Understanding Sensor Modes
This thermostat supports multiple sensing modes so you can control your floor heating based on your application.
Floor Sensor Mode
Uses the floor sensor to control floor temperature.
This is commonly used for tile, stone, and floor warming applications where protecting the floor temperature is important.
Room Sensor Mode
Uses the thermostat’s internal room sensor to control room air temperature.
This may be suitable when the floor heating system is used as part of room temperature control.
Dual-Sensor Mode
Uses room temperature for comfort control while using the floor sensor as a floor temperature limit.
This is useful when you want room comfort while also preventing the floor from overheating.
Load and Sizing Reminder
Before installing the thermostat, calculate the total load of your electric floor heating system.
Confirm:
• 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
The thermostat supports 5+1+1 and 7-day scheduling.
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.
