Floor/Slab Sensor (T10+ only)

The T10+ Smart Thermostat can be used with a floor/slab
sensor to control the ambient air temperature or floor
temperature or both. You can choose among the following
temperature control modes.
A mode: Controls and displays the ambient air temperature
only.
F mode: Controls and displays the floor temperature only
using an external floor temperature sensor. This control mode
is suitable for areas such as bathrooms where floor
temperature could be scheduled to be warm only during
occupied, morning and evening periods.
• Floor temperature is indicated by "FLR" above the
actual floor temperature.
• Actual ambient air temperature could also be
displayed in the Thermostat MENU/TEMP. AF
mode: 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 a way to enhance comfort and to protect the floor
covering at the same time.
• Actual floor temperature could also be displayed in
the Thermostat MENU/ TEMPERATURES.

NOTE: To set the thermostat temperature control mode, go
to "Installer setup (ISU)" section and see settings
(1055 & 5120-5170).

Floor Temperature Sensor Installation
T10+ Thermostat is compatible with the following 10K ohm
floor temperature sensors: AC112-01.

The floor temperature sensor needs to be installed mid way
between the piping to ensure proper temperature reading (not
over or right next to piping). Example: For a 12" pipe spacing
install the sensor 6" away from the piping and ensure the
sensor is vertically centered.
We recommend installing the floor temperature sensor inside
of min. 0.5'' PEX pipe. This simplifies future sensor
replacement, if required.
In a small room, position the sensor in the center of the floor.
In larger rooms, ensure the sensor is at least 7 feet from the
wall.
