3Description
Uponor Control System Wired is a management system for
underfloor heating and cooling installations. Comfort, userfriendliness and temperature control for each individual room of
a home can be combined through the use of thermostats or floor
temperature sensors.
3.1 System overview
Uponor Control System Wired consists of a controller,
thermostats, actuators and an optional timer. The controller
manages the operation of the actuators when the thermostats
detect a demand for heating or cooling.
Uponor Control System Wired is controlled by different types of
thermostats. Designed for maximum comfort, the thermostats
communicate with the controller by non-polarized two wired
cables. It is possible to mix the different types of Uponor wired
thermostats in the same installation.
3.2 Example of a system
Pos. Description
A Uponor Thermostat T-36 wired with the option of
adding a floor sensor
B Uponor Thermostat Public T-33 wired with the option
of adding a floor sensor
C Uponor Thermostat T-37 wired with the option of
adding a floor sensor
D Uponor Controller, 6 Channels C-33 Wired or
Uponor Controller, 12 Channels C-35 Wired
The floor sensor can be used for maximum or
minimum limitation of the floor temperature,
regardless of the room temperature. The floor sensor
can be used with Uponor thermostats T-33,T-36,
T-37 and T-38
For example, the maximum limitation can protect a
sensitive floor covering from exposure to too high
temperature when there is a high heating demand.
The minimum limitation can keep a tiled floor warm
even when there is a no general demand for heat
supply to the room.
NOTE:
Auto-balancing is now possible with Uponor Control
System Wired. If the auto-balancing function is used,
it is recommended to use it for the whole system.
Uponor Digital Thermostats T-36 and T-38 are
equipped with the auto-balancing function.

3.3.4 Uponor Actuators
Uponor actuators are mounted on top of the valves of the
manifolds
When the thermostat senses that the temperature has fallen
below the setpoint, the controller sends a signal to the actuator
to open the valve. The indicator window on the actuator turns
bright.
When the thermostat senses that the temperature has risen
above the setpoint, the controller sends a signal to the actuator
to close the valve. The indicator window on the actuator turns
dark.
3.4 Function
Uponor Control System Wired is used to control an underfloor
heating system in a house. It can also control a combined heating
and cooling system.
The thermostats that are connected to the controller control the
actuators that are mounted on the manifolds.
For example in a heating system, if a thermostat senses that the
temperature in a room falls below the setpoint, then the
controller regulates the actuators to open more and increase the
heat flow in the floor pipes in the room.
If a thermostat senses that the temperature in a room rises above
the setpoint, then the controller regulates the actuators to close
more and decrease the heat flow in the floor pipes in the room.
3.4.1 Comfort and economy modes
If a timer is connected to the controller, it is possible to regulate
the temperature between two different temperatures, that is
comfort mode and economy mode. See example below.
The diagram shows that the system delivers heating in comfort
mode in the morning and afternoon, but the system enters
economy mode during night and in the middle of the day, when
the house normally is empty.
The controller can use two different timer patterns to regulate
the temperature in different ways in different rooms.
A Actuator has closed the valve – dark indicator
B Actuator has opened the valve – bright indicator

controlled from the same thermostat.
The next thermostat, #05, controls the actuators on rows 05 to
11 and thermostat #12 controls the actuator on row 12.
The controller senses automatically where the thermostats and
the actuators are connected, this is called auto linking.
Auto linking rules
In order to make the auto linking of the controller to work
correctly, the following restrictions apply:
• Actuators must not be connected in parallel
• Actuators must not be linked with jumper cables
• The first thermostat must always be connected to the
controller on connector row 01
• There must never be any empty connector row between
groups of thermostats and actuators
• Empty connector rows are only allowed after the last actuator
in the last group of thermostat and actuators, that is in the
end of the connector field
A Cable entries and cable clamps for thermostats
B Cable entries for actuators

To connect a circulation pump to the controller, do this:
1. Follow the general instructions in section 4.3.1 for
connecting devices to the controller.
2. See the wiring diagram on the foldout page for connector
positions.
3. Ensure the power is disconnected from the controller and the
circulation pump.
4. Open the lower lid (A) of the 230V compartment in the
controller and fix it to the latch (B)on the upper part of the
lid.
5. Connect the circulation pump to connectors labelled PUMP.
6. Tighten the screws of the cable clamps to fix the pump cable.
7. Close the lid and tighten the fixing screw.
4.3.8 Connecting a boiler
If the Uponor Controller C-33or C-35 includes a boiler relay, it
can be used to either directly fire the heat source or power open
a two port motorised zone valve positioned on the flow to the
underfloor heating manifold. If the relay is used to power open a
zone valve then the volt free auxiliary contacts on the zone valve
should be used to fire the heat source.
Alternatively, the boiler relay can be used to send a demand
signal to an electrically operated water temperature controller.
The additional contacts on the water temperature controller
should then be used to fire the heat source.
To connect a boiler to the controller, do this:
1. Follow the general instructions in section 4.3.1 for
connecting devices to the controller.
2. See the wiring diagram on the foldout page for connector
positions.
3. Ensure the power is disconnected from the controller and the
boiler.

boiler. The boiler connector in the controller provides
only a dry contact to switch off and on the power
connection to the boiler.
NOTE!
The timer is not available for the 6-channel
controller.
NOTE!
The economy mode (ECO) is not available for the 6channel controller.
NOTE!
When connecting thermostats and actuators to the
Uponor Controller, the auto-linking rules must always
be followed strictly. See section 4.3.2
Auto linking,
page 11
Any disregard to follow the auto linking rules will
result in erroneous function of the Uponor Controller.
