Temperature control modes

Your T6 Pro Hydronic Programmable Thermostat can be set to operate in one of 3 different control modes. These settings determine which temperature is measured, controlled and displayed on the thermostat home screen. Each thermostat in your home can be set to a different control mode. Please ask your local heating professional which control mode is used for you to better control the Thermostat.

A mode (Air temperature only): Controls and displays the ambient air temperature only.

F mode (Floor temperature only): Controls and displays the floor temperature only using an external floor temperature sensor. This control mode is typically used in areas such as bathrooms where floor temperature could be scheduled to be warm only during occupied, morning and evening periods.

• Actual floor temperature is indicated by "FLR" text above the actual floor temperature value.
• Floor temperature setpoint is not displayed until you press or for setting it.
• Actual ambient air temperature could also be displayed in the thermostat MENU/ TEMP.

AF mode (both Air and Floor temperatures): Controls and displays the ambient air temperature as well as maintains the floor temperature within desired floor temperature limits using an external floor temperature sensor. Setting the minimum and maximum floor temperature limits is done by your local heating professional and is a way for you to enhance the comfort and to protect your floor covering at the same time.

• Minimum floor temperature limit will override the air temperature in this mode, and if set too high, may overheat the room. Please contact your installer if this occurs.
• Actual floor temperature could also be displayed in the thermostat MENU/ TEMP.

Home - Set to the time you return home and the temperature you want during the evening, until bedtime.
Sleep - Set to the time you go to bed and the temperature you want overnight (usually an energy-saving level).

Adaptive Intelligent Recovery

Over time, the Resideo T6 Pro Thermostat "learns" how long it takes your system to reach the temperature you want. It turns on the heating system earlier to make sure you're comfortable at the time you expect.

Battery replacement

Batteries are optional (to provide backup power) if your thermostat was wired to run on AC power when installed. If your thermostat was not wired to run on AC power, then batteries are required.

Install fresh batteries immediately when the low battery icon appears. The icon appears about two months before the batteries are depleted.
Even if the low battery icon does not appear, you should replace batteries once a year, or before leaving home for more than a month.
If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory, and do not require battery power.

NOTE:When replacing batteries, alkaline batteries are recommended.

When the low battery warning appears, press gently to loosen the thermostat and then carefully pull it from the wall mount.
