10 Operate Uponor Smatrix Base PULSE
room controller
10.1 Principle of operation
The room controller operates the underfloor heating/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 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 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.
10.2 Normal operation without
optional scheduling -
programs
When the system is running in normal mode:
• In Heating mode, the actuators are open when room
temperatures are lower than the temperatures set on the
thermostats.
• In Cooling mode, the actuators are open when room
temperatures are higher than the temperatures set on the
thermostats.
See Uponor Smatrix PULSE app for more information about
different cooling configurations.
For more information see, Operate Uponor Smatrix Base
thermostats, Page 66.
10.3 Operation with scheduling -
programs
Scheduling programs provide an option to switch selected rooms
between Comfort and ECO mode using a 7-day program. This
optimises the installation and conserves energy.
The use of scheduling programs requires at least one of:
• Uponor Smatrix Base T-148 (programmable thermostat)
• Uponor Smatrix PULSE R-208 (required for mobile app access)
For more information see, Operate Uponor Smatrix Base
thermostats, Page 66
.
For more information see, Operate Uponor Smatrix PULSE
communication module, Page 65.
10.4 Run mode
During normal operation the room controller is in run mode.
Exit to run mode
If the room controller is in registration or forced mode, exit to run
mode by pressing the OK button until the LEDs turn of
f (about 3
seconds).
10.5 Room controller LEDs
If the Uponor Smatrix PULSE app (requires communication module)
is not used, it is recommended to occasionally check the power LED
on the room controller for alarms. The power LED flashes
continuously for general alarms. Determine which thermostats are
