5.1 Configuration of the Corrigo

The configuration of the Corrigo is made in Application tool, a free PC-based software available on www.regincontrols.com

The controller doesn't need to be connected to the computer while configuring. All settings are made in the tool and then uploaded to the controller.

An infinite number of configurations can be stored in the computer memory for later use.

A communication cable is required in order to upload the configuration to the controller. The controller must also be powered up and the application selected in order for it to be configured.

5.1.1 Predefined configurations for Corrigo

There are predefined configurations available for easy configuration. They can be selected in the internal text display, in the web interface or can be downloaded as atf-files on Regin's webpage. The atf-files can be used in Application tool for further offline modification and adaption.

The predefined configurations are a part of Regin's Ready-Steady-Go concept which makes it much easier and faster to configure the controller.

Predefined configurations in internal text display

Use the internal text display in the Corrigo to select a predefined configuration.

Description More information

The speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct. The extract air fan is controlled by the supply air flow, in order to achieve a balanced ventilation. A pressure transmitter which is placed in the supply air fan cone (SAF flow) gives a measured value of the present supply air flow. A corresponding pressure transmitter is placed in the extract air fan cone and gives a measured value of the extract air flow.

The supply air flow is the setpoint used for control of the extract air fan. A scaling factor can be added if the extract air fan does not have the same characteristics as the supply air fan.

Function description:

chapter Supply air pressure with extract air flow slave

The speed of the extract air fan is controlled by a pressure transmitter which is placed in the extract air duct. The supply air fan has no pressure transmitter. Instead, the supply air fan output is made to follow the extract air fan control signal. A scaling factor can be added if the supply air fan characteristics are not the same as the characteristics of the extract air fan (only pressure control of the extract air fan is possible using this function).

Function description:

Extract air fan pressure with supply air flow slave

The speed of the extract air fan is controlled by a pressure transmitter which is placed in the extract air duct. The supply air fan is controlled by the extract air duct flow in order to achieve a balanced ventilation. A pressure transmitter placed in the extract air fan cone (EAF flow) provides a measurement of the current extract air flow. A corresponding pressure transmitter is placed in the supply air fan cone, providing a measurement of the supply air flow.

The supply air fan is controlled using the extract air flow as a setpoint. A scaling factor can be added if the supply air fan does not have the same characteristics as the extract air fan.

Function description:

Fan levels

A frequency controlled fan is the only type of fan that works with the Corrigo. The fan can be set to Low,

Normal or High speed. The selection of the fan speed defines which IOs and time channels will be active in the application.

The fans will always start directly with the desired speed.

There are four different fan speed levels to choose from in Application tool:

✓ Normal

✓ Low - Normal

✓ Normal - High

✓ Low - Normal- High

Variable speed control uses an analogue output per fan or Modbus communication for controlling a frequency converter.

For more information about frequency converters, see

Appendix F Frequency converters and EC controllers for heat exchangers

110 (196) Corrigo manual, Rev. D

Information for the specialist - Configuration

The fans are normally controlled by the timer channels for slow, normal and high speed but can also be started via digital input or communication.

The extract air fan and the supply air fan have individual start and stop delays which are normally set so that the extract air fan is started before the supply air fan. If there are not enough digital outputs for individual control, both fans will have to be started using the signal for the supply air fan, and the delay will be created using an external time relay.

Fan compensation

When running pressure/flow control or manual frequency control, it is also possible to for the pressure/flow or output to be temperature compensated.

This compensation can be made depending on any analogue input such as supply air, extract air, room, outdoor temperature, humidity, CO

2 and so on. There are three equal compensation functions available.

It is possible to compensate either one or both of the fans at the same time and it is possible to set which fan should then be compensated, the supply fan or the extract air fan.

Support control

Support control is normally used when room temperature control or extract air control has been configured.

When extract air control is configured a room sensor must be installed.

Support control can also be configured to start only with the supply air fan. In this mode, the extract air fan is not active. This requires a digital output to be configured, which controls the recirculation damper to open completely so the supply air fan can circulate the air to and from the room.

CO

control

In applications with varying occupancy the fan speeds or mixing dampers can be controlled by the air quality as measured by a CO

2 sensor.

With the CO

2 function it’s possible to start and stop the fans, compensate the fan speed and in combination with mixing damper let in more outdoor air depending on the CO

2 value. This can be configured with the

2 control settings, see

Table 5-12 CO

2 control settings .

Free cooling

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.

Free cooling requires an outdoor sensor or an intake temperature sensor and either a room sensor or an extract air sensor. If both an outdoor sensor and an intake sensor is configured it uses the outdoor sensor for the function.

Free cooling is only activated when all the start conditions below are fulfilled.

✓ Less than four days have passed since the unit was last in running mode.

✓ The outdoor temperature during the previous running period exceeded a set limit (22°C).

✓ It is between 00:00 and 07:00:00 in the day (settable).

✓ The timer outputs for Normal speed, Extended running, Normal and External switch are Off .

✓ A timer channel will be On sometime during the next 24 hours.

If an intake sensor is used and/or an extract air sensor is selected and ALL the start conditions are fulfilled, free cooling is activated and will run for 3 minutes (settable) to ensure that the temperature measurement when using an extract air sensor reflects the corresponding room temperature and that the intake temperature sensor senses the outdoor temperature even if it is placed in the fresh air inlet duct. If an outdoor sensor and a room sensor is selected, the unit will not start free cooling as long as all the temperatures are not within the start and stop temperature intervals.

Recirculation

Recirculation is a function for distributing the air in the room using the supply air fan. The function can be used even when there is no heating or cooling demand. When using recirculation control, the extract air fan stops (but can also be set to run) and a recirculation damper opens which allows the air to circulate through the unit.

Recirculation is activated either via a digital input signal or by connecting it to Extra time channel 4 (

Application tool - Time control). If timer output for Low/Normal/High speed is activated during recirculation via Extra time channel 4 , Low/Normal/High speed gets priority. If timer output for Low/Normal/

High speed is activated during recirculation activated by a digital input, recirculation gets priority.

Either a digital output (Recirculation damper) or an analogue output sequence (A toJ) can be used as an on/ off output signal.

Recirculation control can be configured as either air circulation (temperature control inactive) or air circulation with temperature control. (Only heating, only cooling or both heating and cooling). Recirculation control has its own setpoint. However, the other settings are the same as for normal operation, i. e. if normal operation has been configured as room control, room control will also be used during recirculation.

Pretreatment

Control of dampers and pump for preheated or pre-cooled outdoor air via an underground intake channel.

The digital output Pretreatment is set to preheating when the unit is started and the outdoor temperature is below the set heating start limit or to precooling when the outdoor temperature is above the set cooling start limit. If the outdoor temperature exceeds the set heating start limit by more than 1°C, preheating will be aborted, as well as if the outdoor temperature falls below the cooling start limit by 1°C.

Extra controller

An extra controller can be used as an independent temperature control circuit for control of for example separate zones. The circuit can be configured to heating or cooling. It has an analog input signal for temperature sensors and an analogue output signal (0…10 V). There is also a digital output signal which is activated when the analogue output signal is above 1 V and deactivated when the analogue signal is below

0.1 V. The circuit can be configured to be active all the time or to be active only when the unit is running or when defrosting.

Fire / Smoke

Fire dampers are normally configured to open on fire alarm but can be configured to be normally open instead. It is possible to configure which speed the fans should have when in fire mode – however, this is not possible when the fire function has been set to Running via normal start/stop conditions . Setting the fan speed to -1 % will deactivate the fan speed selection. Read more about the fire/smoke function in

Humidity control

Humidity control can be configured as Humidification, Dehumidification or both Humidification and

Dehumidification.

Two humidity sensors can be connected, a room sensor for control and an optional duct sensor for maximum limiting. The limit sensor can be omitted.

The humidity control is handled by a PI-controller.

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

Filter monitoring

Turn on filter monitoring to monitor the flow through the filter. Analog filter guards may be made air flow dependent. This means that a higher pressure drop is permitted across a filter at a higher air flow. For this purpose, X and Y coordinates are used to set the linear function that should be followed at a pressure drop alarm.

Extended operation

The digital inputs for extended running can be used to force the unit to start in reduced, normal or high speed although the timer says the running mode should be Off . This digital input has always higher priority than running via time schedule.

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.

External stop

The signal External switch will stop the unit, even if the timer or one of the signals Extended Operation, Low ,

Extended Operation, Normal or Extended Operation, High says it should stay in running mode.

Extra fan motor control

External control of an external fan motor can be configured. The fan is started via either a digital input, time channel 4 or when the unit is started.

Time channel 4

A digital output activates the fan motor. A digital input is available for run time indication/motor protection.

Damper

The outdoor air and exhaust air ducts close-off dampers can be controlled by digital outputs or be hardwired to the supply air fan relays for normal, reduced and high speed in such a fashion that the damper is open when the supply air fan is running. When using pressure controlled fans the digital activation signal is activated as soon as the fan has start conditions. This signal can be used to open the close-off damper.

Damper location to choose from:

✓ Outdoor

✓ Outdoor + Exhaust

✓ Exhaust

Automatic restart after power on

This function makes it possible to block automatic restart of the unit at power-up. At power-up, the B-alarm

Restart blocked after power on is generated. Once this alarm has been acknowledged, the unit will start. See more about alarms in

Starting order heating/cooling

Setting of the order of the sequences is made in Configuration ► Functions ► Sequence heating/cooling.

It is possible to define a specific start order for the different sequences for heating and cooling demand.

The selectable number, 1…10, defines the start order of the sequences. If two sequences have the same start order they will work in parallel.

Start order heating shows only sequences which can work as a heating sequence, such as:

✓ Heater

✓ Exchanger

✓ Damper

✓ Fan setpoint compensation

Start order cooling shows only sequences which can work as a cooling sequence, such as:

✓ Cooler

✓ Exchanger

✓ Damper

✓ Fan setpoint compensation

The following picture (

5-9 ) shows the default settings of the configured sequences A=Heater, B=Exchanger

and C=Cooler, where the Exchanger (SEQ. B) starts first in heating mode followed by the Heater (SEQ. A).

In cooling mode, the Exchanger (SEQ. B) starts first followed by the Cooler (SEQ. C).

Sequence settings

These settings are used the define the start of the sequences when the unit starts. There are two different modes to start the unit:

✓ Normal start up

✓ Warm (Heat) start up

Normal start up:

The sequence control starts at 100% for the heating sequence which is selected at the parameter At start up begin temperature control at 100% in . The default setting is Heating 1 , which means it starts at 100% for heating sequence 1 which is the exchanger in the default configuration.

Corrigo manual, Rev. D 119 (196)

Information for the specialist - Configuration

Warm start up:

If the outdoor temperature is lower than the settable limit Warm start up if outdoor temperature < (°C) the unit will start in the warm start mode. A second sequence will start at 100% in this mode if the unit starts. The default setting is Heating 2 , which means it starts at 100% for the heating sequence 2 which is the heater in the default configuration

5.11 Time control

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 an automatic summertime/wintertime change-over.

It has individual schedules for each weekday 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.

This menu displays time, date and weekday, and it permits the setting of time and date.

Time is shown in 24 hour format.

Date is shown in the format YY:MM:DD.

Figure 5-10 Time channels

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

Up to 4 digital outputs can be used as timer controlled outputs . Each with individual week-schedules with two activation periods per day. These outputs can be used to control lighting, door locks etc.( Configuration ►

5.12.2 Alarm configuration

The alarm configuration menu permits configuration of the priority for all alarms. A complete alarm list with default settings and actions, can be found in

Appendix D Alarm list . It contains all the default alarm texts and

priorities.

Priority

Alarms can be given different priority levels A-alarm , B-alarm and C-alarm or Not active . Digital outputs can be bound to act as alarm outputs for A-alarms or B/C-alarms or both A- and B/C-alarms. The digital outputs can be inverted, so that an inoperative alarm gives a high output and vice versa. A- and B- alarms must be acknowledged to reset. C- alarms automatically reset as soon as there is no longer a cause for alarm.

The alarm priority that is shown in the display in the event of an alarm can only be changed using

Application tool.

Alarm text

The alarm text that is shown in the display in the event of an alarm can be changed using Application tool or the web interface.

Stop function

Each alarm offers the possibility to choose whether an activated alarm should stop the controller or not. The controller can also be set to run at reduced speed during alarms. The latter option can only be configured using Application tool. Automatic restart will take place when the alarm has been acknowledged.

For some alarm types such as electric heating high temperature limit and water heating frost protection it would be dangerous to not stop the unit on alarm. Therefore, for such alarm types, the program will always reset the stop function to Active even if the operator should choose Inactive .

Corrigo manual, Rev. D 153 (196)

Information for the specialist - Configuration

Unfortunately it is not possible to remove the display text concerning the stop function for these alarm types. This is because the available program space demands that all alarms are treated in the same way in the display.
