Uponor Control System - Installation Manual 9
Controller heating / cooling input
Should your system include a cooling unit, it is possible to
manage the Uponor Control System with the help of a
heating / cooling switch input.
The contact may be operated in different ways: timer,
ancillary control system, 2 position switch.
The heating / cooling input operates with the connection of a
dry contact.
• When the contact of the relay is open, the system is in
heating mode.
• When the contact of the relay is closed, the system is in
cooling mode.
Circulation pump relay
The Uponor Control System can operate a circulation pump
on heating/cooling demand. The controlled use of a
circulation pump improves the efficiency and responsiveness
of the underfloor heating.
Example of an installation:
The controller controls the circulation pump via connection on
terminal block (dry contact).
WARNING
Do not apply voltage to the controller heating /
cooling input. Damage to the Uponor Control
System will occur.
