Installation and Operation Manual

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.
Comfort and ECO modes
Note
• Connecting external Comfort/ECO switch to the
system (public thermostat system device, or GPI),
disables Forced ECO in the Uponor Smatrix PULSE
app.
•
Using the communication module and Uponor Smatrix PULSE app,
or an external switch (connected to the GPI or public thermostat), it is
possible to regulate the temperature setpoint modes between two
different temperatures. Available modes are Comfort and ECO
(economy).
Switching between the Comfort/ECO modes can automatically be
scheduled by connecting the communication module to Uponor cloud
services. Scheduling in systems without a communication module
requires a programmable thermostat, but it can only schedule
Comfort/ECO in the room where it is registered.

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
.
Cooling function
The room controller operates the underfloor cooling installation
according to customer needs. Temperatures can be adjusted with
thermostats located in each room, or if installed with the Uponor
Smatrix PULSE app (requires communication module).
As soon as the temperature measured at a thermostat is higher than
the setpoint temperature, a demand to change the room temperature
is created and sent to the room controller
. The room controller will
open the actuators according to current operating mode and other
settings. Once the set temperature is reached, this information is sent
and the actuators are closed.
Uponor Smatrix PULSE app (requires
communication module)
The system supports different types of cooling methods and is setup
in the Uponor Smatrix PULSE
app.
A
vailable cooling methods in the
Uponor Smatrix PULSE
app.
• Underfloor cooling (UC)
Cooling in the system is achieved using underfloor loops.
• Fancoil (FC)
Cooling in the system is achieved using fancoils (connected to a
relay module registered to a room thermostat).
Note! Autobalancing (Installer settings) should be disabled in the
system.
In rooms where underfloor cooling is allowed and a fancoil is
installed, underfloor cooling is started when the room
temperature is a couple of degrees above setpoint (1st stage),
and the fancoil is started at setpoint (2nd stage cooling).
•
Ceiling cooling (CC)
Cooling in the system is achieved using ceiling cooling (2-pipe or
4-pipe system).
Select if the system utilizes a 2-pipe or 4-pipe delivery solution
for heating/cooling.
-
2-pipe means one supply temperature to the system at a
time (heating or cooling).
Autoblancing disabled:In rooms where underfloor heating/
cooling is allowed. Underfloor cooling and ceiling cooling is
both started when the room termperature is about 1
degree above setpoint.
Autobalancing enabled: Ceiling cooling and underfloor
cooling will follow the current cooling demand.
-
4-pipe means separate independent heating/cooling
sources.
In heating mode:
The underfloor loops are used when there is a heating
demand. Ceiling cooling is used when there is a cooling
demand.
In cooling mode:
Underfloor loops and ceiling cooling are used at the same
time when there is a cooling demand.
See Uponor Smatrix PULSE app for more information about the
individual functions.
