RADIANT HEATING SYSTEMS
HEAT AND COOL
THERMOSTAT
INSTRUCTION SHEET
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 power-
sharing, 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
Typical Wiring Schematics section on
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 low-
voltage wiring should attempt to
install the thermostat.
4. Uponor recommends using
18AWG LVT wiring for all
low-voltage connections
(as regulated by local
building codes).
Placing the Thermostat
Thermostat placement is extremely
important. Install the thermostat
approximately five feet (1.75
meters) above the floor on a
smooth, flat surface. Avoid
mounting the thermostat in the
following locations.
• Near or around windows
• On outside walls
• Near fireplaces
• In the corner of a room
• Behind doors
• On interior walls susceptible
to solar gains
• Near stoves, lamps,
televisions, etc.
• Damp areas
