Wiring the
Thermostat
The following steps outline how
to wire the thermostat.
Note: All wiring must comply
with local electrical codes
and specifications. Uponor
recommends 18 AWG LVT or
similar wire for all thermostat
connections. Strip all wires to
¼" (6.3 mm) to ensure proper
connection to thermostat
terminal blocks. If an optional
sensor is used (e.g., a slab
sensor), run a single-pair,
18 AWG wire from the sensor
to the control.

Tools Required

• Small, flat-head screwdriver
• Phillips screwdriver
• Wire cutter and stripper
Caution: To prevent
damage to the thermostat,
do not connect it to 24-volt
control systems or devices
other than the Digital Zone
Control Module (DZCM).

Power and Data Wiring

1. Refer to the DZCM Installation
Guide for wiring to the DZCM.
2. Run a single-pair, 18 AWG LVT
wire from the DZCM to the
thermostat.
3. Attach the wires to the Pwr/
Comm terminals shown in
Figure 2-14.
Note: Be sure to observe the
thermostat's polarity and wire
color. Use the red wire to
connect the positive terminal on
the thermostat to the positive
terminal on the controller.

Placing the
Slab Sensor
The following steps outline how to
install a slab sensor.
1. Place the slab sensor between
two PEX tubes in the floor.
2. If the floor is wood construction,
place the sensor as close to
the floor surface as possible.
If the floor is concrete or like
construction, place the sensor
no deeper than the mid-point
of the slab.
3. Uponor recommends placing
the sensor wire in a conduit
for easy replacement. Ensure
the sensor is in direct contact
with the floor material (wood,
concrete, gypcrete, etc.).

Wiring the Slab Sensor

Connect the two wires from the
sensor to the slab sensor terminals
on the thermostat as shown in
Figure 2-15. In this case, polarity
does not matter.
