About Corrigo
Corrigo is a series of pre-programmed, configurable controllers for different applications. The Corrigo series comprises three model sizes: 8, 15 or 28 in-/outputs. The controllers are available with or without a front panel display and buttons. For units
without a display and buttons, a separate, cable-connected terminal (E3-DSP) with display and buttons is available.
All normal handling can be carried out using the display and buttons or by using E tool
©
, a software tool that runs on a computer connected to the controller with an E-CABLE model communication cable or a crossover network cable.
Ventilation application, overview of functions
The controller comes loaded with programs for control of a ventilation unit. The temperature controller is based on a supply air PI-controller for heating control with a pre-programmed set of control modes. A number of different control functions as well as analogue and digital input and output functions can be bound to this controller. Certain functions are necessary, while others can be considered optional. This flexibility means that what is shown in the display may differ from one unit to another, depending on which functions have been selected.
Functional choices are not made in the operator level, but in the Admin access level by educated personnel with specialised knowledge. The same applies to other configuration. The program for an air handling unit contains, apart from other things, the following functions:
Different temperature control modes:
• Supply air temperature control, with or without outdoor temperature
compensation.
• Room temperature control (cascade control).
• Extract air control (cascade control).
• Seasonal switching between supply air temperature control and room/extract air
temperature control.
• Outdoor compensated room/extract air control.

• Extra, separate temperature control circuit for after-heaters, etc.
• Extra control sequences Y4 and Y5 (in addition to Y1, Y2 and Y3) for free
integration into the contro lle r output.
With control of:
• Heat exchanger (liquid connected, plate or rotating) or mixing dampers.
• Heating coil: Water with or without fro st protection or electric with high
temperature limit switch.
• Cooling: Water or DX cooling in up to 3 steps.
• Circulatio n pumps for heating, exchanger and cooling.
• Recirculation dampers.
Fan control
• 1- or 2-speed supply air and extract air fans.
• Frequency controlled supply and extract air fans with pressure or flow control,
manual control or external control from a VAV system.
• Pressure controlled supply air fan with slave connected extract air fan (output
dependent or flow dependent) or opposite function (pressure controlled extract air fan with slave connected supply air fan, out put dependent or flow dependent).
Humidity control
Either humidification or dehumidi fication, or both humidification and dehumidification, can be used.
Timer control
For starting and stopping the unit. Up to 5 timer outputs for control of external functions such as lighting, door locks etc.
Demand controlled ventilation
In building s with strongly va rying occupancy the fan speeds or mixing dampers can be controlled by the air quality measured by a CO
2
sensor.
Support control
When using the control function ro om control or extract air temperature control, it is possible to utilise support-heating and/or support-cooling.
Free cooling
When this function has been activated it is used during the summer to cool the building during the night by using cool outdoor air, thereby reducing cooling needs during the day.
Free heating
If the outdoo r temperature is higher than the indoor temperature and there is a hea ti ng demand, the recovery damper will not open for recovery but instead open fully for outdoor air. This may occur during low night-time outdoor temperatures, when the room has been cooled considerably and the outside heat is rising faster than indoors. This function is activated at the same time as “Free cooling”.

5
Enthalpy control
Measures and compares the energy content (enthalpy) of the outdoor air and the extract air (temperature and air humidity). When this function is active, the mixing damper signal wil l be overridden to recirculation if the outdoor enthalpy is higher than indoors.
Pretreatment
Damper and pump control for preheating or precooling of the outdoor air via an underground intake channel.
Cooling recovery
If the extract air is colder than the outdoor air and cooling is required , the heat exchanger control is reversed in order to return the cool extract air.
Recirculation control
Recirculation of air using a supply air fan and (optionally) extract air fan and a recirculation damper with or without temperature control. Used as a recovery function or during heating with support control during the night. Recirculation control is available as an analogue or a digital function.
Step controllers Heating/Cooling
As an alternative to the analogue control of ”Actuator heating Y1” or ”Actuator cooling Y3” step controllers can be used for controlling heating or cooling in steps using digital control.
Change-over
In 2-pipe systems where a combination heater/cooler is operating together with a heat pump, Change-over is a function that enables using the same pipe for both heating and cooling, depending on which is currently required . It uses the output Y1 Heatin g/Y3 Cooling.

The menu system
Navigating the menus
The choice of access level/user access determines which menus are shown.
The display to the left is normally shown at start-up and is located at the basic level of the menu tree. The appearance of the start display may vary since there are 5 types to choose from during configuration. The text in the first row can also be changed using E tool

.
Sp and Av are setpoint and actual value for the supply air controller. This also applies when using cascaded room temperature or extract air temperature control. Actual value = The current measured temperature. Setpoint value = The desired configured temperature.
Pressing ARROW DOWN will move you through t he menu choices at this, the lowest level. ARROW UP will move you back t hrough the choices. Which menus are shown depends on which access level you are using (see the section Access rights for more information about logging on to higher levels).
The basic access level, the level normally active when you have not logged on, only shows a limited number of menus and submenus:
Running mode
Here, you can view and set the unit’s running mode, as well as view selected control functions and alarm events .
Temperature, Air control and Humidity control
Here, relevant values and setpoint values are displayed. Setpoints can only be changed if you have Operator access or higher.
Time settings
Here, the time, date and set running times are shown. Values can only be changed if you have Operator access or higher.
Access rights
Here, you can log on to a higher level, log off to the basic level and change the password.
A user with Normal access, the basic level, can view a limited sele ction of menus. The unit’s running mode can be changed and alarms acknowledged.
If you have Operator access, you can access more information and change other operation parameters like setpoints and time functions.
To get to the next menu level, use ARROW UP and ARROW DOWN to place the d isplay marker opposite the menu you wish to access and press ARR OW RIGHT. If you have sufficient log on privileges the displa y wil l change to the menu you have chosen. At each level there may be se veral new menus through whic h you may move using the ARROW UP and ARROW DOWN buttons.

There are sometimes further submenu s linked to a menu or menu item. This is indicate d by an arrow symbol at the right-hand edge of the display. To choose one, use ARROW RIGHT again. To go to a previous menu level, press ARROW LEFT.
Change parameters
In some menus there are parameters that can be set. This is indicated by the yellow LED with flashing.
A quick blinking (2 times/s) indicates that the parameter can be changed using the present user access. A slower blinking (1 time/s) indicates that a higher user access is required to change the parameter.
To change a pa rameter, first press the OK button. If you need a higher user access than you have to change the parameter, a log on menu will be displayed, see below. Otherwise, a cursor will appear at the first settab le value. If you wish to change the value , do so by pressing the ARROW UP and ARROW DOWN buttons.
In numbers co ntaining several digits you can move between the digits us ing the ARROW LEFT/RIGHT buttons.
When the desired value is displayed press OK. If there are further settable values displayed the cursor will automatically move to the next
one. To pass a value without changing it, press RI GHT. To abort a c hange and return to the initial setting, press and hold the C-button until the c ursor
disappears. Collected here are a number of menus showing running mode, selected functions, alarm
events and status of inputs and outputs.
Running mode
Running mode unit
The unit’s ru nning mode can be changed wit hout logging on.
The running mode can be set to Auto, Off, Manual reduced run or Manual normal run. The Auto mode should normally be used.
Off can be used to stop the unit for service and similar. Manual normal run or Manual reduced run will start the unit even if the timer says that th e running mode should be “Off”.
If the runni ng mode is set to Off, Manual normal run or Manual reduced run, a C ala rm is activated: Running mode Manual. The alarm automatically resets when the running mode is set to Auto again.

Selected functions
In these menus, you can see how some of the most important functions have b een configured. Changes cannot be made.
Heater, exchanger and cooling type. If one of the functions is not used, it will be shown as ”Not used”.
This function is used during the summer to cool the building night-time using cool outdoor air, thereby reducing the need for cooling during the day and saving energy.
Support control is used for adjusting the room temperature outside of the normal running time. If there is a heating or cooling demand in the ro om, the unit will start and the temperature will be adjusted.
The fire function determines the settings for the fire dampers and the unit’s runn ing mode when a f i re alarm is activated.
Frost protection is normally always used in water heating syst ems. The cooling recovery function starts the heat exchanger in order to return cooling fr om the extract air when the extract air is colder than the outdoor air and cooling is required.
An analogue i nput can be configured for an external setpoint device e.g. TG-R4/PT1000.

Temperature
Here you can view all actual and setpo int values for temperature control. The menu is visible to all users, regardless of log on level. However, to make changes you need at least Operator authority.
Only menus for activated functions will be shown.
Setpoint Supply air temperature control
Here, actual and setpoint values are shown, as well as the outdoor temperature if a outdoor sensor has been configured. This is a read-only menu. No s ettings can be made here.
Submenu: Setpoint.
Setpoint Outdoor temperature compensated Supply air control
Here, actual and setpoint values are shown, as well as the outdoor temperature if a outdoor sensor has been configured. This is a read-only menu. No s ettings can be made here.
Submenus: Setpoint
In control modes Supply air control/Room control and Supply air control/Extract air control , the setpoint relationship is used when supply air control is active.
Use the eight breakpoints to generate a setpoint / outdoor temperature relationship.
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 1°C for every 5 °C lowering of the outdoor temperature. So the setp oint at –23°C would be 25°C + 0.6x 1.0°C = 25.6°C.
Setpoint Cascaded room temperature control
In control mode Supply air control/Room control, the setpoint is used when cascade connected room control is active.
Submenu for setting the min and max limitation temperatures for the supply air.
If two room sensors have been configured you will also get this menu. The controller uses the average temperature of the two sensors.

This function operates according to the assumption that one may accept a slig htly higher indoor temperature when it is warm outside and vice versa, providing an exc ellent opportunity for conserving energy.
Support control heating/Support control cooling
Support control is normally used when room temperature control or extract air control has been configured, to prevent a too large offset in temperature when the unit is “Off”.
“Support control Heating” or “Support control Cooling” will run if support control is configured, the running mode is "Off" (timer control OFF and not in extended running) and if conditions call for support control.
Minimum run time is settable 0 to 720 minutes (FS= 20 minutes).

Exchanger de-icing
This menu is shown if excha nger de-icing has been configured. If the temperature at the de-icing sensor drops below the setpoint value, the de-icing function is started. It is stopped when the temperature has risen above the setpoint plus the set differential.
Heat exchanger efficiency monitoring
The function calculates the heat exchanger temperature efficiency in % when the output signal to the exchanger is hi gher than 5 % and the outdoor temperature is lower than 10°C. The function requires an ex tract air sensor , an exhaust air sensor and an outdoor sensor or an efficiency sensor, extract air sensor and outdoor sensor.
When the cont rol signal is lower than 5% or the outdoor temperature is hi gher than 10°C the display will show 0%.
Recirculation
The first of the three below menus can be found under Configuration in the controller. The fourth menu is located under Temperature.
Recirculation is a function for mixing the air in the room using the supply air fan. The functi on can be used even when there is no heating or cooling demand. When using recirculation control, the extract air fan stops and a recirculation damper opens which allows the air to circulate through the unit.
It is selectable whether or not the extract air fan should run during recirculation.

During recirculation, offset SAF makes it possible to add to the supply air fan an offset to the setpoint during normal operation. If pressure control has been configured, the offset is set in Pa. If flow control has been configured, it is set in m3/h. If manual control has been configured, the offset is set in %.
If you have selected the Offset function, which is a deviation from the regular supply air setpoint, you will instead be given the opt ion to change this offset value here.

General
Corrigo has a year-base clock function. This means that a week-schedule with holiday periods for a full year can be set. The clock has an automatic summertime/wintertime change-over.
Individual schedules for each week-day plus a separate holiday setting. Up to 24 individual holiday periods can be configured. A holiday period can be anything from one day up to 365 days. Holiday schedules take precedence over other schedules.
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.
Up to 5 digital outputs can be used as timer c ontrolled outputs. Each with individual week ­schedules with two activation periods per day. These outputs can be used to control lighting, door locks etc. Only outputs which have been configured will be s hown. Timer output 5 can be used to control a recirculation function.

Timer Normal speed
There are 8 separate setting menus, one for each weekday and one extra for holidays. Holiday schedules take precedence over other schedules.
For 24 hour running, set a period to 0:00 – 24:00.
To inactivate a period, set the ti me to 00:00 – 00:00. If both periods of a day are set to 0:00 – 0:00, the unit will not run at normal speed that day.
If you want to run the unit from one day to another, e.g. from Mon 22:00 to Tue 09:00, the desired running time for the various days must be entered individually.
First Mon 22:00 – 24:00....
...then Tue 00:00 – 09:00.
Timer reduced speed
These settings will be ignored if single speed fans are configured.
Should periods for normal speed and periods for reduced speed overlap, normal speed takes precedence.
Structure and function is otherwise identical with Timer Normal speed.
Extended running
Digital inputs can be used to force the unit to start although the t imer says the r unning mode should be “Off”.
For 2-speed fans and pressure/flow controlled fans, inputs for normal speed and reduced speed can normally be used.
The unit will run for the set time. If the running time is set to 0 the unit will only run as long as the digital input is closed.
Extra timer outputs 1 … 5
Up to 5 digital outputs can be used as timer c ontrolled outputs. Only outputs which have been configured will be shown. Each with individual week-schedules with two activation periods per day.
Each timer output has 8 separate setting menus, one for each weekday and one extra for holidays. Holiday schedules take precedence over other schedules.
If the function Recirculation has been configured, Timer output 5 can be used for controlling start/stop of the Recirculation function.

Holidays
Up to 24 separate holiday periods for a full year can be set.
A holiday period can be any number of consecutive days from one and upwards. The dates are in the format: MM-DD.
When the current date falls within a holiday period, the scheduler will use the settings for the weekday “Holiday”.
Access rights
There are four different access levels, Normal level which has the lowest access and does not require logging on, Operator level, Service level and Admin level whic h has the highest access. The choice of access level determines which menus are shown, as well as which parameters can be changed in the displayed menus.
The basic level only permits changes in Running mode and gives read-only access to a limited number of menus.
Operator level gives access to all menus except Configuration. Service level gives access to all menus except the submenus Con figuration/In - a nd Outputs
and Configuration/System. Admin level gives full read/write access to all settings and parameters in all menus.
Repeatedly press down-arrow when the start-up display is shown until the arrow-marker to the left of the text-list points to Access rights. Press RIGHT.
Log on
In this menu it is possible to log on to an y access level by entering the appropriate 4-digit code. The log on menu will also be displayed should you try to gain access to a menu or try to do an operation requiring higher autho rity than you have.
Press the OK button and a cursor marker will appear at the first digit position. Repeated ly press the UP button until the corre c t digit is displayed. Press the RIGHT button to move to the next position. Repeat the procedure until all four digits are displayed. Then press OK to confirm. After a short while the text on the line: Present level will change to display the ne w log on level. Press the LEFT button to leave t he menu.

Other functions
Alarm handling
If an alarm condition occurs, the red alarm LED on the front panel of units with display or the alarm LED on a connected display unit 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 button­top.
If there are multiple alarms, this is indicated by up / down arrow symbols at the ri ght-hand edge o f the display.
Use the UP and DOWN buttons to access the other alarms.
At the left end of the bottom display line the ala rm status is shown. For active, unacknowledged alarms the space is blank. Alarms that have been reset will be indicated by the text Acknowledged. Still active or blocked alarms are indicated by the text 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.

Language
If RIGHT is pressed three times when the start menu is shown, a menu is displayed in which the language can be changed.
The different language files are stored in the application memory and are downloaded to the work memory. If a Corrigo has been reloaded with a program revision newer than the factory revision using E tool
©
, the controller will not allow language fi le s to be downloaded from the application memory. This is because there is a risk that the language files are not compatible with the new revision. Therefore, you are limited to the two languages you have downloaded using E tool

Indication LEDs
Status indication can be found in the upp e r left corner of the controller. For controller s with display, the alarm indication and change mode LEDs are located in the keypad area.
Status indication
Changing the battery
Corrigo has an internal battery to ensure the operation of the memory and real-time cloc k in the event of a power failure. When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery has become too weak and needs to be changed. Nonetheless, due to a backup capacitor, the controller will function at least 10 minutes without power supply. Since changing the battery requires knowledge of proper ESD protection, as well as dismantling and opening of the unit, this should be handled by skilled service personnel.
