Check Sensor Type
If reusing an old embedded floor sensor, match the correct NTC sensor type in advanced settings.
Common Sensor Types
10K
12K
15K
Included 15 ft Sensor
A mismatched floor sensor type can cause inaccurate temperature readings, poor heating control, or error codes.

Understanding Sensor Modes
Floor Sensor Mode
Uses the floor sensor to control floor temperature. Common for tile, stone, and floor warming applications.
Room Sensor Mode
Uses the thermostat’s internal room sensor to control room air temperature.
Dual-Sensor Mode
Uses room temperature for comfort control while using the floor sensor as a floor temperature limit.
Load and Sizing Reminder
Before installing the thermostat, calculate the total load of your electric floor heating system.
Voltage: 120V or 240V
Total wattage
Total amperage
Circuit rating
GFCI protection
Wiring compatibility
Do not exceed the thermostat’s rated load. If your floor heating system exceeds the load rating, a different control method or contactor-based installation may be required.
Schedule Settings
5+1+1 Schedule
Useful if you want one schedule for weekdays, one schedule for Saturday, and one schedule for Sunday.
7-Day Schedule
Useful if you want each day programmed separately.
Six Periods Per Day: The six daily periods allow you to set different temperatures for daily routines such as waking, leaving, returning, and sleeping.
Adaptive Recovery / Early Start
Adaptive recovery helps the floor reach the target temperature by the scheduled time. For example, if you set the floor to be warm at 7:00 AM, the thermostat may start heating earlier so the floor is already warm at 7:00 AM.
This is normal behavior and can be adjusted in settings if you prefer strict schedule timing.
Basic Installation Overview
YeloDeer Smart WiFi Electric Floor Heating Thermostat should be installed according to the product manual and local electrical code.

- Confirm the floor heating system voltage: 120V or 240V.
- Confirm the heating load is within the thermostat rating.
- Confirm the floor heating circuit has proper GFCI protection.
- Remove the old thermostat if replacing one.
- Identify line, load, and sensor wires.
- Connect the thermostat according to the wiring diagram.
- Connect the included 15 ft floor sensor or compatible existing sensor.
- Mount the thermostat into a standard electrical box.
- Restore power and follow setup instructions.
- Select sensor mode and sensor type if needed.

Important Installation Notes
Turn Off Power
Always turn off power at the breaker before wiring or inspecting connections.
Confirm Voltage
Confirm whether your floor heating system is 120V or 240V before installation.
Check Load
Do not exceed the thermostat’s rated load.
Use GFCI Protection
This thermostat does not include built-in GFCI. Electric floor heating requires GFCI protection according to local code.
Match Sensor Type
If reusing an old floor sensor, confirm the NTC resistance type in advanced settings.
Use Qualified Help
Installation should be performed by a qualified electrician if you are not familiar with electrical wiring.
Floor Sensor Installation
The included 15 ft floor sensor should be placed according to your floor heating system instructions.
Good Sensor Placement
For new installations, the floor sensor is usually placed between heating cable runs and positioned to measure floor temperature accurately.
Avoid These Issues
Do not place the sensor touching, crossing, or too close to a heating cable unless the floor heating system instructions specifically allow it.
Sensor Type Reminder
If the displayed temperature seems very inaccurate, or if an E2 error appears, check the floor sensor connection, sensor wire damage, sensor resistance type, advanced sensor settings, and whether the sensor is compatible.
Using the Smart Life App
Remote Temperature Control
Adjust the set temperature from the Smart Life app when connected to 2.4GHz WiFi.
Schedule Adjustment
Change daily heating schedules from the app for easier comfort planning.
Status Checking
Check thermostat status and settings without using the touchscreen directly.
WiFi is optional for basic thermostat operation. The thermostat can still control floor heating locally from the touchscreen.
Voice Control
This thermostat can work with Amazon Alexa and Google Assistant for basic compatible voice commands. Voice control is a convenience feature for electric floor heating temperature adjustment. This thermostat is not intended to act as a general smart home hub.
