4.5 External supervision
The IQnomic Plus module is used for external supervision
by means of analogue and digital signals (function selector
switch set to position 3, see figure) when regular means
of communication with the air handling unit cannot be
used. The module is, for example, suitable for use if the air
handling unit is to be controlled/supervised via a computer
substation or a PLC system.
The function can be activated in the terminal of the unit or
via a communication interface.
Relay 1 Connects between Terminals 1 and 2
when the control unit, in the terminal,
indicates Selected function*, active
Factory-preset function: Heating by
means of heat exchanger required.
Relay 2 Connects between Terminals 4 and 5
when the control unit, in the terminal,
indicates Selected function*, active.
Factory-preset function:
