Uponor Smatrix Base PULSE User Manual

PWM control
Note
Autobalancing can be used in combination with hydronic
balancing.
PWM control is used when the Autobalancing function is active.
When installing a system with PWM control, all balancing valves can
be fully opened, the system is balanced automatically.
See Autobalancing, Page 12, for more information.

3.5 Functions
Note
Setting up a system with a communication module
requires a mobile device (smart phone/tablet).
The Uponor Smatrix room controler is used to operate an underfloor
heating and/or cooling system in a house.
The room controller can also control heating via electrical underfloor
heating using an external relay.
The thermostats registered to the room 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 room controller. The room 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 room controller and the demand is met.
Actuator management
Actuator management prevents too many actuators to be open at the
same time in order to reduce the peak power need. Peak current can
be reduced by delaying the opening of some actuators, as they use
most current while being opened.
Up to eight actuators in up to six rooms can be opened at the same
time. Additional actuators are queued and opened in order.
Autobalancing
Note
Autobalancing can be used in combination with hydronic
balancing.
The Uponor Smatrix room controller can operate the actuator outputs
by either on/off signals or by Autobalancing (on by default), using
pulse width modulation (PWM) signals.
Autobalancing is a function where the system calculates the actual
energy need of single rooms and adapts the output power of each
loop to its length. This means a short loop might get 20% on time
while a long loop might get about 60%.
The automatic balancing continues through the seasons and
throughout the household’s changing lifestyle and usage patterns,
removing the need of manual balancing.
This gives more even floor temperatures and faster system reaction
times with lower energy consumption than any standard on/off
system.
