Analogue 0...10 V DC control outputs, AO1...AO6
Output signal 0...10 V DC, 5 mA. Short circuit proof.
AO1
Control output Y1
AO2
Control output Y2
AO3
Control output Y3
The function of the different outputs depends on the
configuration settings but the sequence order will always
be Y3

Y1 on increasing heat demand.
AO4
Control output, supply air fan
AO5
Control output, exhaust air fan
AO6
Humidity control
These outputs must refer to terminal 41, Signal neutral.
Since signal neutral in the Corrigo is electrically
separated from system neutral the signal neutral from
the actuator must be connected to terminal 41 even if
the actuator and the Corrigo share a common trans-
former.
Other control outputs, DO1...DO7
The digital outputs DO1...DO6 are triac controlled.
0,5A, 24 V AC. Short term peak load 1A.
Output DO7 is a potential free relay contact.
The outputs are paired to 24 V AC supply inputs. (See
terminal schematics, page 6).
For higher voltages and currents use relay modules
RM6-24/D or RM6H-24/D that are specially designed for
use with Corrigo.
Some of the outputs have alternative functions
depending on the system configuration.
DO1
Activate supply air fan.
DO2
Activate exhaust air fan.
DO3
Control circulation pump.
DO4
Control DX-chiller 1
DO5
Control DX-chiller 2
DO6
External frost protection or fire damper exercising.
(See text section DO6/DI6 page 6).
DO7
Potential free relay contact for alarm output.
1 A, 24 V AC/DC. Closes on alarm.
Buttons and display
Language
The menu text language can be changed.
Hold the
!
button depressed during power up to enter the
setup mode. Then press
!
again and a blinking marker
will appear next to the current language. Select the desired
language by using the arrow buttons. When the marker is
next to the desired language, press
OK
. Press
OK
again
to return to the normal menu system.
All information that can be shown on the display is organi-
sed in menues in a ”menu-tree”.
Using the buttons on the front you can move between the
different menues in the tree, look at parameters, change
settings, display and reset alarms.
What you can see and do is governed by your log-on level.
The ”Trunk” of the menu-tree contains the following
menues:

During normal running when the buttons are not in use a
series of menu pages is shown.
The display alternates between, a general display with
product description and clock, setpoint/actual temperature,
and output status for the control outputs Y1, Y2, Y3.
To gain access to the menu-tree press
OK
and the display
will change to
Control temp
.
By pressing
é
and
ê
you can move up and down the tree.
The arrows to the right in the display indicate whether
there are menu pages above or below the one shown.

To move out onto any of the ”branches” press
OK
. Out on
the branch you can then move about in the same way
using the arrowbuttons. By pressing
Esc
you can jump
back towards the trunk.
In menu pages with settable parameters you shift to
”Setting mode” by pressing
!
.
A dark blinking marker will then appear in the first settable
position. By using the arrow buttons the value can be
changed. When the correct value is shown press
OK
and
the marker will move to the next position. After
OK
on the
last position the new value is stored and the ”Setting
mode” is ended.
To abort without change press
Esc
and the marker will
move back to the previous position. Setting mode is
aborted automatically after a few minutes button-inactivity.
Shows the alarm queue. Displays active and non-
acknowleged alarms. The alarm-LED above the button is
lit when there are alarms in the queue.If there are multiple
alarms use the arrow buttons to move between pages.
Alarms are acknowleged by pressing
OK
.
To abort press
Esc.
Login
Corrigo has 4 different login levels to prevent the user
from inadvertently changing any settings.
0
Without logging in most of the important parameters
can be viewed, alarms can be acknowleged but no
parameters can be changed.
1
Main setpoint, time and date can be set.
Outputs can be manually set and the running mode
can be set to manually on or off.
2
Gives access to most setpoints and running para-
meters.
3
Gives total access.
Used by the commissioning engineer for system
configuration.
Enables changing of login codes.
To login when the display shows the normal series of
information menues, first press
OK
and the display will
show

DI7 and DI8 should, depending on settings, either be
wired to a momentarily closing pushbutton or to, for
example, a timer.
If DI7 and DI8 are both closed at the same time the unit
is shut down.
If a separate handswitch for setting the running mode is
installed it should be wired according to figure 1.
