2. Production Functions Overview
2.1 Applications
2.2 Features
1. When the temperature is outside the display range the words HI or LO will be shown on the display
instead of a number. If the temperature higher than the display range, it will read HI. If the temperature
lower than the display range, it will read LO.
2. Two AA batteries thermostat operates on last up to 1 year. The battery voltage symbol will flash to
indicate when batteries need replacement. When the battery voltage symbol flashes change batteries
as soon as possible.
3. When changing batteries replace batteries within 20 minutes of removing the old ones to maintain
programmed settings such as time and date.
4. The thermostat is shipped with a protective film on the LCD screen. To remove the film, pull away from
the corner.
5. Do Not use excessive force when attaching the thermostat to the wall bracket. Ensure all pins are
aligned correctly and firmly push the thermostat into position.
6. The thermostat contains precision electronics. Handle with care. Do not expose to dirt or moisture.

Run button: Once programming parameters have been set for time and function,
use the Run button to save and exit the programming interface. Press the Run
button once to run the time program that has been set.
Hold/Set button: Press the Hold/Set button once and the thermostat will stay in the
current mode and temperature setting. In heating/cooling mode, pressing the Hold/Set
button will hold the temperature that it is currently set at and will not change during
the setting process. In the heating/cooling mode, pressing and holding the Hold/Set
button for 3 seconds allows you to enter the programming parameter interface. When
thermostat is Off, pressing and holding the Hold/Set button for 5 seconds allows you
to enter the programming parameter interface.
Clock and day of the Week Display.
Cool symbol: When the Cool symbol is displayed, the cooling relay has been activated.
When the Cooling symbol is flashing, it means that the cooling relay is in the set-up
delay process.
Heat Symbol: When the Heating symbol is displayed,the heating relay has been
activated. When the Heating symbol is flashing, it means that the heating relay is in the
set-up delay process.
System Cool Symbol: When the System Cool symbol is displayed, it indicates the
thermostat is in cooling mode.
System Heat Symbol: When the System Heat symbol is displayed, it indicates the
thermostat is in heating mode.

Down button: In heating/cooling mode, the Down button lowers the temperature
setting. When programming, the Down button will be used for changing system
parameters.
Up button: In heating/cooling mode, the Up button raises the temperature setting.
When programming, the Up button will also be used for changing system
parameters.
Cool/Heat/Off button: Press once for Cooling Mode. Press twice for Heating Mode.
Press 3 times to turn Off the thermostat.
Fan button: Switches between fan On and Auto. When fan is On, the fan on your
appliance will remain on. In Auto mode the fan will come on only when heating or
cooling.
Hold symbol: When the Hold symbol is displayed, the Hold button has been activated
and the current temperature will be held and the thermostat will not follow programmed
routine.
Room Temperature Display: Displays the current room temperature.
Temperature Setting Display: Displays the current temperature setting.
Low Battery Warning: When this symbol is displayed replace the batteries with 2 new,
high quality AA batteries.
Fan Symbol: Displays the current mode of the fan.
Program Setting Display: Indicates when the system is in the setting process.

Do not inatall thermostat in the following places:
Close to hot or cold air ducts
In direct sunlight
On an outside wall
In a corner or behind a door
Where there are concealed chimneys or pipes in the wall behind
Select an appropriate location. The temperature of the location should be representative of the building.
5. Thermostat Base Installation
Caution:
Equipment Damage
Hazard
The thermoatat should be installed approximately 4 to 5 feet above the floor.
Select an area with average temperature and good air circulation.
Insert a screwdriver into the slot and pry up
the front part of the panel to open it.
For horizontal mount put one screw left
in the left hole and one screw in the right hole.

6.Wiring
1. If you are replacing a thermostat. take
note of the terminal connections, the
wiring connections may not be color
coded. For example, the Green wire
may not be connected to the G terminal.
2. Loosen the terminal block screws. insert
wires then retighten terminal block screws.
3. Place nonflammable insulation into wall
opening to prevent drafts.
7. Wiring Diagrams
Power supply.
Factory-installed jumper. Remove only when installing on 2- transformer systems.
In heat pump mode, please check the reversing valve to see whether it is in Oor Bposition, and
enter the system to set reversing valve to the position required.
The system is in the electric mode as default setting. If the system is gas or oil, enter the setting
interface in the gas mode.
For 24 VAC common connection when thermostat is used with battery power mode.
Do not over tighten terminal block
screws, as this can damage
terminal block. Keep the thermostat
correctly fitted to the base to avoid
operation issues.
Heat pump changeover valve
energized for cooling
Heat pump changeover valve

Use shielded or non-shielded 18-22 gauge thermostat wire.

(1) COOL/HEAT/OFF: Press the “COOL/HEAT/OFF” button once to turn on the system. The mode will be
cool and “ ” is displayed. The room temperature setting temperature, and clock will be also displayed.
To change to heating mode, press the COOL/HEAT/OFF button a second time and “ ” will be displayed.
Press again to turn off the system and “off ” is displayed.
(2) Setting temperature: When power on, press “ ” or “ ” to set the temperature. Press “ ” to lower
the setting temperature, and press “ ” to raise the setting temperature.
(3) Fan mode: When power is on, press the fan butoon to select fan on, and press a second time to change

9. Mount Thermostat & Battery Installation
Important:
Then it will be working.
You can choose traditiona mode or heat pump mode based on your requirements. When heat pump mode
is set, the compressor will have a 5 minute delay before restarting.
You can choose to have reversing valve on the heat pump work in the heat mode or the cool mode.
In the heat pump mode, please check the recersing valve to see whether it is in O or B position, and
enter the system to set teversing valve to the position you need.
The thermostat has an intelligent recovery function that brings your room to temperature at exactly the
pre-set time by turning on the Heating earlier. Select 1 to activate the intelligent recover function, Select
0 to deactivate the intelligent recovery function. The default setting is “0”.
This function is the control and selection for the heat fan, If you use a gas or oil heating system, Please
choose “GAS” (system controls fan operation). If you use an eletric heating system, please choose
“Electric” (thermostat controls fan operation).
High quality alkaline batteries are recommended. Rechargeable batteries or low quality batteries
may not have a 1-year life span.
Step 1: Align the inner snaps with
the top part of the thermostat.
Step 2: Hang the two hooks of the
front part at 30°right to the snaps.
Step 3: Press in the lower part of the front
display panel to complete the installation.
