Operating Uponor Control System Wired
The Uponor Control System Wired controls the floor heating/
cooling installation according to customer needs. Temperatures
are adjusted with thermostats located in each room.
8.1
Principle of operation
As soon as the temperature measured at a thermostat is lower
(heating mode) or higher (cooling mode) than the setpoint
temperature, it sends this information to the controller, which
opens the actuators for this room. Once the set temperature is
reached, this information is sent and the actuators are closed.
8.2
Normal operation without optional timer
When the system is running in normal mode:
In Heating mode, the actuators are open when room
temperatures are lower than the temperatures set on the
thermostat.
In Cooling mode, the actuators are open when room
temperatures are higher than the temperature set on the
thermostat.The actuator position can be seen in the small
windows of the actuators.
8.3
Operation with optional timer
The use of an optional timer optimizes the installation and
conserves energy.
For information about operating the timer, see section
Operating Uponor Timer I-36, page
8.4
Setting analog thermostats
The room temperature set point can be adjusted with a dial on
Uponor Thermostats T-34, T-35, and T-37. See sub-sections
below.
The room temperature set point can be adjusted with a
potentiometer on Uponor Thermostat T-33. This requires that
the cover is removed, see section
controller, page
19.
The floor temperature set point can be adjusted with a
potentiometer on Uponor Thermostats T-33 and T-37. This
requires that the cover is removed. See section Thermostat
installation.
8.4.1
Changing the room temperature setpoint
To change the thermostat setpoint:
1. Turn the dial clockwise to get a higher temperature setpoint.
2. Turn the dial counter-clockwise to get a lower temperature
setpoint.

Setting minimum and maximum temperature
limits
It is possible to set the minimum and maximum limits of the
temperature adjustment. Inside the dial there are two plastic
devices that can be set to limit the turning of the dial. See
illustrations below.
•
The default temperature setpoint is 21 °C
•
The minimum temperature setpoint of the blue stopper is
+6 °C (21 - 15 = 6)
•
The maximum temperature setpoint of the red stopper is
+30 °C (21 + 9 = 30)
•
If both stoppers are set to their extreme positions, then the
dial can be set between +6 °C and +30 °C
•
If both stoppers are set to the same position, then the dial is
fixed and the temperature setpoint cannot be changed
