3.5 Functions
Uponor Smatrix Base/Base PRO is used to control an
underfloor heating and/or cooling system in a house or
building.
The thermostats registered to the controller is used to
control the actuators mounted on top of the manifold
valves.
As soon as the temperature measured at a thermostat
is lower (heating mode) or higher (cooling mode) than
the setpoint temperature, a demand to change the
room temperature is created and sent to the controller.
The controller will operate the actuators according to
current control mode and settings. This will manage the
flow to the floor loops in the room and adjust the room
temperature. Once the set temperature is reached, this
information is sent to the controller and the demand is
met.
If a timer is connected to the controller, it is possible to
regulate the temperature setpoint modes between three
different temperatures. Available modes is Comfort,
ECO (economy), and Holiday. See example of Comfort
and ECO mode below.

The diagram shows that the system delivers heating in
comfort mode in the morning and afternoon, but the
system enters ECO mode during night and in the middle
of the day, when the house normally is empty.
