Autobalancing can be used in combination
with hydronic balancing.
DE
The Uponor Smatrix Base/Base PRO controller can
operate the actuator outputs by either on/off signals
or by Autobalancing (on by default), using pulse width
DK
modulation (PWM) signals.
Autobalancing is a function where the system calculates
the actual energy need of single rooms and adapts the
EE
output power of each loop to its length. This means a
short loop short might get 20% on time while a long
loop might get about 60% on time.
ES
The automatic balancing continues through the seasons
and throughout the household's changing lifestyle and
FI usage patterns, removing the need of manual balancing.
This gives more even floor temperatures and faster
system reaction times with lower energy consumption
FR
than any standard on/off system.

oW hysteresis temPerature
HR
Uponor uses a low hysteresis temperature for best
performance of the system. It is used for high control
accuracy by deciding when to start and stop heating
HU
and cooling, based on information from sensors and
setpoint values.

h /
eating Cooling offset
Uponor uses an offset temperature to adjust the
setpoints when switching between heating and cooling.
LT
This improves the performance of the system and
reduces the need of manual setpoint adjustments when
switching between heating and cooling.
LV
The offset is 2 °C and is used to increase the setpoints
when switching to cooling. When switching back to
heating, the value is used to reduce the setpoint. The
NL
offset can be changed using an interface I-147 (Base
PRO only).

elative humidity funCtion
To avoid condensation when having a cooling system, it
is recommended measuring the relative humidity (RH)
in the rooms. The relative humidity is measured with
one or more thermostats (with RH sensor).
Uponor Smatrix Base
Cooling is shut off for the whole system if the RH
reaches a "worst case level" of 80% in one of the
thermostats (if more than one).
Cooling will start again when the relative humidity falls
below 76%.
Uponor Smatrix Base PRO
Cooling is shut off on a per room basis when the relative
humidity limit is reached (set in the interface, default
75%). If a dehumidifier is installed (requires an Uponor
Smatrix Move PRO controller) it will be activated when
the dehumidifier start limit is reached.
Cooling will start again and the dehumidifier is
deactivated when the relative humidity falls below a
hysteresis set in the interface ("Deadzone", default
5%).
P
umP management
The controller in a system has a pump relay, to which
one pump can be connected. If there is some sort
of demand in a room, the pump is started. In a Base
PRO system, with an interface connected), the pump
management parameter is automatically set to common
mode. Use the interface to change the setting if
needed. Available settings are Common, Individual
and H/C switch.
Common mode (Base PRO with interface only):
Relay status is set on a system wide basis. One pump
per system is connected (to the master controller only).
If there is a demand in one room of the controllers, the
main pump is started.
Individual mode (Base PRO with interface only):
Relay status is set on a controller basis. One pump per
controller is connected. If there a demand in a room,
only the pump connected to that controller is started.
