Overview

The Uponor Heat and Cool
Thermostat (A3030102) controls
hydronic heating, air conditioning
and a fan. The six-wire thermostat
receives power from the Rh (radiant
heating) and C (cooling) terminals.

These thermostats are power­sharing, meaning they receive power
for operation by sharing voltage
with the connected wiring. This
eliminates any need for a third wire
or batteries, making them simple to
install, wire and service.

Note: Uponor thermostats work
effortlessly with other Uponor
components. However, some
commonly used third-party devices
(e.g., relays, zone valves, etc.) may
have compatibility issues with these
thermostats. If connecting the
Uponor thermostat to a third-party
control device, refer to that device’s
installation instructions for specific
information regarding operation
with power-sharing thermostats. The

ypical Wiring Schematics section on

T
page 5 features the most common
wiring applications. For additional
help, contact Technical Services.

Tools Required

• Small, flat-head screwdriver

• Phillips screwdriver (for
mounting hardware)

• Wire stripper and cutter

Installation

To properly install the thermostat,
refer to the following instructions.

1. Thoroughly read this instruction
sheet to understand the proper
procedures for installation and
operation. Failure to do so could
result in damage to the
thermostat or its connected
equipment, and can also create
a safety hazard.

2. Ensure the function and rating
of the thermostat is suitable for
the application.

3. Only experienced and trained
professionals familiar with low­voltage wiring should attempt to
install the thermostat.

4. Uponor recommends using
18AWG LVT wiring for all
low-voltage connections
(as regulated by local
building c

odes).

Mounting the Wall Plate

The thermostat case can mount to a
standard electrical wall box or most
wall surfaces using suitable
hardware. To properly mount the
wall plate, refer to the following
instructions.

1. Separate the front and back
plates of the thermostat by
gently applying downward
pressure on the front plate to
separate the front plate from
the back plate.

2. Pull the thermostat wire
through the round opening in
the back plate.

3. Place the back plate against the
wall at the desired location to
cover the opening or electrical
wall box.

4. Align the holes of the back
plate to the holes in the wall or
electrical wall box, and attach
the plate with screws. If
mounting the plate to drywall,
use wall anchors and screws.

5. If the wall cavity behind the
thermostat is susceptible to

1. Remove 1⁄4" of wire insulation
from the wire ends. Ensure the
bare wires are clean and free
of corrosion.

2. Route the wires to the terminal
blocks and place the end of
the wires in the correct
wiring locations.

Note: The heat terminals (Rh
and W) are not polarity sensitive.

into place.

Operation

The dynamics of a r
heating system differ from a
typical baseboard or forced-air
heating syst
radiant systems heat the mass
and the objects in the room. The
Uponor thermostat uses optimized
control logic to control radiant
systems. Refer to the following

Heating Mode

When the room temperature falls

0.5°F (0.25°C) below the desired
room setting, the control devices wired
to the thermostat activate. When the
room temperature rises 0.5°F (0.25°C)
above the desired room setting, the
control devices wired to the thermostat
deactivate.

Cooling Mode

When the room temperature rises to
1°F (0.5°C) above the desired room
setting, the control devices wired to
the thermostat activate. When the
room temperature falls 1°F (0.5°C)
below the desired room setting, the
control devices wired to the thermostat
deactivate.

Automatic Mode

The thermostat automatically switches
between heating and cooling modes
based on the heating and cooling
setpoints. (The cooling setpoint must
be greater than or equal to the heating
setpoint.) When the thermostat is in
automatic mode, the cooling mode
icon (snowflake) flashes when the
cooling system is active; the heating
mode icon (floor with tubing) flashes
when the heating system is active.
