2) Modbus slave
Using BMS (Building Management System), several devices can be controlled simultaneously or one device
can be controlled using several controllers. MODBUS protocol allows changing all parameters of controllers and
monitoring data of connected sensors.
3) Fan control when speed is set using controller and/or
computer via Modbus
Using this remote controller and CO2 transmitter it is possible to reduce inside carbon dioxide level. This con-
troller allows controlling both device and 0..10VDC fan. In service menu, select desired speed control method
(F.01). If control based on preset speeds is selected, then select them in menu items F.03, F.04, F.05, F.06.
NOTE: The air quality converters and remote controller (when fan is controlled) must be powered from a
separate power source. It is not supplied with the remote.
4) Pressure control when selected using controller and/or
computer via Modbus
Desired pressure can be maintained by connecting 0..10VDC fan and 0..10VDC pressure converter directly to
the controller. Control and pressure sensor parameters can be changed in controller. When controller is used as
Modbus slave device (air handling unit is not controlled by this principle), it allows controlling all parameters and
monitoring of pressure sensor readings.
For pressure based control, select the following parameters in the service menu:
• .4 - 1
• .5 and .6 -based on pressure converter parameters
• ., . and .3 - (PID control ratios). If pressure is maintained incorrectly, these parameters can be
adjusted.
