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.

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.

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.
