Installation Instructions
ProSeries
Welcome!
T6 Pro Hydronic Programmable Thermostat can be used
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/
TEMP.
NOTE: To set the thermostat temperature
control mode, go to “Installer setup (ISU)”
on page 7.

UWP Mounting System installation
Use 3x supplied
screws #8 11/2”
5. Before starting, turn the power off
at the breaker box or switch. Open
package to find the UWP. See Figure 5.
6. Position the UWP on wall. Level and
mark hole positions. See Figure 6.
Drill holes at marked positions, and
then lightly tap supplied wall anchors
into the wall using a hammer.
‒Drill 7/32” holes for drywall.
7. Pull the door open and insert the wires
through wiring hole of the UWP. See
Figure 7.
8. Place the UWP over the wall anchors.
Insert and tighten mounting screws
supplied with the UWP. Do not
overtighten. Tighten until the UWP
no longer moves. Close the door. See
Figure 8.

NOTE: If Optional Cover Plate is not
required, see “UWP Mounting System
installation” below.
Use the Optional Cover Plate when:
•Mounting the thermostat to an
electrical junction box
•Or when you need to cover paint gap
from old thermostat.
1. Separate the Junction Box Adapter
from the Cover Plate. See Figure 1.
2. Mount the Junction Box Adapter to
the wall or an electrical box using
any of the eight screw holes. Insert
and tighten mounting screws
supplied with Cover Plate Kit. Do not
overtighten. See Figure 2. Make sure
the Adapter Plate is level.
3. Attach the UWP by hanging it on the
top hook of the Junction Box Adapter
and then snapping the bottom of the
UWP in place. See Figure 3.
4. Snap the Cover Plate onto the
Junction Box Adapter. See Figure 4.

Power options
Insert Rand Cwires into
designated terminals for primary
AC power (C terminal is optional
if batteries are installed, but it is
recommended). Remove wires by
depressing the terminal tabs. Insert AA batteries for primary or backup
power. Match the polarity of the batteries
with the + / – marks inside the battery
compartment.
Set R Slider Tab.
• Boiler, hot water valve circuit, or hot water
relay panel wires to Rand W. If the same
transformer is providing common to power
the thermostat, wire the transformer
common to Cand leave the R slider tab in
the up position (1 wire). If a transformer
that is not powering the heating equipment
is used to power the thermostat display,
set the R slider tab to the down position
(2 wires). Wire the heat circuit to Rand W,
then wire the separate transformer to Rc
and C.
NOTE: Slider Tabs for U terminals should be
left in place for this thermostat model.

Floor temperature sensor installation
T6 Pro Hydronic thermostat is compatible
with the following 10K ohm floor temperature
sensors: AQ12C20 and 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.
Recommended floor temperatures
settings
Recommended maximum floor temperature
is 90 °F (32 °C) for most floor covering types
except wood. Suggested maximum floor
temperature for wood floor is 85 °F (29.5 °C).
Freeze protection temperature for garages and
basements is suggested to be set between
4145 °F (57.2 °C).

Notes
370 Heating Cycle Rate
(Cycles per hour) 1 - 12 This ISU allows you to limit the maximum number of times the system can cycle in a 1 hour period
measured at a 50% load. For example, when set to 3
CPH, at a 50% load, the most the system will cycle
is 3 times per hour (10 minutes on, 10 minutes off).
The system cycles less often when load conditions
are less than or greater than a 50% load. The
recommended (default) cycle rate settings are below
for each heating equipment type selected:
Hot Water Radiant Heat = 3 CPH; Hot Water
Radiant Floor Heat in A or AF mode = 1CPH; Hot
Water Radiant Floor Heat in F mode = 3CPH; Steam
= 1CPH
