Chapter 3:
System Description
Smatrix Pulse is a wireless zoning control system designed
for radiant heating and cooling installations with the
ability to integrate forced-air heating and cooling.
System Overview
The Smatrix Pulse hardware consists of one or multiple
controllers, an optional Communication Module,
thermostats, actuators, and wireless relays. The Controller
manages the operation of the actuators when the
thermostats detect a demand for heating and/or cooling.
System optimization and settings (for up to four
controllers) is completed through the Smatrix Pulse App
(connected via the Communication Module). The system
can function without the Communication Module but will
reduce the level of system functionality.
Different models of thermostats control heating and
cooling operation. Designed for maximum comfort, the
thermostats communicate with the controller by radio
link. It is possible to mix the different types of Smatrix Pulse
thermostats in the same installation.
Wireless relays provide installation flexibility when needing
to control other heating and cooling devices when running
additional wiring is a challenge.

Connectivity Features
Actuator Management
Actuator management prevents too many actuators from
being open at the same time. This reduces the peak power
needs. Reduce peak current by delaying the opening of
some actuators (as they use most current while being
opened). Up to eight (8) actuators can be opened at the
same time. Additional actuators are queued and opened
in order.
Autobalancing
The Uponor Smatrix 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 or zones 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 autobalancing continues
through the seasons and throughout the changing
conditions and usage patterns of the household, removing
the need for manual balancing. This gives more even floor
temperatures and faster system reaction times with lower
energy consumption than standard control systems.
Note
Default for Autobalancing is set to On. Setting this
value to Off requires the Communication Module.
Note
Autobalancing can be used in combination with
hydronic balancing.
Smart Home Connectivity
Note
Smart home connectivity requires the use of the
Communication Module (R-208) and the Uponor
Smatrix Pulse App.
Cloud Services
Use the Communication Module to connect to the
Uponor Cloud to access system information and settings,
including:
• Viewing and adjusting room temperatures
• Setting Home or Away status
• Changing mode of operation (heating/cooling)
• Viewing alarms
• Viewing weather forecast
• Viewing room temperature data (trends)
• Setting up Comfort/ECO profiles and assigning to rooms
• Setting low temperature limits (average)
Comfort and Economy (ECO) Modes
Using the Communication Module and Smatrix Pulse
App, it is possible to change the temperature setpoints
between two different temperatures. The available modes
are Comfort and ECO (economy). Use the Smatrix Pulse
App to switch between Comfort and ECO modes and also
create a schedule and apply it to one or multiple zones.

12 l Smatrix Pulse | Installation and Operation Manual
Figure 4-1: Comfort and ECO mode examples
Figure 4-1 shows the system delivers heating in Comfort
mode in the morning and late afternoon but enters
ECO mode at night and in the middle of the day when
the house is normally unoccupied and energy can be
conserved.
Caution!
Connecting an external Comfort/ECO switch to
the GPI terminals on the Controller will override the
time schedules in the Smatrix Pulse App when the
switch is closed. This feature will require setup in
the app.
Note
Use only one Comfort/ECO switch in the system.
Cooling Operation
The controller can operate underfloor cooling installation
based on customer needs. Adjust temperatures with
thermostats or by using the Smatrix Pulse App.
As soon as the temperature measured at a thermostat is
higher than the setpoint temperature, a demand to cool
the room or zone is created and sent to the Controller. The
Controller will open the actuators or turn on the cooling
terminals on the relay according to the current operating
mode and settings. Once the set temperature is reached,
the actuators will close, or the air cooling will turn off.
Cooling Options
Use the Smatrix Pulse App to set up the following two
cooling methods.
• Underfloor cooling (delivered via hydronic loops in the
floor)
• Air cooling (delivered via conventional air conditioning or
fan coil units connected to a relay module registered to a
room thermostat)
Note
If selecting air cooling as the primary method to
cool the room or zone, it is important to turn off the
Autobalancing feature.
Cooling – Second Stage
The Smatrix Pulse system can control a second stage of
cooling. In rooms where underfloor cooling is installed and
a fan coil is also available, underfloor cooling is started
when the room temperature rises above setpoint (first
stage), and the fan-coil cooling is started or activated
depending on how fast the room temperature is
increasing. Second-stage cooling will end once the room
temperature is at or below the set temperature.
The relay must be registered to a thermostat directly for
operation of air-system control. See page 28 for additional
information about registering the thermostat to a relay.
Forced Air/Fan Coils
Use the Relay Module (M-263) (part number A3801263)
to control air heating and cooling. The air heating and
cooling equipment is wired to a relay module and
registered (linked) to a thermostat. The operation is
dependent on the settings in the Smatrix Pulse App.
Caution!
Limit of four (4) Relay Modules for forced air
systems/fan coils per Controller to ensure system
performance.
Caution!
When connecting a Relay Module to control air
heating or cooling, make sure an actuator is not
connected to the first channel the thermostat is
assigned to.
0:00 6:00 24:0018:0012:00

uponor.com l 13
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 for manual setpoint adjustments when switching
between heating and cooling. The offset is 4°F (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 Protection
If the connection to one thermostat or multiple
thermostats is lost (i.e., no longer communicating to a
Controller), the Controller activates a safety feature for
the affected loop(s) and the actuators are run with a
set interval to deliver heating to the room or zone. This
function deactivates when the thermostat(s) reconnect
or unregister from the Controller.
Pump Management
Each controller includes a pump relay to connect
a circulation pump. Default operating mode of the
circulation pump is set to Individual mode. Use the
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 Primary Controller only or Controller that is connected
to the Communication Module. When there is a demand
anywhere in the system, the pump wired to the Primary
Controller is started.
• Individual mode: Relay function is set on a Controller
basis. One circulation pump per Controller is connected.
When there is a demand to a specific Controller, only the
pump connected to that controller is started.
• Relay module (optional): When using the relay module
to control a pump, the mode of the pump control is set
through in the Smatrix Pulse App.
Caution!
Changing operation of the pump control (and/or
cooling allowed) in the Smatrix Pulse App will set
all relays to Not Configured, and they will need to
be reconfigured.
Note
In systems with multiple Controllers (Primary/
sub-configuration), all relays are initially set to
Not Configured and require configuration during
the installation.
Relative Humidity/Condensation Control
To avoid condensation when operating underfloor cooling,
Uponor recommends measuring the relative humidity (RH)
in the rooms. The relative humidity is measured with one
or more thermostats.
Cooling is shut off on a per-room or zone basis when the
RH limit is reached (set in the Smatrix Pulse App, default
75%). If a dehumidifier is installed, one per 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 Smatrix Pulse App (“dead zone”,
default 5%) and has run for a minimum of 30 minutes.
Room Bypass
The system can use up to two rooms (per controller), when
in heating mode, as bypass to maintain minimum flow in
the system. Rooms can be selected manually or by using
the Room Bypass Time Limit function.
Room Bypass Time Limit
The Room Bypass Time Limit function prevents run times
shorter 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 Controller receives the correct time and
date from Uponor Cloud services. The clock can be set to
automatically switch between summer and winter time.

Installation Procedure
Uponor recommends the following steps to provide the
best possible installation results:
• Prepare for Installation (see page 15)
• Install Controller(s) (see page 16)
• Install Communication Module or Antenna
(see pages 17-18)
• Install the Relay Module (see page 18)
• Install Thermostats (see page 19)
After installing the hardware, Chapter 6: Wiring will
describe how to wire the system components, connect
the wireless devices, and finalize setup using the Smatrix
Pulse App.
Prepare for Installation
• Verify the contents of the package with the packing list.
• Check whether an external temperature sensor (e.g., floor
sensor) is to be installed with a thermostat.
• Review the wiring diagram in the manual or inside the
Controller cover.
• Ensure the Controller can be installed near the manifold.
Note that each manifold should have its own controller
(unless the manifold is a single zone).
• Ensure all Smatrix Pulse components are protected from
exposure to water.
Required Tools
Refer to the following list of tools required to install the
Smatrix Pulse hardware:
• Wire cutters
• Small Phillips screwdriver
• Flathead screwdriver
• T-10 bit (wiring compartment on the controller)
• Level
Installation Example
Figure 5-1: Installation example

16 l Smatrix Pulse | Installation and Operation Manual
Installation Overview
• The example system has five (5) heating zones and one
(1) cooling zone (Main Floor).
• The Main Floor is registered to Channel 1 but has no
actuator(s). This is due to the system controlling forced-
air heating and cooling but no radiant. In instances like
this, the thermostat needs to be assigned to a channel
(in this case, 1) and registered to the relay.
• Bedrooms thermostat is assigned to Channels 2 and 3
and will control actuators connected to 2A, 2B, and 3.
• Family Room heating will open actuators connected to 4
through 6.
• Master Bath heating will open actuators connected to 7.
• Garage thermostat is assigned to Channel 8, but no
actuator is connected. The Garage thermostat is also
linked to a relay module to operate a zone pump on a
call for heating.
Caution!
All thermostats need to be registered to a
controller for it to appear in the app
Hardware Handling
• The Primary Controller is the device that is connected to
the Communication Module. All others are sub-Controllers.
• A system does not require a Primary Controller, however,
system functionality will be limited.
• Sub-Controllers can only be registered to the Primary
Controller.
• Relay modules can be registered to both Primary and
sub-Controllers.
• The Digital Thermostat (T-169) (part number A3800169) is
the only thermostat that can connect to a Relay Module.
• A thermostat can only be linked to one Controller.
• The Controller will time out after 10 minutes of inactivity
and revert to normal operation. The timer is reset when a
button has been pressed.
• If programmed schedules exist, individual rooms may
operate without following a schedule.
• Setting up a system for remote access and connectivity
will require a mobile device (e.g., smartphone, tablet,
etc.).
A380265C/A380265A Controllers
Controllers are designed for modular installation, meaning
the individual parts (Transformer, Controller, Expansion
Module, and end cap) easily snap together. However,
should the installation require it, the power supply, or
Transformer (part number A3850050), can be mounted
separately.
Caution!
The Transformer is heavy and might detach if the
Controller is held in a vertical position (or upside
down) without the cover on.
Caution!
The Expansion Module must be attached by
snapping it into place due to connection pins used
for connecting to the Controller.
Note
Wires between the Transformer and the Controller
must be disconnected prior to detaching the
Transformer.
The components can snap on or off without needing to
remove the covers or by sliding them into place when the
covers are removed.
Note
Only one Expansion Module is supported per
controller.
Mounting the Controller
• Find a suitable location in proximity to the manifold and
115V power supply/outlet.
• Remove the DIN rail from the package and place on the
wall and level. Note that the DIN rail included will support
both the Controller and the Transformer.
• Mark a minimum of two locations per DIN rail for screw or
anchor locations.
• Install the DIN rail onto the wall surface using the
necessary hardware.
• Assemble or connect all components prior to installing
on to the DIN rail.
• Snap the assembled hardware onto the DIN rail.

Communication Module (R-208)
The Communication Module contains both an antenna for
internal connections to thermostats and sub-controller
and a local network (LAN) module for Wi-Fi or Ethernet
communication.
Mounting the Communication Module
Caution!
Do not install a Communication Module inside a
manifold cabinet.
Caution!
Install the Communication Module vertically to
ensure the best communication.
• Remove from the packaging and separate the
Communication Module from its removable back mount.
• Attach the back mount to the wall using the hardware
included in the packaging.
• The back can be attached to the wall using adhesive
tape, screws, wall anchors, or DIN rail.

Antenna (A-265)
The Antenna is packaged with
a Controller in part number
A380265A. The Smatrix Pulse
system can be installed
with antennas only and no
Communication Module, so be
aware that system functionality
will be limited (see Chapter 4:
System Functionality). When
installing a system solely with
antennas, each Controller will
operate independently. When
installing and linking a Controller
in a system with a Controller that
is connected to a Communication
Module (primary), additional
Controllers with Antennas become
sub-Controllers.
Caution!
Install the Antenna outside a manifold cabinet.
Caution!
Install the Antenna vertically to ensure the best
communication.
Mounting the Antenna
• Attach the Antenna to the wall using the adhesive strips
included in the packaging.
Connecting the Antenna
• Route the Ethernet cable attached to the Antenna and
plug it into the connection on the bottom right hand of
the Controller.
• A click should be audible with a completed connection.
• Apply gentle pressure pulling down on the Ethernet cable
to ensure the connection is secure.
A3801263 Relay
Module (M-263)
Using a Relay Module
helps integrate other
systems (forced air/
fan coils, etc.), simplifies
or reduces wiring
complexity, and provides
a solution where it is
difficult to run wires to
activate heating (and
cooling) equipment.
Different functionality combinations are available when
using the Relay Module. To access these requires the
Communication Module.
Placing the Relay Module
Use the following recommendations when determining the
location of the Relay Module:
• Locate the Relay Module close to the device it will control.
• Place the Relay Module above the device(s) to avoid
potential water damage.
• Ensure the Relay Module is protected from exposure to
water.
• Check to make sure the cover can be easily removed
(there is proper clearance) and the terminals are easily
accessible.
Mounting the Relay Module
• Attach the Relay Module to the wall or surface.
• Use suitable hardware included in the packaging to
secure the Relay Module to the determined locations.
