The controller HMI Compact or HMI Toutch Panel 4,3`` or 7``
can be connected to the HMI CON port (located in the top
panel of the controller near the USB port) or to the RS485
Master port - if it is not used to transmit information with
the BMS management system. It is possible to connect two
controllers simultaneously, one of them to the HMI CON
port and the other to the RS485 Master port - in this case we
cannot connect the controller from the BMS of the object.
The controller HMI Compact is equipped with a “simple/
ext” jumper, its opening causes the controller to work with
a partially hidden menu, this function will not allow the op-
erator to enter the “service menu”, where we congure the
ventilation system.
The controller menu is always visible in its entirety.
Touch-screen controllers HMI Toutch Panel 4,3` or 7`` HMI
are operated by a controller equipped with an additional
memory card, such a controller is marked with an addition-
al “+” symbol on its label.
The USB connector is used to upload the controller applica-
tion, if the application of the controller does not meet the
requirements of the customer contact the manufacturer
or supplier, it is possible to adapt the application to the
requirements and upload it using any PC class computer.
