Uponor Control System - Installation Manual 11
3.3.4 Installation of the options
Different options can be added to the Uponor control system
to enhance its features, optimize your comfort and save
energy.
3.3.4.1 Timer
The Uponor control system can be equipped with a timer to
add energy-saving features and define independent zones.
The timer has two programming zones. Each offers four
programming options, including one that can be personalized,
thus enabling different programmes to be created for each
day of the week.
3.3.4.2 Floor sensor
The floor sensor can be used for maximum or minimum
limitation of the floor temperature, regardless of the room
temperature. It can only be used with the Thermostat Public
T-33 and Thermostat T-37. For example, the maximum
limitation can protect a sensitive floor covering from exposure
to too high temperature when there is a high heat demand.
The minimum limitation can keep a tiled floor warm even
when there is a no general demand for heat supply to the
room. The minimum limitation should not be set to a value
higher than the required room temperature.
3.3.4.3 Controller heating / cooling input
If your installation is equipped with a cooling unit, the Uponor
control system can be run through a heating / cooling relay.
The controller heating / cooling input operates with the
connection of a dry contact.
The contact's control can be either an additional regulation
system or a two-position switch.
Connect the heating / cooling relay between terminals 11
and 12 of the controller (symbol ).
Example of wiring:
To configure the controller in Heating / Cooling mode, press
the push-button on the controller to switch between modes:
• The LED is red for Heating mode.
• The LED is green for Heating / Cooling mode.
WARNING
Mains supply 230VAC 50Hz
Disconnect the 230V mains before installing or
changing the device wiring.
