1. Introduction
A simple, easy to use programmable thermostat has the features you want, such as a large touch-screen display and Smart Response Technology. You set it up to adjust the temperature when you are away or asleep-times when you don’t necessarily need to heat or cool your home to optimum comfort-and your HVAC equipment and heat pump runs less.
It automatically adjusts the heating/cooling of your home, so you’re comfortable at your programmed times. With Auto Change from Heat to Cool, the switch from heating to cooling is automatic.

5. Before wiring and installing
Your thermostat can be mounted horizontally on the wall or on a 4 in. x 2 in. (101.6 mm x 50.8 mm) wiring box.
How to select the location?
Install your thermostat about 5ft.(1.5m)above the floor in an area with good air circulation at average temperature.
Don’t install your thermostat where it could be affected by:
-Drafts or dead spots behind doors and in corners.
-Hot or cold air from ducts.
-Radiant heat from sun or appliances.
-Concealed pipes and chimneys.
-Unheated (uncooled) areas.
Step 1. Keep the electricity off.
Step 2.Remove the mounting plate. See fig1.
Step 3. Complete the wiring according to the wiring diagram and select the appropriate hole mounting screws. See Fig 2.
Step 4.Check whether the wiring is correct and look for the correct direction of the thermostat display panel. See Fig 3.
Step 5. Press the thermostat back onto the mounting plate to complete the installation.
6. Operation
Press and hold 
for 3 seconds when thermostat is off. The device will enter the pairing mode.
The backlight will be on and the 
will be flash one time per spec in the pairing mode. This process will last 90 seconds.
Press 
to turn the thermostat on/off.
Press 
to select the mode AUTO, COOL, HEAT, OFF, EMER.
HEAT: Thermostat controls the heating system.
OFF: Both heating and cooling systems are off.
COOL: Thermostat controls the cooling system.
AUTO: Thermostat automatically changes between heating and cooling operation, depending on indoor temperature.
EMER: Emergency heat cycles to maintain temperature. Compressor is locked out (used only for 2H/1C or 3H/2C heat pump systems) and auxiliary heat turns on as second stage if needed.
Press 
to set the Permanent Hold, Temporary Hold, using Schedule and hold until (holiday). The functions will appear on the screen.
Permanent Hold –Manual: In this mode, press 
to set temperature by manual.
Temporary Hold: During using schedule or in this mode, press to set the temporary temp. It will be valid till the start time of the next scheduled period.
Using Schedule: 7days a week, four periods programmable daily.
Holiday Mode: Changes temperature setting for a designated number of days.
Press 
till the min of time will flashes;
Touch the icon to set your minute;
Then press , the hour of time will flash; touch the icon to set your hour;
Then press , the week of time will flash; touch the icon to set your week;
Press four times in a row. (You can see 
and 
）
Use the arrows to adjust the time for the 1st period (Get Up)
Press the icon then use the arrows to set the temp. for the 1st period. Repeat this process for periods 2-4.
Get Up-Period when you awaken and want your home at a comfortable temperature.
Get Out – Period when you are away from home and want an energy-saving temperature.
Go Home- Period when you return home and want your home back to a comfortable temperature.
Sleep-Period when you are asleep and want an energy saving temperature.
| Schedule Period | Time | Set points | |
|---|---|---|---|
| Heat | Cool | ||
| Get Up | 6:00 AM | 72℉（22℃） | 72℉（22℃） |

8. Wiring Diagrams
Notes
1.If there is one power at your home, please connect C and Rc in the upper right corner as the wirings. And ignore J1 and J2 which has been short-circuited at the factory in the lower left corner.
2.If there are two powers at your home, please connect C, Rc and Rh in the upper right corner. And disconnect J1 and J2 in the lower left corner.
3.If there is no C wire at your home, please run a new cable from the furnace to your thermostat before installation.
Notes
You can connect C and Rh in the upper right corner as the wirings for power.
And ignore J1 and J2 which has been short-circuited at the factory in the lower left corner.
