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.

 

OK

C

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

This function is useful in Southern Europe where the 
reverse function of free cooling is desired. The function 
can be used to heat a building in the morning if the 
outdoor temperature increases faster than the indoor 
temperature and heating is required.

Cooling recovery

If the extract air temperature is lower than the outdoor 
temperature, cooling recovery can be activated. 

Enthalpy control

 

Override the signal for mixing dampers if the outdoor 
enthalpy is higher than the indoor enthalpy for increasing 
re-circulated air.

Heat exchanger efficiency monitoring

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 m

3

/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.

Corrigo E

Control and functionality: Boiler control

Example of boiler control

In this application, Corrigo E can be used for boiler 
control as well as heating and domestic hot water control. 
The controller uses data from sensors etc. to control a 
number of 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. 

Boiler control

One boiler control circuit (one main sensor) with 1...4 
boiler vessels, each with single or double burners (on/off). 
Boiler 1 can have analogue control (0...10 V).
Two control modes: modulating PI-control or thermostat 
control (fixed starting and stopping points for each 
vessel).
The boiler circuit setpoint can be a fixed temperature, 
an outdoor temperature dependent setpoint (curve) or a 
heating circuit temperature dependent setpoint.
The boiler control has automatic malfunction take-over, 
with multiple boilers the starting order can be fixed, 
run-time controlled or alternating.
Common boiler pump or individual pumps for each 
boiler vessel, with start/stop and settable automatic pump 
exercising.
The boiler return temperature can be limited to eliminate 
the risk of condensation as a result of low temperature.

Heating circuits

Can be configured for 1 to 3 heating systems, which are 
controlled by PI-controllers with settable P-band and 
I-time. 

Control curves/Outdoor compensation

The controllers have individual outdoor temperature / 
supply temperature control curves. 

Adaption of curves

Room sensors can be used to correct the control curves. 
The average room temperature error over 24 h is 
calculated.

and the pump will run.

Wind compensation

To compensate for wind chilling, it is possible to connect 
a wind sensor and generate a setpoint displacement.

Building inertia

The building inertia, i.e. the building heat storage 
capacity, is settable to one of three levels. The set inertia 
dictates the influence of outdoor temperature.

Night set-back

Set in room temperature degrees. The Corrigo has 
individual schedules for each heating system with two 
comfort-temperature periods per day.

Start time optimizer

Function for automatically calculating when the 
night set-back should stop in order to reach a pre-set 
temperature at the time set for start of comfort time 
in the internal scheduler. Autodidact function. A room 
sensor is required when this function is used.

Power limitation

Using a digital input the power to the heating systems can 
be temporarily restricted. 

Domestic hot water

Can be configured for one domestic hot water circuit, 
HW1, which has constant supply-temperature control 
and is controlled by PID-controllers with settable P-band, 
I-time and D-time.

Corrigo E

Night set-back

Individual schedules for the hot water system with two 
normal temperature periods per day. 

Pump control

Corrigo E has a digital output signal which can be used to 
control the hot-water circulation pump in HW1. 

Periodic overheating

Once daily, the temperature setpoint can be increased to 
62°C to prevent growth of Legionella bacteria.

Storage tank

A storage tank function can be enabled. The storage tank 
load pump, P1-HP1, is started depending on the storage 
tank supply water and return water temperatures.

Pressure control

Corrigo E can , using an analogue output signal, control 
a variable speed pump to maintain a constant settable 
pressure. 

Cold water monitoring

Monitoring of the cold water usage. 

The following values 

are calculated:

•    24 hour usage in litres, today 
•    24 hour usage in litres, yesterday 
•    24 hour usage in litres, day before yesterday 
•    Lowest hourly usage in litres, today 
•    Lowest hourly usage in litres, yesterday 
•    Usage total in m

3

. The value can be reset. 

•    Water-flow (litres/min)

Alarm types

  •  Pulse error / High usage / Leakage control

Energy monitoring

One digital pulse function can be configured for heating 
energy monitoring. The pulse constant is settable. 

The following usage values are calculated:

  •  24 hour usage in kWh, today 

•  24 hour usage in kWh, yesterday 
•  24 hour usage in kWh, day before yesterday 
•  Total usage in kWh/MWh. The value can be reset.

Power values

Heating power is calculated by measuring the time 
between the energy pulses. The following power values 
are calculated: 
  •  Instantaneous value for a certain time or after a    

 

certain number of pulses 

•  Average of the above instantaneous value. 
•  Maximum value for the above instantaneous value. 

Leakage monitoring

Once a week, the control valves will be closed and the 
energy usage measured for a preset time. An alarm is 
generated if the energy leakage is larger than a settable 
value. 

Electricity meter

One digital pulse function can be configured for heating 
energy monitoring. The pulse constant is settable.

Usage values

Total usage in MWh. The value can be reset.

Timer channel outputs

Up to 5 digital outputs can be used as timer controlled 
outputs. Each timer has its own scheduler with two 
activation periods for each day of the week and a 
year-based holiday calendar.

Cont. Control and functionality: Boiler control
