CORRIGO C40-LON INSTRUCTION
Corrigo C40-LON is a controller primarily intended
for controlling air handling units. It can easily be
adapted to suit different types of units.
Corrigo C40-LON has built-in capability for LON
communication. See separate LON interface manual.
Corrigo C40-LON has six 0...10 V DC control outputs,
three in sequence for controlling for example heating /
heat exchanger / cooling and two for speed control of
supply air fan and exhaust air fan and one for humidity
control. It has a number of functions and possibilities,
such as DX-cooling in one or two steps, outdoor
temperature compensation, fire damper exercise, control
and monitoring of fans and circulation pump, free
cooling, heat-exhanger efficiency calculation etc.
Corrigo C40-LON can also receive and handle a number
of alarms such as fan and filter alarm, smoke alarm,
chiller alarm, heat-exchanger alarm and has a free relay
output for total alarm. Corrigo C40-LON has a year-base
real-time clock, week-scheduler , holiday calendar,
holiday periods and automatic normal time/daylight
saving time change-over.
Installation
Mount the unit on a DIN rail in a cabinet or separate
enclosure.
For mounting in the cabinet front, use mounting kit FMC.
Degree of protection IP20
Ambient temperature 0...50°C
Wiring
Supply voltage
Terminals 42 and 43: 24 V AC, ±15%, 50/60 Hz.
Fan speed control, supply/exhaust air fans AI1, AI2
Connect AI1 and AI2 to pressure transmitters measuring
the pressure over each fan. Use transmitters with a
0...10V DC output signal. The pressure range is
adjustable.
N.B. Since these signals control vital functions they must
be connected for the unit to work as intended.
Analogue inputs AI1...AI8
N.B. All AI-inputs must refer to the signal neutral terminals
for AI-inputs (terminals 24, 27, 30, 33).
Humidity sensors AI3, AI4
AI3 and AI4 are to be connected to humidity transmitters
with output 0...10 V DC corresponding to 0...100% RH.
AI3, room humidity sensor, main sensor.
AI4, duct humidity sensor, limiting sensor placed in the
incoming air duct after the air handling unit.
Sensors AI3...AI8
Use PT1000 sensors. (See data sheet 4-150).
The choice of which sensors to connect is determined by
the choice of functions. The table, fig 3 can be used as an
aid in determining which sensors to install.
Connect the sensors according to the terminal schematics
on page 6.
AI8 is, depending on setting, used for:
1. Frost protection sensor for applications with water
heated heater.
2. High temperature limiting switch for applications with
electrical heater.
When used for high temperature limiting switch it must be
connected to a free contact closing on alarm.

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.

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.
2Outdoor temperature range within which sensor alarm
is permitted.

leads to conditions beyond the system capacity. (For
example at temperatures higher than the setpoint in
systems without cooling).
3Alarm delay for the supply air fan.
Startup alarm supression time.
4Alarm delay for the exhaust air fan.

2. Fire damper exercising
Wire all the damper end-position switches to DI6
according to the figure above. The contacts must close
when the actuator is at either end position.
At a preset time DO6 will activate all the dampers. DI6
must then be deactivated within 3 minutes, indicating
thet the dampers have left their normal end position , or
an alarm will be activated. When DI6 has been
deactivated it must be activated again within 3 minutes
indicating that the dampers have reached the other end
point. When DI6 is activated the output DO6 is
deactivated and the dampers begin to return to the start
position. To avoid an alarm output DI6 must once again
be deactivated within 3 minutes and then activated
again within 3 minutes indicating that the dampers are
back in their original position.
