Uponor Smatrix Base/Base PRO controls the underfloor
heating/cooling installation according to customer
needs. Temperatures are adjusted with thermostats
located in each room.
10.1 Principle of operation
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 controller. The
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.
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.
For information about operating the interface, see
section 14 Operating Uponor Smatrix Base PRO
interface.
For information about operating the analogue
thermostats, see section 11 Operating Uponor Smatrix
Base/Base PRO analogue thermostat.
For information about operating the digital thermostats,
see section 12 Operating Uponor Smatrix Base/Base
PRO digital thermostat.
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 Thermostat Prog.+RH T-148
• Uponor Smatrix Base Timer I-143
• Uponor Smatrix Base PRO Interface I-147 (Base
PRO only)
For information about operating the thermostat, see
section 12 Operating Uponor Smatrix Base/Base PRO
digital thermostats.
For information about operating the timer, see section
13 Operating Uponor Smatrix Base timer.
For information about operating the interface, see
section 14 Operating Uponor Smatrix Base PRO
interface.
10.4 Run mode
During normal operation the controller is in run mode.
