Introduction
COORIGO is a completely new range of controllers which has been designed to be
easy to use and operate. The controllers have a display and built in panels for
operation and alarm on the front and are operated by means of clearly defined
buttons.
The controllers have been designed for mounting on a DIN rail, in norm housing or
on the front of a cabinet.
The required functions are selected with the help of questions in normal script or by
means of a code under the configuration menu depending on the type of
application.
The controller has a year-base clock and automatic summer/winter time
changeover.
The menu system works with different user-levels to show settings and to allow
settings to be altered. This means that non-technical staff can feel secure while
using the system since it is impossible, on the lower user-levels, to programme
incorrect settings when checking operating status, parameter values, alarms etc.
During normal operation, without pressing any buttons, the display also shows the
most important operating statuses such as setpoint/current value, sequence-output
control and time/date/version etc.
We hope you will be satisfied with your CORRIGO and that it will provide you with
simpler and more economic running of your control systems.

Installation
CORRIGO can be mounted in standard casing, on a DIN rail in a cabinet or in the
front of a cabinet.
Front mounting kit
When CORRIGO is to be placed in a cabinet front mounting will be facilitated using
the front mounting kit FMK1. The kit contains a front frame with see-through lid and
an integrated mounting-rail.
When placing two CORRIGOs or one CORRIGO and one relay unit RM6..-24/D next to
each other in the front of the cabinet use the FMCR mounting kit. It contains the
same parts as FMC above but they are of different dimensions.
Supply voltage
The controller is to be supplied with 24VAC. Terminal 43, system neutral, is
internally connected to terminal 41, signal neutral for the analogue outputs, and
terminals 24, 27, 30 och 33, signal neutral for the analogue inputs.
Inputs
The controller has common poles for signal neutral to transmitters (AI 1-8) and a
common pole for digital input signals.
Terminal 22 (common for digital input signals) is not the same as signal neutral for
transmitters ( terminals 24,27,30 and 33) and they must not be interconnected.
Signal neutral terminals for transmitters (24,27,30 and 33) are, however, internally
connected and connected to system neutral on terminal 43.
Outputs
The analogue outputs give 0...10 V DC. Signal neutral on terminal 41 is internally
connected to system neutral on terminal 43.
Digital outputs are supplied in pairs with 24V AC on the terminals which are marked
with 24V AC in (terminals 6,9 and 12). Each output has an internal triac which gives
24VAC. Terminals 6, 9 and 12 are also internally connected.
Service pin
On the LON-models the comissioning service pin is located behind a marked
opening on the upper side of the CORRIGO.

Manual CORRIGO C-SERIES 2000.09
AI Analogue in
CORRIGO has 8 analogue inputs, AI1...AI8
The function of some of the inputs varies depending on the choice of model and
configuration.
PT1000 type temperature sensors must be used on those inputs that are
configured as temperature inputs.
In certain cases an AI-input may be used as a digital input. It must then be
connected to a voltage-free, closing contact.
When active input signals are connected they must be 0...10 V DC.
AI-inputs must always use the signal neutral of the AI terminal block as reference.
(terminals 24, 27, 30 or 33).
AI1 and AI2
are used for connecting pressure switches/transmitters for monitoring and control
of the supply air and exhaust air fans
Note: These signals control vital functions in the CORRIGO. They must always be
connected for correct control function.
C10 and C30
Connect the inputs to pressure switches with voltage-free closing contacts,
for example DTV, or to voltage-free closing contacts in the fan-motor
relays.
C20 and C40
Connect the inputs to pressure transmitters with a 0...10V DC output, for
example DMD or DTL. Wiring, see example in the margin.
The transmitter pressure range is set in the menu ”Settings”, see page 42.
AI3 ochAI4
C10 and C20
AI3 Used for exhaust air temperature sensor, for exampleTG-K3/PT1000.
AI4 Used for extract air temperature sensor or for minimum limiting sensor in
the heat exhanger circuit when using a liquid connected heat exchanger.
(See page 28).
These functions are mutually exclusive, only one of them may be chosen.
C30 and C40
AI3 Used for room humidity transmitter, for example HRT.
AI4 Used for duct humidity sensor (limiting sensor), for example HDT3200.
The sensors must have an output signal of 0...10 V DC corresponding to
0...100% RH.
Since neither of the supply voltage terminals is connected to the AI signal
neutral it is necessary to make an external connection between the supply
voltage pole chosen as G0 and the AI signal neutral.
Note: If no limiting sensor is connected AI4 must be connected to signal
neutral.
AI5...AI8
AI5 Outdoor temperature sensor, for example TG-R6/PT1000.
AI6 Supply air temperature sensor, for example TG-K3/PT1000.
AI7 Room temperature sensor, for example TG-R5/PT1000.
AI8 Frost protection sensor, for example TG-A1/PT1000 when the unit is
configures for water heating.
Input for high temperature limiting switch when the controller is configured
for electric heating. Connect to voltage-free closing contact. (See page 27)

16 Manual CORRIGO C-SERIES 2000.09
DI Digital inputs
CORRIGO has 8 digital inputs, DI1...DI8 for activation of certain functions and input of
external alarm signals.
These inputs may only be wired to voltage-free contacts.
These inputs may only refer to the common DI pole on terminal 22.
Terminal 22 does not have the same potential as other signal neutrals in the
CORRIGO and may not be connected to any other terminals except the DI inputs.
Each input can be individually set, either so that closed contact activates the
function/alarm, or so that open contact activates the function/alarm. See under
menu ”Settings” page 43.
DI1 Input for filter monitor pressure switch(es).
If there are several switches these should be wired in parallell.
DI2 Circulation pump indication.
Must be wired when CORRIGO is configured for water heating.
A stopped pump will force the controller to go into shut down mode.
DI3 Alarm from cooling machine(s).
DI4 Rotation sentinel or ice build-up thermostat in plate exchanger.
DI5 Fire alarm.
DI6 External alarms or external switches not in ”Auto position” (used when
CORRIGO is used with relay module RM6H-24/D or fire damper end position
switches (for fire damper exercising). Function depends on configuration
settings (see page 30).
DI7 Pushbutton or timer for extended running, single speed fan or high speed
when using two-speed fans.
DI8 Pushbutton or timer for extended running, low speed when using two-speed
fans.
Simultaneous closure of both DI7 and DI8 will force the CORRIGO to shut
down.
For installations with external switches for fan control, wire according to the
figures below. DI7 and DI8 should then be configured as for timer.

AO Analogue outputs
Depending on model, CORRIGO has 3...6 analogue outputs,AO1...AO6.
Output signal 0...10 V DC, 5 mA. Short-circuit protected.
These outputs should refer to terminal 41, signal neutral.
Signal neutral G0, terminal 41, in the CORRIGO is internally connected to sytem
neutral on terminal 43.
It is therefore important that any actuators sharing the CORRIGO supply transformer
are wired with their supply neutral connected to the same transformer pole as the
CORRIGO terminal 43.
AO1...AO3 is present in all models. These outputs comprise the temperature control
sequence. The output function is dependant on the configuration settings but the
actuating order is always Y3 beforeY2 before Y1 on increasing heat
demand.
AO1 Y1 - Heating or mixing-dampers.
AO2 Y2 - Heating, Plate exchanger, Rotating exchanger, liquid-connected
exchanger or cooling.
AO3 Y3 - Heating, cooling.

DO Digital outputs
CORRIGO has 7 digital outputs DO1...DO7.
DO7, alarm output is a voltage free closing relay contact. 1A, 24 V AC/DC.
The outputs DO1...DO6 are triac controlled, 0.5A, 24 VAC. Short term 1A.
The triac outputs are paired to common supply terminals for 24 VAC.
See figure in the margin.
For handling higher voltages or currents, use relay modules RM6-24/D or
RM6H-24/D that have been developed for this purpose.
Some of the outputs have alternative functions depending on model and con-
figuration. For example, this means that, in C10 and C30, DX cooling cannot be
combined with control of two-speed fans.
DO1 Start supply-air fan (High speed for 2-speed fan in C10 and C30).
DO2 Start exhaust-air fan (High speed for 2-speed fan in C10 and C30).
DO3 Control of circulation pump or electric heating interlock.
Must be wired when water heater is used. Stopped pump will force the
CORRIGO to shut-down mode.
DO3 is normally used for control of the circulation pump. When using electric
heating, this is not used. Instead it can often be useful with an output for
electric heating interlock, for example when a step-controller is used to
control the heater.
Step-controllers often have step-up/step-down time delay functions.
This can lead to heating output during the cool-down period or even after the
supply air fan has been shut down which will trip the heater high-limit
thermostat.
By wiring the heating relays via DO3 the heating output will be shut down as
soon as CORRIGO switches from running mode to shutdown mode.
When CORRIGO is configured for electric heating DO3 will be active during
normal running mode and switched off in shut-down mode i.e. even during
the cool-down period.
DO4 Control of chiller 1 (DX1) or
Start supply-air fan, low speed for 2-speed control in C10 and C30.
DO5 Control of chiller 2 (DX2) or
Start exhaust-air fan, low speed for 2-speed control in C10 and C30.
DO6 External frost protection interlock or fire damper exercising.

Information series - rolling display
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, output status for the control outputs Y1,Y2 and
Y3 and setpoint, actual value and output status for supply air fan and exhaust air
fan and sepoint and actual value for the humidity control.
The initial display shows the product name, date and time.
Program version number By pressing Esc when the gerneral display is active the
product version number is displayed. For LON-models the 12 digit neuron
ID-number is also displayed
The information menu is started by leaving the main menu by means of Esc or by
leaving the keyboard unused for a ten-minute period. First, the start window will be
shown for 10 seconds and then the three displays shown above will alternate at
three-second intervals.
Main menu
Press the OK button.The information menu will stop and the main menu will open
immediately.
The main menu consists of a number of menu headings and what can be seen and
done is governed by the log-in level of the user, as described below.
When the main menu is opened TEMP CONTROL is always displayed at the top of
the display.
The arrow marker to the left of TEMP CONTROL means that this heading is mar-
ked and pressing the OK button opens this menu and shows its submenus.
Arrows at the right of the display indicate that there are headings above and below
the text that is currently being displayed. Move by using the arrow buttons.
The main menu has the following headings:

Alarms
When alarms are activated they are displayed in the alarm queue and also as a
blinking red light on the display panel on the front of the controller. Certain alarms
cannot be traced to one of the 7 LEDs on the panel and therefore have no separate
alarm on the front. The alarm lamp above the alarm button always blinks red,
however, in the event of an alarm.
Alarm queue
To check the alarm queue press the alarm button . The display will then show
active alarms, the date and time when the alarm became active and the alarm
status.
Alarm status
Blinking ”AL” indicates that the alarm is active and has not been
acknowledged.
Steady ”AL” indicates that the alarm is active but has been acknowledged.
Blinking ”OK” indicates that the alarm has aborted but has not been
acknowledged.
Acknowledging an alarm
Alarms are acknowledged by means of the OK button which will remove the alarm
from the alarm list. If the alarms are still active they will remain in the alarm list but
the blinking will be replaced by a steady ”AL” and a steady red light on the alarm
signals.
Arrows on the right-hand side show when there are more alarms in the queue.
Login
CORRIGO has four different login levels to prevent the user from inadvertently
changing any settings.
0 Without logging in all of the most important parameters can be viewed such
as input and output status, alarms in the alarm queue, setpoints etc. Alarms
can also be acknowledged.
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. Other parameters can be
read off but not changed.
2 Gives access to most setpoints and running parameters such as outdoor
compensation, control alarm deviations, time delays etc.
3 The highest user level giving total access. Used by the commissioning
engineer for system configuration.
