UPONOR CONTROL SYSTEM WIRED - INSTALLATION AND OPERATION MANUAL

3.3.4 Uponor Actuators
Uponor actuators are mounted on top of the valves of the
manifolds
When the thermostat senses that the temperature has fallen
below the setpoint, the controller sends a signal to the actuator
to open the valve. The indicator window on the actuator turns
bright.
When the thermostat senses that the temperature has risen
above the setpoint, the controller sends a signal to the actuator
to close the valve. The indicator window on the actuator turns
dark.
3.4 Function
Uponor Control System Wired is used to control an underfloor
heating system in a house. It can also control a combined heating
and cooling system.
The thermostats that are connected to the controller control the
actuators that are mounted on the manifolds.
For example in a heating system, if a thermostat senses that the
temperature in a room falls below the setpoint, then the
controller regulates the actuators to open more and increase the
heat flow in the floor pipes in the room.
If a thermostat senses that the temperature in a room rises above
the setpoint, then the controller regulates the actuators to close
more and decrease the heat flow in the floor pipes in the room.
3.4.1 Comfort and economy modes
If a timer is connected to the controller, it is possible to regulate
the temperature between two different temperatures, that is
comfort mode and economy mode. See example below.
The diagram shows that the system delivers heating in comfort
mode in the morning and afternoon, but the system enters
economy mode during night and in the middle of the day, when
the house normally is empty.
The controller can use two different timer patterns to regulate
the temperature in different ways in different rooms.
A Actuator has closed the valve – dark indicator
B Actuator has opened the valve – bright indicator
