Chapter 2 About Corrigo E
Corrigo E for heating is a complete new range of programmable controllers for control of building
heating systems.
Corrigo E series for heating comprises three model sizes: 8, 15 or 28 in-/outputs.
Available with or without front panel display and buttons. For units without front panel display and
buttons a separate, cable-connected terminal E-DSP with display and buttons is available.
All programming and normal handling can be done using the display and buttons or from a
connected computer running Corrigo E-tool.
The temperature controllers are PI-controllers for heating control and tap hot-water control with a
pre-programmed set of control modes. To the controllers can be bound a number of different control
functions and analogue and digital input and output functions. The choice of which functions are to
be used is free, the only restriction lying in the physical number of inputs and outputs that the
different models have.
The Corrigo is designed for DIN-rail mounting.
The program for a heating unit contains, apart from other things, the following functions:
Heating sequence control:
Control of 1 - 3 individual heating circuits.
Tap hot water control:
1 or 2 tap hot water circuits and 1 storage-tank charger circuit.
Differential pressure control
One constant differential pressure control circuit
Boiler control
Basic two step boiler control.
Timer outputs
Up to 5 individually settable timer outputs for control of, for example, lighting, door locks etc.
Timer control
Year-base clock, individual schedulers, holiday scheduler.
Water consumption
Energy consumption

Chapter 3 Installation and wiring
3.1 Installation
Corrigo E can be mounted in a DIN-standard casing (minimum 9 modules), on a DIN-rail in a
cabinet or, using a suitable front-mounting kit, in a cabinet door or other control panel.
Ambient temperature: 0…50°C.
Ambient humidity. Max. 95 %RH, non-condensing.
3.2 Wiring
At the end of this chapter there are wiring diagrams showing the factory set configuration. We have
also included blank diagrams. Since the function of most of the inputs and outputs depends on the
programming of the unit the final wiring diagram cannot be filled in until the installer has decided
how to use the inputs/outputs. It is important to make sure that the wiring is correctly done and in
accordance with the instructions given in this manual.
3.2.1 Supply voltage
24 V AC ±15%, 50/60 Hz. 6 VA
If the Corrigo E and the actuators connected to it share the same transformer it is essential that the
same transformer-pole is used as reference for all the equipment. Failure to do so will prevent the
equipment from functioning as intended and may also lead to damages.
3.2.2 Inputs and outputs
The list of input and output functions in section 3.2.3 is a handy instrument to help you keep track
of which inputs and outputs you will need to configure.
Analogue inputs
Analogue inputs must refer to an A-gnd terminal placed in the same terminal block as the input
being wired.
Analogue inputs can, depending on the configuration, be used for either PT1000 temperature
sensors or for 0…10 V DC analogue input signals, for example from a pressure transmitter.
Digital inputs
Digital inputs must refer to C+ on terminal 4. Digital inputs may only be wired to voltage-free
contacts. Any external voltage applied to a digital input may harm the unit.
Universal inputs
A universal input can be configured to act as either an analogue input or as a digital input.
A universal input configured as analogue input must refer to an A-gnd terminal placed in the same
terminal block as the input being wired.
A universal inputs configured as an analogu e input can, dep ending on the con figuration, b e used for
either PT1000 temperature sensors or for 0…10 V DC analogue input signals, for example from a
pressure transmitter.
A universal input configured as a digital input must refer to C+ on terminal 4. It may only be wired
to voltage-free contacts.
Corrigo E Heating manual, revision G Chapter 3 Installation and wiring 9
Analogue outputs
Analogue outputs must refer to the A-gnd terminal placed in the AO terminal block.
All analogue outputs can be individually set to any one of the following signals:
0…10 V DC
2…10 V DC
10…0 V DC
10…2 V DC
If the Corrigo E and the actuators connected to it share the same transformer it is essential that the
same transformer-pole is used as reference for all the equipment. Failure to do so will prevent the
equipment from functioning as intended and may also lead to damages.
Digital outputs
Digital outputs must refer to G on terminal 10.
All the digital outputs are triac controlled. The outputs will deliver 24 V AC, 0.5 A continuous. The
outputs cannot be used to drive DC relays.

Corrigo E Heating manual, revision G Chapter 4 Commissioning 15
Chapter 4 Commissioning
General
Before the Corrigo can be used it must be configured, inputs and outputs must be assigned and all
relevant parameters must be set.
All commissioning can be done using the Corrigo front panel display and buttons or using the
display unit E-DSP.
Corrigo E-tool
The best way however, is to configure the Corrigo E by using Corrigo E-tool.
Corrigo E-tool is a PC-based configuration program specially developed to simplify the
commissioning of the Corrigo E-series.
When using E-tool the whole configuration and all settings can be done on the computer and then
downloaded to the Corrigo. An infinite number of different configurations can be saved in computer
memory for later use.
4.1 How to do it?
For configuration using E-tool, see the E-tool manual.
For configuration using the front panel there are two ways to go depending on how much help you
need.
Option 1:
• Jump straight to chapter 6 and 7, Display, buttons and LEDs and Access rights.
• After mastering the button and menu system, connect power to your Corrigo, log on at
System level and go to the menu Configuration.
• For the time being, skip the configuration menu Inputs/Outputs and start by configuring
Control functions.
• Run through the configuration menus in order and set whatever functions and parameters
you wish to include. Use chapter 4 of this manual for reference. Keep track of which inputs
and outputs you will need. To help you, there is a list of input and output functions
provided in chapter 3, (3.2.3 Input / Output list.)
• Finally, configure Inputs/Outputs.
• Exit Configuration and go to Settings
• Set the control values in Settings
• Set the clock and scheduler functions in Timers.
• Set the control setpoints in Actual/Setpoint.
Your Corrigo should now be ready to run.
Option 2:
Read this manual in the order given below: The manual has been designed to act as a guide through
the commissioning. The last chapters of the manual, not listed below, cover menus and function s
that are not used during commissioning.
Corrigo E Heating manual, revision G Chapter 4 Commissioning 16
Functional description
Start by reading the chapter 5. Functional description below. Some functions are essential to the
working of the unit and must be included. Others are more of the nature of optional extras which
can be excluded.
At the end of each function description there is a table of the necessary inputs and outputs to
implement the function. At the end of the manual there is a list of all the analogue and digital inputs
and outputs. As you read, mark in the list the inputs and outputs you will be using for the
application you are building. Note that the universal inputs in Corrigo E28 can, individually, be
configured as either analogue or digital inputs.
Display, buttons and LEDs
Read chapter 6 on how to use the front panel buttons to navigate the Corrigo E menu system.
Access rights
Chapter 7. Learn how to log in on the Corrigo E.
Configuration
Chapter 8. Configuration.
Connect power to the Corrigo. Using the buttons and menu system, go through th e configuration
menus covering the functions yo u wish to use.
On delivery the units already have the inputs and outputs assigned to various functions. These can,
of course, be changed. In chapter 3 Installation and wiring there are two sets of wiring diagrams,
one set showing the pre-configured input / outpu t configuration and one set where you can fill your
own configuration choices.
Settings
Set the control parameters, P-band, I-time for the temperature control loops in use.
Set the alarm parameters; alarm levels and delay times.
Timer settings
Set the clock and calendar functions
Setpoints
Set all the setpoints for all active control loops.
Hand/Auto
Learn to use manual control. Very useful for testing out your system.
Corrigo E Heating manual, revision G Chapter 5 Functional description 17
Chapter 5 Functional description
5.1 Heating systems
5.1.0 General
Corrigo E can be configured for 1 to 3 heating systems (radiator groups), HS1, HS2 and HS3.
5.1.1 Controllers
The heating system controllers are PI-controllers with settable P-band and I-time.
5.1.2 Control curves
The controllers have individual outdoor temperature / supply temperature control curves.
Each curve has 8 fix points. The default setting of the outdoor temperature values for the fix points
are -20, -15, -10, -5, ±0, +5, +10, +15. These can not be changed using the Corrigo front panel but
can be changed using E-tool. The corresponding supply temperature values ar e settable using the
front panel or E-tool.
5.1.3 Adaptation of curves
Room sensors can be used to correct the control curves. The average room temperature error over
24 hours is calculated. Values 1 hour befo re and 1 hour after a day/night or night/day change-over
are ignored. The curves are corrected once daily using the average room temperature error and a
settable correction factor. The correction will be a parallel displacement of the entire curve using the
following formula:
Displacement = (Room setpoint - Average temp)*Factor
5.1.4 Pump control
Each system can have single or double pumps. Double pumps are run one at a time with auto matic,
weekly change over and automatic start of the backup pump on malfunction of the active pump.
Outdoor temperature dependent pump stop can be configured.
Pumps are exercised for 5 minutes at 3 pm daily.
5.1.5 Frost protection
If a controller is set to Off or Man(ual control) and the outdoor temperature is below a settable value
a minimum, settable supply temperature will be maintained and the pump will run.
5.1.6 Wind compensation
To compensate for wind chilling it is possible to connect a wind sensor and generate a setpoint
displacement according to a settable factor (°C per m/s).
Corrigo E Heating manual, revision G Chapter 5 Functional description 18
5.1.7 Building inertia and boost
The building inertia is settable to one of three levels: None, Medium, High.
The set inertia dictates the influence of outdoor temperature.
With no inertia, the outdoor temperature is used directly, with medium inertia a one-hour average is
used and with high inertia a 12-hour average is used.
Boost is used to speed up the raising of the indoor temperature when switching from night set back
temperature to normal comfort temperature. This is done by temporarily displacing the supply
temperature set-point curve. The following conditions must be met:
• Average outdoor temperature lower than 1 7° C
• Supply set-point value higher than 25°C
• Night set-back more than 2°C (room temperature)
The displacement is calculated as follows:
Displacem.=Factor*(17 - outdoor temp)*night set-back
Where Factor is settable 0…10 where 0 gives no boost and 10 gi ves hig h b oost.
The time in minutes that boost will be active is calculated as follows:
Time = 1.6*(17 - Outdoor temp)
Time is limited to maximum 60 minutes.
5.1.8 Night set-back
Lowering of the night temperature is set in room temperature degrees. The corresponding lowering
of the supply temperature is calculated by the controller by multiplying the value by 3. The Corrigo
has individual schedules for each heating system with two comf ort-temperature periods per day.
5.1.9 Power limitation
Using a digital input the power to the heating systems can be temporarily restricted. When activated,
the setpoints are lowered by a settable factor (% relative to 20°C). The limitation applies to all
configured heating systems.
The limitation is calculated as below:
Limited setpoint=20+(Setpoint-20)*Factor/100
Factor 100 gives no setpoint reduction, 0 gives full reduction to 20°C.
5.2 Tap hot water
5.2.0 General
Corrigo E can be configured for one or two tap hot-water systems HW1 and HW2. These have
constant supply-temperature control.
5.2.1 Controllers
The heating system controllers are PID-controllers with settable P-band, I-time and D-time.
5.2.3 Night set-back
The Corrigo E has individual schedules for each hot water system with two normal-temperature
periods per day.
Corrigo E Heating manual, revision G Chapter 5 Functional description 19
5.2.4 Pump control (HW1 only)
Corrigo E has a digital output signal that can be used to con trol the hot-water circulation pump in
HW1. The pump will run according to the settings of the night set-back sch edule, running during
normal temperature periods and standing still during periods with reduced temperature.
5.2.5 Periodic overheating
Once daily, at 02:00 am the temperature set-point can be increased to 62°C to prevent growth of
Legionella bacteria. The raised set-point is maintained until the supply temperature reaches 60°C
but not shorter than 1 minute and not longer than 5 minutes. If the pump is stopped it will start and
run for the duration of the overheating pe ri o d pl us 2 minutes.
5.3 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.
Loading is started if the return water temperature is lower than the set start temperature.
Loading is stopped when the supply temperature is higher than the set stop temperature and the
return temperature is higher than the set start temperature + the set differential.
5.4 Pressure control
Corrigo E can, using an analogue output signal, control a variable speed pump to maintain a
constant settable pressure. A digital output signal is available to give a start signal to the frequ ency
converter. This output is enabled as soon as the converter control signal rises above 0.1 V.
5.5 Boiler control
A simple boiler control can be enabled.
When the boiler temperature falls below Start temperature 1 the digital signal Start 1 will be
activated. Should the temperature fall below Start temperature 2 the digital output Start 2 will be
activated.
Any active outputs will be deactivated when the boiler temperature rises above the set Stop
temperature.
5.6 Cold-water monitoring
One or two circuits monitoring the cold-water usage can be configured each using a digital pulseinput from a water meter. The pulse constant is settable. Maximum pulse rate is 2 Hz.
5.6.1 Values
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 is resettable
• Water-flow (litres / min)
Corrigo E Heating manual, revision G Chapter 5 Functional description 20
5.6.2 Alarms
Pulse error If no pulses are detected within a settable time an alarm is activated. Setting
the time to 0 inhibits the alarm function.
High usage If the daily usage is higher than a settable value an alarm is activated.
Leakage control If the lowest hourly usage during the previous day is higher than a settable
value an alarm is activated.
5.7 Energy monitoring
One digital pulse function can be configured for heating energy monitoring. The pulse constant is
settable.
5.7.1 Usage values
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 or MWh. The value is resettable
5.7.2 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 for the last hour
• Maximum value for the above instantaneous value
5.7.3 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, default 3000 W. The time for
and duration of the leakage monitoring is settable. Default is Sundays at 2:00 am for 30 minutes.
5.7.4 Alarms
Pulse error If no pulses are detected within a settable time an alarm is activated. Setting
the time to 0 inhibits the alarm function.
High usage If the daily usage is higher than a settable value an alarm is activated.
5.8 Electricity meter
One digital pulse function can be configured for electricity energy monitoring. The pulse constant is
settable.
5.8.1 Usage values
Total usage in MWh. The value is resettable.
Corrigo E Heating manual, revision G Chapter 5 Functional description 21
5.9 Timer channel outputs
Up to 5 digital outputs can be used as timer controlled outputs.
These can be used for controlling, for example, door locks, lighting, laundry-room equipment etc.
Each timer has its own scheduler with two activation periods for each day of the week and a yearbased holiday calendar.

8.14.8 Alarm forwarding via SMS
Via a connected GSM modem, Corrigo can send an alarm message to up to 3 different recipients.
To use this function, you first have to purchase a lock-up code from Regin. When there is an alarm,
Corrigo sends an alarm message to the first number on the list. The message consists of an alarm
text, the unit name (the same text that is shown in the first row of the start display) and the time
when the alarm occurred. If the recipient does not send an SMS within 5 minutes to confirm that the
message has been received, Corrigo will send the message to the next number on the list.

Chapter 11 Actual / Setpoint
In this menu group all actual current values and setpoint values are displayed and, providing a
sufficiently high log on level is used, all setpoints can be changed.
The following menus are available providing that the corresponding input is activated.
11.1 Setpoint Heating systems HS1, HS2 and HS3
Outdoortemp: 18.4°C

Setp: 20.0°C
Submenu: Setpoint
In-between-values are calculated using straight lines between breakpoints. Setpoints for
temperatures lower than the lowest breakpoint and higher than the highest breakpoint are calculated
by extending the line between the two last breakpoints at either end. Example: At the lower end the
setpoint is increasing by 14°C for every 5 °C lowering of the outdoor temperature. So the setpoint at
–23°C would be 77+3/5 * 14°C = 85.4°C.

General
In this menu the running mode of the un it and all the configured outputs can be manually controlled.
This is a very handy feature which simplifies the checking of individual functions in the Corrigo.
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.
Since leaving any of the outputs in manual control will disrupt the n ormal control, an alarm will be
generated as soon as any output is set to a manual mode.
Since the menus vary according to the configuration of the outputs only the most common ones will
be shown here. For the digital signals you can normally choose between Auto and On and Off or
similar words indicating the two possible manual states of the digital output.

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)
To access the alarm list, press the alarm button, the front panel button with the red button-top.

If there are multiple alarms, this is indicated by up / down arrow symbols at the right-hand edge of
the display.
Use the UP and DOWN buttons to access the other alarms.
At the left end of the bottom display line the alarm status is shown. For active, un acknowledged
alarms the space is blank. For alarms that have reset the text: “Reset” is shown., Acknowledged,
still active or blocked alarms are indicated by Acknowledged or Blocked.
Alarms are acknowledged by pressing the OK button. You are then given the choice of
acknowledging the alarm or blocking the alarm.
Acknowledged alarms will remain on the alarm-list until the alarm input signal resets.
Blocked alarms remain on the alarm-list until the alarm has reset and the block has been removed.
New alarms of the same type will not be activated as long as the block remains.
Since blocking alarms can be potentially hazardous, you need a high log on authority to block
alarms.
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).
Class C alarms are removed from the alarm list when the alarm input resets even if the alarm has not
been acknowledged.
14.2 Revision numbers
If RIGHT is pressed once when the start-display is shown, see section 8.14.2, a menu showing the
program revision number and id-number will be displayed.
14.3 Free text
If RIGHT is pressed twice when the start-display is shown, see section 8.14.2, a menu showing text
of your choice is displayed. The text can be used to show information concerning the
commissioning company, name and phone number to service personnel etc. Text is entered using Etool. Up to 4 lines of 20 characters can be entered.
