Running mode
In this menu the running mode for the system can be
checked and also set to manual control.
To the left the display shows Auto/Manual and to the right
the present running mode.
The modes AUTO/ON/OFF can be set.
In AUTO the running mode is set by the scheduler
program or by signals on DI7/DI8.
If the controller is configured for two-speed fans the
modes AUTO/LOW/HIGH/OFF can be set.
The menu is available from level 1 and up.
AI Analogue inputs
Displays current values for AI1...AI8.
The displayed sensor temperature can be adjusted
by ±2K. Available for level 3.
Maximum and minimum temperatures since last reset can
be shown. Activated in menu ”Settings”.
DI Digital inputs
Displays current values for inputs DI1...DI8.
AO Analogue outputs
Shows current values for AO1...AO3.
The outputs can be manually set. From level 1 and up.
If an output is not reset to AOTO within 15 seconds an
alarm is activated.
DO Digital outputs
Shows current values for DO1...DO7.
The outputs can be manually set. From level 1 and up.
If an output is not reset to AUTO within 15 seconds an
alarm is activated.
Scheduler
The Corrigo has a year-base clock. This means that a
week-schedule, individual holidays and holiday periods
for a full year can be set.
The clock has at least 24 hours running reserve.
1. Clock
Here weekday, date and time are set. Level 1 and up.
2. Scheduler period 1, 2, 3.
Setting of running periods. Level 2 and up.
Corrigo has 3 scheduler periods so that separate
running times can be set for, for example, weekdays,
Saturdays and Sundays/holidays. In each period, mark
the days and time interval in which the system should
be in normal running mode. Use the arrow keys to
select/deselect days in the period. End each selection
with
OK
.
The day H is used if the system is to have running time
during holidays or holiday periods.
3. Reduced 1, 2, 3.
3 periods for running with reduced airflow.
Should not overlap periods set for normal running.
Should periods overlap Corrigo will choose normal
running before reduced.
4. Dates for holidays. Level 2 and up.
A total of 10 individual holidays can be set. Running
time during a holiday is set by programming the day
H into one of the three scheduler periods. If none of
the periods contains the day H the system will be shut
down on holidays.
5. Holiday periods. Level 2 and up.
2 periods comprising any number of days may be
programmed. Running time during a holiday is set by
programming the day H into one of the three
scheduler periods. If none of the periods contains the
day H the system will be shut down on holidays.
Alarm settings
Here all settings for the alarm system are set.
1. Sensor alarm
Should the actual temperature differ from the setpoint
by more than the set value an alarm will be activated
after a set time.
2 Outdoor temperature range within which sensor alarm
is permitted.
To prevent alarms when the outdoor temperature
leads to conditions beyond the system capacity. (For
example at temperatures higher than the setpoint in
systems without cooling).
3 Alarm delay for the supply air fan.
Startup alarm supression time.
4 Alarm delay for the exhaust air fan.
Startup alarm supression time.
5 Blocking of the alarm output relay.
The alarm output relay can be blocked so that alarms
only will be forwarded during the set time. Outside the
set period only frost alarm, high temperature limit
alarm and fire alarm will activate the alarm relay.
Other alarms will be blocked. All alarms will however,
at all times be registered in the internal alarm list and
indicated by the red flashing alarm diod. The alarm
list menues function as normal.

LED’s
The LEDs are connected to the functions of certain in-
and outputs. Normal running indication is yellow. A red
LED signifies an error. The text strip can easily be
changed to reflect various configurations

6. Stop unit on alarm from rotating exchanger
A rotating heat exchanger alarm on input DI4 will stop
the whole unit.
This in order to prevent uneconomic running and
running att too low a temperature.
Is only displayed if rotating exchanger has been
configured.
