Connecting A Heating-Cooling Switch; Connecting A Circulation Pump; Connecting A Boiler - Uponor UponorControl System Installation And Operation Manual

See section 4.4.4 Uponor Controller C-35 with four thermostats
and timer for a connection example.
4.3.6 Connecting a heating–cooling switch
If the installation is equipped with a cooling unit, the Uponor
Control System Wired can be run through a heating–cooling
switch.
The controller heating–cooling input operates with the
connection of a dry contact that can be realized with, for
example, a relay controlled by an additional regulation system or
a two-position switch. See figure below.

B Heating–cooling switch realized with a relay
C Circuitry with timer controlling the relay C
D Alternative heating–cooling switch using a manual
To connect a heating–cooling switch 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. Connect the heating–cooling switch to positions 11 and 12,
.
4. Tighten the screws of the cable clamps to fix the heating–
cooling cable.
See section 4.4.5 Uponor Controller C-35 with four thermostats,
timer and heating–cooling switch
4.3.7

Connecting a circulation pump

Uponor Control System Wired can operate a circulation pump on
heating–cooling demand. The pump will stop when there is no
heat or cooling demand.
The controller controls the circulation pump via connection on
terminal block (dry contact). There is no power for the pump in
the box, only the dry contact.
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.

for a connection example.
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.
NOTE!
There is no power in the controller to supply the
pump. The pump connector in the controller provides
only a dry contact to switch off and on the power
connection to the 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.
