heatit ET-7AW Touchscreen Programmable Thermostat
Instruction
The ET-72GW series thermostats control the floor heating system based on built-in weekly program. The weekly program runs in 4 or 2 stages per day, 7 days a week. The default weekly program parameters can satisfy most usage scenarios. If your living habits are different, you can also modify the weekly program parameters in the thermostat or APP. When there is no one in the house, it is recommended to set the temperature down to save energy. Besides, the thermostat has built-in adaptive function. When this function acts, the thermostat heats or stops heating in advance of next stage to bring the room temperature to the set temperature of the next stage. Please note that after turning adaptive on, the thermostat takes a few days to learn the time required.

Ground Fault Circuit Interrupter (GFCI)
This thermostat has a built-in GFCI function that protects people from electric shock. It is very important to check whether the GFCI function is normal or not every month. Here are the check steps:
- Confirm that the thermostat is turned on.
- Press the [Test Monthly] button. If a red light appears in the upper left corner of the thermostat and GROUND FAULT appears on the screen, the GFCI function is normal. If there is no response, it means the function is invalid, please contact the dealer or electrical installer. Note: Do not press and hold the [Test Monthly] button.
- Press the [Reset] button. The red light is off and the screen shows the power off state.
- Press the [Reset] button again. The thermostat is turned on. If in daily use, the red light is on and the screen appears GROUND FAULT. Then you need to check if the ground fault is present by pressing the [Reset] button. If the red light is off and the screen shows the shutdown status, it is nuisance tripping. If not, it means that ground fault has occurred. Please contact your dealer or professional technician immediately.
WiFi connection(Only for ET-72GW、ET-7AW、ET-92GW)
- Step 1: Scan the QR code or download Warmme from APP store/Google browser.
- Step 2: Register and log in with mobile number or email address in the APP.
