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, AF mode; main screen

F mode; main screen

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
