3 Uponor Smatrix Base PULSE system
description
Uponor Smatrix Base is a management system for underfloor heating
and cooling installations. Comfort, user friendliness and temperature
control for each individual room of a home can be combined through
the various components.
3.1 System overview
Uponor Smatrix Base consists of a room controller, a communication
module (optional), thermostats, and actuators. The room controller
manages the operation of the actuators when the thermostats detect
a demand for heating or cooling.
System optimization and settings (for up to four room controllers) is
facilitated via the Uponor Smatrix PULSE app (connected via the
communication module). The system can function without the
communication module, but with reduced functionality.
Uponor Smatrix Wave is controlled by different types of thermostats.
Designed for maximum comfort, the thermostats communicate with
the room controller by a wired communication protocol. It is possible
to mix the different types of Uponor Smatrix Base thermostats in the
same installation.

Note
The floor sensor can be connected to a thermostat
(except the T-141, T-144, or T-145). Which can be used
for floor temperature limitation.
For example, the maximum limitation can protect a
sensitive floor covering from exposure of too high
temperatures when there is a high heating demand. The
minimum limitation can keep a tiled floor warm even
when there is a no general heating demand for the room.

On/off control
When installing a system with on/off control, manual balancing of the
system is required.
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 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. The indicator on the actuator shows, with a
white bar, how much it is opened. If indicator (white) is fully shown it
is fully opened, no white bar shown means that the actuator is closed.
Time to open and close an actuator may take a couple of minutes.
Uponor Smatrix Base PULSE | Installation and operation manual | 11

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.

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.

Comfort and ECO modes
Note
Use only one Comfort/ECO switch in the system.
•Connecting external Comfort/ECO switch to the
system (public thermostat system device, or GPI),
disables Forced ECO in the Uponor Smatrix PULSE
app.
• Connecting the external Comfort/ECO switch via the
public thermostat system device, disables the
Comfort/ECO option in the GPI.
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.
0 h 00 24 h 0018 h 0012 h 006 h 00
DI0000012
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.
Available cooling methods in the Uponor Smatrix PULSE app.
• Underfloor cooling (UC)
Cooling in the system is achieved using underfloor loops.
• 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.
Electrical underfloor heating
The Uponor Smatrix room controller can operate electrical underfloor
heating (Uponor Comfort-E) using the actuator outputs.
The electrical underfloor heating mat/wire must be connected to the
controller via a relay (dimensioned for the correct load), because of
24V AC controller output.
Heating/cooling offset
Uponor uses an offset temperature to adjust the setpoints when
switching between heating and cooling. This improves the
performance of the system and reduces the need of manual setpoint
adjustments when switching between heating and cooling.
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.
Heating fallback
If the connection to a thermostat is lost, the corresponding loop
cannot be regulated using the room temperature. The room controller
then activates a fallback function for the affected loop and the
actuators are operated with a set interval.
The function is activated until the thermostat is reconnected.
Low hysteresis temperature
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 and cooling, based on information from
sensors and setpoint values.
Uponor Smatrix Base PULSE | Installation and operation manual | 13

Pump management (requires communication
module)
Caution!
Changing status of the pump management and/or
cooling allowed (in the Uponor Smatrix app, requires
communication module) will set all relays to Not
configured. Which will have to be configured again.
Note
In systems with multiple room controllers (master/sub
configuration), all relays are initially set to Not
configured. Which will have to be configured during
installation.
Each room controller has a pump relay, to which one circulation
pump can be connected. Default operating mode of the circulation
pump is set to Individual mode. Use the Uponor Smatrix PULSE app
(requires communication module) to change the setting if needed.
Available settings are Not configured, Common and Individual.
Common mode:
Relay function is set on a system wide basis. One circulation pump
per system is connected (to the master room controller only). When
there is a demand somewhere in the system, the main pump is
started.
Individual mode:
Relay function is set on a room controller basis. One circulation pump
per room controller is connected. When there is a demand to a
specific room controller, only the circulation pump connected to that
room controller is started.
Relative humidity function
Note
RH control is activated in the Uponor Smatrix PULSE
app (requires communication module).
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).
Cooling is shut off on a per room basis when the relative humidity
limit is reached (set in the Uponor Smatrix PULSE app, default 75%).
If a dehumidifier is installed, one per room 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 Uponor Smatrix
PULSE app (“Deadzone”, default 5%).
Room bypass (requires communication
module)
The system can use up to two rooms (per room controller), when in
heating mode, as bypass to maintain minimum flow in the system.
Rooms can be selected manually or by using the Time limit room
bypass function.
Time limit room bypass
The time limit room bypass function prevents shorter run times than
30 minutes in the system. It does this by analyzing system data (if a
room is close to a demand, setpoints, room temperatures etc) and
chooses suitable rooms to use as bypass.
System clock
To facilitate accurate log data, scheduling and different timer settings,
the room controller receives the correct time and date from one of the
input devices (communication module connected to Uponor cloud
services, programmable thermostat etc). The clock can be set to
automatically switch between summer and winter time
(communication module connected to Uponor cloud services only).

See Wiring diagram, Page 92, for more information
Uponor Smatrix Base PULSE system
Note
Setting up a system with a communication module
requires a mobile device (smart phone/tablet).
A connection example of Uponor Smatrix Base PULSE room
rontroller (six channels) with optional Uponor Smatrix Base PULSE
Slave Module (six extra channels and three extra bus connectors),
and Uponor Smatrix Base PULSE Star Module (eight extra bus
connectors), using system devices (S) and thermostats (T) as shown
in figure.
The installation will work in a standard way with the thermostats
regulating each room according to their set temperatures.
16 | Uponor Smatrix Base PULSE | Installation and operation manual

Connections
The system is based on a bus communications protocol (requires the
thermostats unique ID to be registered to the controller), utilising
daisy chain, direct or star topology connections. This allows serial
and parallel connections, making wiring and connection of
thermostats and system devices much easier than connecting one
thermostat per connection terminal.
The wide array of connection possibilities presented with this
communications protocol can be combined in any way best suited for
the current system.
Thermostats and actuators
• Thermostat #01 controls actuator channels 01a, 01b, 02a and
02b with the help of an option.
• Thermostat #03 controls actuator channels 03 to 05 with the
help of an option.
• Thermostat #06 controls actuator channels 06 and 07.
• Thermostat #08 controls actuator channels 08 to 10 with the
help of an option.
• Thermostat #11 controls actuator channels 11 and 12.
System devices
Note
If registering a public thermostat with various functions as
a system device, the thermostat only acts as a remote
unit. It does not control the room temperature in the room
where it is placed.
Note
System devices can only be registered to the master
room controller.
Note
The room controller will time out after about 10 minutes
of inactivity and revert to normal operation. The timer will
be reset when a button is pressed or if a device has been
registered to it.
Note
Sub room controllers can only be registered to the
master room controller.
Note
If a room controller has been connected to a
communication module, disconnect the communication
module and restore it to sub room controller state by
factory reset.
Existing sub room controllers in the system must then
either, reset system device channel 01, or register to
another master room controller.
• Multiple room controllers
Multiple Uponor Smatrix room controllers can be linked together
by assigning one room controller to be master and the rest to be
sub room controllers.
The master room controller is assigned by connecting it to the
communication module (only one room controller can be master
in the system), and it can control up to three sub room
controllers. Sub room controllers are assigned when registered
(in order) to the master room controller.
• Public thermostat T-143 with various functions (options B and
C).
Option A
• External temperature sensor.
• Floor temperature sensor.
Option B
• Outdoor temperature sensor.
Option C
• External temperature sensor for heating/cooling switch.
• Comfort/ECO mode switch.This option disables the
Comfort/ECO option in the GPI.
Schedules
Programmable schedules can, during heating and/or cooling, switch
between Comfort and ECO mode. See example below.
0 h 00 24 h 0018 h 0012 h 006 h 00
DI0000012
Figure 1. Schedule 1
Other rooms can, depending on system setup, simultaneously switch
between Comfort and ECO mode according to their own programmed
schedules.
This requires one or more of the following:
• Uponor Smatrix PULSE app (requires communication module
connected to Uponor cloud services)
The app allows for system wide, or individually programmed,
schedules for the rooms in the system. Any other devices with its
own programmed schedules are overridden and its menus
hidden.
• Uponor Smatrix Wave T-148
The thermostat is in control of its own room, with restrictions
stated above, regarding the Uponor Smatrix PULSE.
0 h 00 24 h 0018 h 0012 h 006 h 00

Heating/cooling switch
The heating/cooling switch is manually controlled through the Uponor
Smatrix PULSE app (which controls the whole system), an external
signal, the supply temperature, or depending on the indoor/outdoor
temperature. It is used to switch the operation of the room controller
between heating and cooling modes.
A single external signal (if used) can be connected to up to four Base
room controllers at the same time, working in parallel. Reducing the
number of heating/cooling switches needed in the system.

5.1 Placement of room controller
Use the following guidelines when positioning the room controller:
• Position the room controller close to the manifold, just above if
possible, and each manifold pair must have its own room
controller. Check the position of the 230 V AC wall socket, or if
required by local regulations, to a junction box, connected to the
mains power.
• Check that the room controller is protected from running or
dripping water.
• Check that the cover of the room controller can be easily
removed.
• Check that connectors and switches are easily accessible.
See Prepare for installation, Page 15, for more information.
Modular placement
B
A
SI0000064
The room controller is designed with the option of modular placement
in mind. This means that all major parts are detachable and can be
placed separately (some extra wiring may be required depending on
placement).
Attaching/detaching components
Caution!
The transformer module is heavy and might detach if the
room controller is held upside down without the cover on.
Caution!
The slave module must be attached by snapping it into
place due to connection pins sticking out of the module.
Note
Wires between transformer and room controller card
needs to be disconnected prior to detaching the
transformer.
