Serial connection of several iVent 8A ventilation control panels
Options without using the Service Port Software
Sensor technology
Here different sensors (e.g. temperature sensor) can be interconnected externally; it should however be noted that one
circuit for opening the windows and one circuit for closing the windows must be connected externally.
Example:
At the sensor terminal points there is a supply voltage for the sensors for both the open and the closed directions,
Terminal 15 and 19 (+27 V) Terminals 16 and 20 (GND).
In order to open, Terminals 13 and 14 of the iVent 8A
1
must be bridged.
In order to close, Terminals 17 and 18 of the iVent 8A
1
must be bridged.
Vent switch
The closer contact "OPEN" is connected to Terminal 09 and 12 of the iVent 8A
1
. The closer contact "CLOSED" is
connected to Terminal 10 and 12 of the iVent 8A
1
. An optional indicator (LED) can be connected between Terminal 03
(+27 V) and Terminal 04 (GND) of the iVent 8A
1
. This indicator is illuminated as soon as the iVent 8A
1
transmits the
"window open" signal.
Wind and rain detector WRM
The WRM is supplied with voltage via Terminals 23 (+27 V) and 24 (GND); the WRM switching contact is connected to
Terminals 21 and 22.
Drive 1
Drive 1 is connected to Terminals A1 and A2 of the iVent 8A
1
; there are two of these terminals for each
iVent 8A, so that two drives can be connected.
Drive 2
The drive
2
is connected to the Terminals A1 and A2 of the iVent 8A
2
.
