Installation manual

12 Underfloor Heating
3.3.4.4 Circulation pump relay
The Uponor Control System can operate a circulation pump
on heating/cooling demand. The pump will stop when there is
no heat or cooling demand.
Example of an installation:
The controller controls the circulation pump via connection on
terminal block (dry contact). There is no power for the pump
in the box, just the dry contact.
3.3.5 Connecting the controller to the mains
WARNING
See the circulation pump supplier
documentation before performing the
connection.
The electrical circuits of the pump must be
protected by a maximum 6A circuit-breaker.
1 Ensure the power is disconnected
2 Open 230V compartment and fix cover to hanger
3 Connect "L" wire from/to pump via relay
4 Close 230V compartment
The pump runs when at least one actuator is active.
During actuator exercise, the pump continues to
work normally.
1
Check that the wiring is complete (actuators,
thermostats, pump, timer)
2 Check that the 230V compartment is closed
3 Connect the plug to the mains
