1 Installation
1.1 General
Caution!
Send all settings from BMS, such as set points, limits,
override etc. cyclically. Max 30 minutes interval time is
recommended.
Note
Basic knowledge and training on BMS and Modbus RTU
is required for installation and setup of Base PRO with
Modbus RTU.
Note
General setup handling, such as thermostat registration,
can be found in the Quick Guide for Uponor Smatrix
Base PRO (X-147).
The Uponor Smatrix Base PRO Controller X-148 Modbus RTU is
preloaded with the correct software for connection and integration to
a building management system (BMS) through a Modbus RTU
connection over RS-485.
The BMS gets access to the following in the Base PRO system.
Read:
•
Outdoor temperature
•
Room temperature
•
Floor temperature
•
Humidity level
•
Actuator status
•
Pump or boiler status
•
General purpose input (GPI) status
•
Loss of thermostat connection
•
Dynamic heat curve offset in integrated heat pump*
Read and write:
•
Room setpoint
•
Min/max levels for setpoint
•
Activation of setpoint overrride for analog thermostats
•
Min/max levels for floor temperature
•
Heating/Cooling state
•
Heating/Cooling offset
•
Comfort/ECO
•
Autobalancing on/off
•
Cooling not allowed for a room
•
Comfort setting
•
Integrated heat pump defrost state*
•
Relative humidity (RH) control
* Requires Heat Pump Integration via BMS to be activated in U_BMS.txt.
1.2 Preparation
To connect a BMS to the Uponor Smatrix Base PRO controller some
preparations must be made.
1.

Software
The controller X-148 Modbus RTU is preloaded with the correct
software already when delivered.
Uponor Smatrix Base PRO Controller X-148 Modbus RTU
Caution!
If an Uponor Smatrix Base PRO Interface I-147 is
connected, it must be unregistered and disconnected.
Caution!
Do not remove the microSD card while the controller is
powered on.
Caution!
Be careful when editing the configuration in the
U_BMS.txt file.
Preferably use Notepad in Windows since other editors
might add scrap and/or hidden characters to the file.
Note
Make sure that the thermostats are registered to
consecutive channels so the BMS can read and write all
channels in an efficient way. That is, addressing multiple
channels in one message.
Note
Make sure the correct slave address is set (between 1
and 247, unique for each controller in the system), and
that the other communication settings in the U_BMS.txt
file match the Modbus RTU settings in the BMS.
