℃ selector switches are located on the
Printed Circuit Board.
■ Heating system selector
The heating system selector is a switch on the Printed Circuit Board on the inside
of the thermostat. The switch is at “HG” position. Leave it 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. Leave the switch in the “HG” position. If the fan does not come on when
the thermostat calls for heat, 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.
■ ℉/℃ selector (Fahrenheit/Centigrade)
Your thermostat is set for ℉ mode from the factory. In order to
change to ℃ mode, slide the switch to ℃ and move the battery out hold any key
then place the battery again.
NOTE: Unless Move the battery out hold any key then place the battery again.,
the thermostat will not change the mode.
Auto Recovery select
Your thermostat is set from the factory
with the Auto Recovery Feature
enabled , which complies with the EPA
ENERGY STAR Program. If you prefer
to use normal recovery, slide the switch
to the ALT position.
Connect Wires and Mount Thermostat Cover to Wall Plate
■ Match and connect the labeled wires to the appropriate coded terminal screws on
the mounting plate.(See Figure 3, 4.) Ignore any wires which may be present, but
which were not connected to the old thermostat.
■ Be sure to tighten the terminal screws securely, otherwise a loose wire could
cause operational problems with your system or thermostat.
■ Push excess wire back into hole to prevent interference with mounting of the thermostat cover.
■ Make sure the Function Switch is set at OFF, and the FAN-AUTO Switch is in AUTO.
■ Insert the bottom tab on the thermostat body into the slot at the bottom of the
wallplate. Press top of the thermostat body to snap it into the wallplate. (NOTE:
Do not force the thermostat onto the wallplate, as the terminal pins may be
damaged. If it does not snap properly, the thermostat may not work.)
■ Insert the two AA size batteries, observing the
polarity marked on the unit.
■ The installation is now complete. Continue reading

Typical Suggested Summer
and Winter Programs for Maximum Savings
Studies conducted by the Department of Energy estimate that setting your thermostat back 10 ℉
for two 8-hour periods during winter can reduce your fuel bill by as much as 33%. By setting your
thermostat up 5
°for two 8-hour periods 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 shown in the table, or
each weekday can have a different set of 4 programs. Similarly weekend programs, Saturday and
Sunday, can be the same 4 programs or each weekend day can have a different set of 4
programs.
A typical set of programs is shown in Table 3.
