Corrigo E

To use Corrigo E

Each model of Corrigo E is loaded with all applications
(ventilation, heating and boiler control). At the first
start-up, you choose application and language. Thereafter,
the unit should be configured. Inputs and outputs must
be assigned and all relevant parameters must be set to
adapt the application to the current operation mode.

Configuration

Corrigo E can be configured in different ways:

Via the display

Directly on the controller panel in “step-by-step menus”.
Operation status, alarms and values are shown in the
backlit display.

E tool

Corrigo E tool is a PC-based
configuration software with graphical
user interface. The program gives
you a very good overview of the
settings, which will save time.

Using E tool, all settings can be
done on the computer and then
be downloaded to the Corrigo. An
infinite number of configurations can be stored in the
computer memory for later use.

When E tool is used for configuration, a file is saved
which documents the settings. This can easily be
distributed when needed via for example e-mail.

E-DSP

The external display E-DSP can be
ordered with 3 or 10 m cable length.
To handle greater distances than
10 m, E-DSP can also be used
together with the repeaters E0-R and
E0-R230K, for distances up to
1000 m (RS485).

Front panel

Corrigo E has a clear and functional front panel for simple
operation of the controller. All information is shown in
the backlit display.

LEDs

There are two LEDs on the front:

• The alarm LED is marked with a symbol

• The "write enable" LED is marked with a symbol

Buttons

All functions can be configured by using the display
information and buttons on the controller.

Access rights

Corrigo E has four different log on levels.

• Admin – gives full read/write access to all settings
and parameters in all menus.

• Service – gives access to all menus except the
submenus "Configuration"/"In- and Outputs" and
"Configuration"/"System".

• Operator – gives read-only access to all settings and
parameters and write access to all settings and
parameters in all menus except Configuration.

• Basic level – gives read-only access to all settings and
parameters.

Scheduler

Corrigo has a year-based clock function. This means that
a week-schedule with holiday periods for a full year can
be set. The clock has automatic summertime/wintertime
change-over.

The controllers have individual schedules for each
weekday plus a separate holiday schedule.

Holiday period

Up to 24 individual holiday periods can be configured.
Holiday schedules take precedence over other schedules.

Running periods

Each day has up to two individual running periods. For
two-speed fans and pressure controlled fans, there are
daily individual schedules for normal speed and reduced
speed, each with up to two running periods.

Manual control (Manual / Auto position)

Corrigo E and all the configured outputs can be manually
controlled, as well as a number of control functions.

This is a very handy feature which simplifies the
checking of individual functions in the Corrigo. The
supply air controller's output signal can be manually set
(Manual/Auto) to any value between 0 and 100%. The
temperature output signals will change accordingly if they
are in Auto mode.

It is also possible to manually control each of the
temperature output signals individually. All the configured
digital outputs can be set to On, Off or Auto.

Alarm handling

If an alarm condition occurs, the alarm LED on the front
panel on units with display will start flashing. The LED
will continue to flash as long as there are unacknowledged
alarms. Alarms are logged in the alarm list. The list shows
type of alarm, date and time for the alarm and the alarm
class (A, B or C alarm).

Alarm classification

Class A and B alarms will activate alarm output(s) if these
have been configured.

Class C alarms do not activate the alarm output(s). These
alarms are removed from the alarm list when the alarm
input resets, even if the alarm has not been acknowledged.

Alarm log

For the ventilation and heating applications, the latest
40 alarm events are listed under ”Alarm events” in the
display.

Corrigo E

Menu information

With E tool connected to Corrigo E you can add free
text in the first line of the start-up screen. As an example,
you can give the controller an identity. There are also five
different menu alternatives for other information. Corrigo
E also has an information screen where all 4 rows can be
used. You can for example display contact information
etc.

Corrigo E with communication

The basic version of Corrigo E is equipped with an
RS485 port for connection via EXOline or Modbus. As
an option, the controllers can be delivered with ports for
TCP/IP or LON communication. This makes it possible
to use Corrigo E in existing networks, and to supervise
the application via the Internet, a mobile unit, or a local
computer.

Connection via LAN/Internet gives excellent possibilities
for adjusting set points, storing settings and supervising
the functionality of the installation.

Connection of expansion units

In order to expand the number of I/Os on a controller,
up to two Corrigo E units can be connected to models
with two ports. The maximum number of inputs/
outputs is 3*28 = 84 I/Os. Port 2 can also be used for
communication with two Vacon NXL, Lenze, Omron
V1000 or Emerson Commander frequency converters.
A frequency converter and an expansion controller can
be connected to the same port. Control and sending of
alarms from the frequency converters takes place via
Modbus communication.

Corrigo E models with two ports are available in models
with port 1 as RS485 (E...2-S) or TCP/IP (E...2-S-WEB).
They have 15 or 28 I/Os. See the model overview on page

11.
Any Corrigo E controller can be used as expansion unit.

However, units without display are normally utilised since
no information is shown in the display of the expansion
unit.

Modbus communication

The basic version of Corrigo E can be changed to
communicate with Modbus RTU via the RS485 port.

When Modbus has been activated, Corrigo E
automatically senses if communication is taking place via
Modbus or EXOline (with E tool).

Models with LON communication

Models with LON use LonWorks, adjusted according to
the LonMark-guidelines. See separate network variable
list LON.

LON communicates via the LON port on Corrigo E. The
configuration takes place in the display of the controller
or via E tool on a PC connected via the RS485 port on
Corrigo E. Corrigo E should be installed in the LON
network with the help of LonMaker or a corresponding
computer program.

LON communication is not yet available for boiler
application.

LON can also be used in combination with expansion
units. In this case, expansion unit 1 should be a
Corrigo E-LON.

Which LON files are to be used for the controller is
shown in the display.

Corrigo Web (with TCP/IP port)

E...-WEB models communicate via TCP/IP and use the
TCP/IP port instead of the RS485 port on Corrigo E. This
communicates with EXOline via TCP/IP.

To connect Corrigo E to a PC and the configuration tool
E tool, a special network cable, E-CABLE-TCP/IP, should
be used. This is a crossover network cable.

Corrigo E

Corrigo Web

The E...-WEB models has an integrated web server, which
is easy to commission and configure using E tool.

The web server automatically puts required information
and values on the website, depending on the configuration
of the application in Corrigo E (which functions are used,
inputs and outputs etc.). There are also real-time diagrams
available on the website for 3.0 versions and up.

Corrigo E with integrated web server can be used in
internal intranet solutions as well as externally towards
the Internet. If you want to connect the controller to
the Internet, you need broadband Internet access. The
ventilation and heating applications have this web server
function. However, Corrigo Web for application boiler
control is not yet available.

Below are examples of what the website looks like for
Corrigo Web.

Regin Building Access

Regin Building Access is a general application for the
operating system Android which makes it possible to
access a Regin controller with TCP/IP communication
via e.g. a mobile network or a Wi-Fi network.
Once connected, you can view parameters, alarms,
documentation, etc. from the controller in the form of
lists.

The application is intended to be run on a mobile phone,
however can also be used on an Internet tablet. Regin
Building Access can be downloaded free of charge from
Android Market.

Corrigo E

Digital temperature control

• Heating / DX-cooling

As alternative or complement to the above mentioned
analogue control, heating and cooling can be activated
in steps. The internal signal is then used to activate
digital outputs for control of the heaters/chillers. Up to
four heating outputs and three cooling outputs can be
configured.

The outputs can be set to sequential or binary control.
At binary control, the analogue heating and cooling
outputs can be set to 0...100 % between every step for
equalization purposes.

Outdoor temperature dependent, individual blocking of
DX cooling steps is possible.

The fan speed can be overridden to normal speed when
using DX cooling.

When using aftercooling in units with an electric heating
coil, the heat exchanger will continue to run.

Digital time-switch

Up to 5 digital outputs can be used as timer controlled
outputs. Each timer channel has a separate scheduler with
two periods per weekday. These outputs can be used to
control lighting, doorlocks etc.

Support control

When running room temperature control or extract air
control (with a room sensor connected), “Support control
Heating” or “Support control Cooling” will run.

• Support control heating

• Support control cooling

• Recirculation damper

• Stopped extract fan can be selected

Free cooling

This function is used during the summer to cool the
building during the night using cool outdoor air.

Temperature control

The temperature controller is based on a supply air
PI-controller for heating control with a pre-programmed
set of control modes. The controller uses data from
sensors etc. to control a number of different control
functions, as well as various input and output functions.
The user can choose which functions are to be used, the
only restriction is the physical number of inputs and
outputs of the different models.

Corrigo E has achoice of the following control modes:

1. Supply air control

2. Outdoor temperature compensated supply air
control

3. Cascaded room temperature control

4. Cascade connected extract air temperature control

5. Outdoor temperature dependent switching between
room control and supply air control

6. Outdoor temperature dependent switching between
extract air control and supply air control

Applications Heating - Cooling - VVX - Dampers

Output functions which can be controlled by Corrigo E.

Analogue temperature control

Humidity control

Humidity control can be configured as:

• Humidification

• Dehumidification

• Humidification/Dehumidification
Two humidity sensors can be connected, a room sensor
for control and a duct sensor for maximum limiting.

The humidity sensors must give 0…10 V for 0…100%
RH.

Fan control

Fans can be 1-speed, 2-speed or frequency controlled. For
frequency controlled fans there are a number of options:

1. Constant pressure: The pressure signal from a

pressure transmitter is kept constant by frequency
controlling the fan.

2. Constant flow: The flow m3/h is calculated using

a signal from the pressure transmitter. The flow is
kept constant by frequency controlling the fan. The
supply and extract air fans have individual conversion
parameters for calculation of their respective flow.

3. Manual output to fixed values: Pressure signals are

not used. Instead, the output signal for the frequency
converter is set to a fixed value.

4. External control signal: Direct control of both SAF

and EAF with external 0...10 V control signals for
integration with VAV systems.

5. Frequency control SAF with EAF slave: Frequency

and pressure controlled supply air fan with frequency
controlled extract air fan. The EAF output follows
the SAF output.

6. Frequency control SAF with flow controlled EAF:

Frequency and pressure controlled supply air fan.
The extract air fan flow is controlled by the flow in
the supply air fan.

Air flow compensation for frequency controlled fans

Compensation can be set for both the supply air fan and
the extract air fan, or the supply air fan only. Air flow
compensation can be based on the supply air, extract air
or room temperature.

Cont. Control and functionality: Ventilation control

Blocking of automatic restart at power-up

Restart at power-up can be blocked. However, as default
the unit is set to start automatically.

Demand controlled ventilation

In applications with varying occupancy, the fan speeds
or mixing dampers can be controlled by the air quality,
which is measured with a CO2/VOC-sensor.

control.

• Heating circuit

• Exchanger circuit, liquid connected exchangers

• Cooling circuit

Damper control

Control possibilities:

• Close-off dampers

• Return air damper

• Extract air damper control

• Fire dampers

• Fire damper exercising

The close-off damper can be controlled individually or
together with Return air damper / Extract air damper.

Extended running

Digital inputs can be used to force the unit to start
although the timer says the running mode should be
“Off”. These input signals have higher priority than the
internal timer channels.

Recirculation function

Function for distributing the air in the room using the
supply air fan, with or without temperature control.

Alarms

Alarm log in the display which shows the 40 latest alarm
events.

Change-over
