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.

Program Schedule
You can program four time periods each day, with different settings for weekdays
and weekends. We recommend the pre-sets (shown in the table below), since they
can reduce your heating expenses.
Wake - Set to the time you wake up and the
temperature you want during the morning, until
you leave for the day.
Away - Set to the time you leave home and the
temperature you want while you are away (usually
an energy-saving level).
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).
NOTE: To temporarily or permanently override any
of the above program schedules, see page 5.
Depending on which temperature control mode the thermostat is configured
for (see page 2), you will be programing either air or floor temperature. Floor
temperature will be indicated with FLR text above the actual temperature value.
