Power
WARNING
The Uponor Control System uses 50 Hz 230 V AC power.
In case of emergency, immediately disconnect the
power.
Limitations for radio transmission
The Uponor Control System uses radio transmission. The
frequency used is reserved for similar applications, and the
chances of interference from other radio sources are very low.
However, in some rare cases, it might not be possible to
establish perfect radio communication. The transmission
range is sufficient for most applications, but each building
has different obstacles affecting radio communication and
maximum transmission distance. If communication difficulties
exist, Uponor can support the system with accessories, such as
repeaters, for solving exceptional problems.
Technical constraints
• To avoid interference, keep installation/data cables
away from power cables for more than 50 V.
• The electrical circuits of the boiler and the pump
must be protected by a circuit breaker rated at 6 A or
below.
Disposal
The Uponor Control System consists of various recyclable
components. Uponor would be grateful if the components
(batteries, plastics, and electric or electronic parts) are sorted
and disposed of at a suitable recycling centre.

Refer to the installation preparation guidelines (see section
2.1 on previous page), and use the following guidelines when
positioning the controller:
• Position the controller just above the manifold. Check the
position of the 230 V power outlet.
• Check that the cover of the controller can be removed
easily.
• Check that connectors and switches are easily accessible.
The controller must be attached horizontally on a wall. There is
a risk of overheating if there is a high ambient temperature or if
the controller is attached vertically or on a horizontal surface, as
shown in the illustration below.
3.1 Install controller antenna
The antenna can be attached to the back of the controller or
to the wall. If the controller is installed inside a metal cabinet,
the entire antenna must be outside the cabinet, as shown in the
illustration below.
Attach antenna to controller back
The illustration below shows the antenna attached to the back
of the controller using the 0.3 m antenna cable.

Connect actuators to controller
Each thermostat can control one or more channels. To
simplify installation and maintenance, Uponor recommends
that actuators controlled by the same thermostat be wired in
sequence to the channels.
Identify the room supplied by each loop on the manifold
and determine which channel it must be connected to.
3.4 Optional: connect heating/cooling input
If the system is equipped with a cooling unit (requires additional
products), the Uponor Control System can manage the heating/
cooling switch input with the controller.
The heating/cooling input is controlled by a dry contact that
functions as either an auxiliary control system or two-position
relay.
• When the relay is open, the system is in heating mode.

3.5 Optional: connect pump management
The Uponor Control System can operate a circulation pump,
which stops when there is no demand for heating or cooling.
See the circulation pump supplier documentation and
the relevant Uponor wiring diagram before performing
the connection.
Uponor Controller C-55/56 cannot supply power source
for the pump.
Uponor Controller C-55/56 uses a dry contact connection on
the terminal block to control the circulation pump.
The electrical circuits of the pump must be protected by a
circuit breaker with a maximum rating of 6 A.
The illustration below shows how to connect circulation pump
management to the controller:
To connect circulation pump management:
1 Ensure the power is disconnected.
2 Open the 230 V compartment and attach the cover to the
hanger.
3 Connect the L wire from/to the pump via the relay.
4 Close the 230 V compartment.
A pump for all manifolds and controllers can be connected to
the closest controller.
If separate pumps are used for each manifold, each pump can
be connected to be run by its own controller, as shown in the
illustration below.
Shared pump Individual pump
3.6 Connect controller to AC power
To connect one Uponor Controller C-55/56 to AC power:
1 Check that the wiring is complete for the actuators and
antenna.
2 Check that the 230 V compartment is closed.
3 Connect the controller plug to the AC power.

3.7 Test actuators
Uponor Controller C-55/56 manages the temperature set point.
When a temperature change occurs, the actuator opens or
closes the valve to adjust the heat supply.
To test the actuators:
1 Press the button of the selected channel.
• The LED comes on, which means that the controller
receives a signal and powers the actuator on the
selected channel. The time for actuator opening is about
5 minutes.
• If the LED does not come on, then refer to the
troubleshooting section.
2 Press the test button twice to end the actuator test or wait
for 10 minutes for the system to end the test.

4. Install Uponor Thermostats
Label room thermostats
Label the thermostats with the channel numbers they are to
control, for example, 02, 03. For a system with Uponor Interface
I-75/76 and several controllers, add the ID of each Uponor
Controller C-55/56, for example, 1.02, 1.03, 2.02, 2.03.
For Uponor Thermostat T-54 Public, add information for floor or
outdoor sensors when applicable.
The illustration below shows where to label the thermostats.
Insert batteries
All thermostat types use two alkaline 1.5 V AAA batteries.
Ensure that the batteries are correctly inserted in the
thermostats.
Locate thermostats
The Uponor Wall frame can be used to hide marks on the wall or
the wall box if necessary.
Refer to the installation preparation guidelines (see section
2.1 Prepare for installation on page 14) and use the following
guidelines to locate all thermostats:
• On an interior wall.
• Away from any source of humidity.
• Away from any source of heat, such as television, electronic
equipment, fireplace.
• Away from direct sunlight.
• Away from water splashes.
4.1 Optional: connect Thermostat T-54 Public to
external sensor
Uponor Thermostat T-54 Public has a terminal for connecting
an external sensor, which can be a floor sensor or an outdoor
sensor (used with Uponor Interface I-75/76 to display the
outdoor temperature).
Set switches for external sensors
The configuration switches must be set according to the way in
which the thermostat is used, as shown in the illustration.
The table below describes how to set the switches shown in
the illustration above, according to the way Uponor Thermostat
T-54 Public is used.

Example installation with floor sensors
The example below shows an installation of thermostats in a
room with floor sensors. Uponor Thermostat T-54 Public 01 and
10 are connected to floor sensors.
In the example, Uponor Thermostat with display T-75 #01
controls channels 01a, 01b, 02a, and 02b. Uponor Thermostat
T-54 Public communicates floor temperature to the controller.
Uponor Thermostat with display T-75 #03 controls channels 03
and 04.
If the external sensor thermostat is registered to a
channel used by a room thermostat, then the room
thermostat must be registered before registering the
external sensor thermostat. Thermostats with floor
sensors have a higher priority than room thermostat.
Wire external sensor to Thermostat T-54 Public
1 Connect cable from the floor or outdoor sensor (non-
polarized).
2 Tighten the screws to fix the cable wires
For accurate temperature: attach the outdoor sensor
on the north side of the building where it is unlikely to
be exposed to direct sunlight. Do not place it close to
doors, windows, or air outlets.
Adjust floor sensor settings
The Uponor Thermostat T-54 Public sends the external sensor
values to the controller. Temperature settings can be adjusted by
using the potentiometer, as shown in the illustration below.
To adjust floor minimum or maximum temperature:
1 Select the required temperature with the potentiometer.
