  • Page 32 Rotating exchanger Control Rotational speed is controlled by the analogue signal ”Y2 Heat exchanger” or by two digital outputs “Exchanger 3-pos. actuator, increase” and “Exchanger, 3-pos. actuator, decrease”. A rotation sentinel can be connected to the digital input ”Rotation sentinel Exchanger”. An alarm is generated if this input is activated at the same time as the analogue output signal is higher than 1.0V.

  • Page 39: Extra Control Circuit

    A special analogue output signal, Y1 Heating/Y3 Cooling, is used for Change-over control. Switching between heating and cooling can be done in two ways. A digital Change-over input signal is normally used. Open contact will give heating control and closed contact cooling control. If the input has not been configured, change-over is handled by the internal controller signal.

  • Page 40: Fan Control

    Digital humidity signal A digital output signal, Dehumidification/Humidification, can be used for on/off control of humidifier/dehumidifier. The output signal has an activation value and a deactivation value which are connected to the humidity controller output. The signal is activated when the humidity controller output rises above the set activation value and is deactivated when the humidity controller output drops below the set deactivation value.
  • Page 41 5.4.1 Pressure control Frequency control pressure When running pressure control, two analogue output signals are used for supply and extract air respectively. The signals control the fan speeds via frequency converters, thereby maintaining constant pressure. A digital activation signal is normally used for each fan (Start SAF frequency converter and Start EAF frequency converter), for sending a start signal to the frequency converters.
  • Page 42 Frequency control external control signal Two 0…10 V input signals are used for direct control of frequency controlled fans. The signal is received from for example a VAV unit. The signal controls the fans 0…100% (0…10V on the analogue output). Pressure transmitters are not used in this control mode. Frequency control SAF with EAF slave The rotational speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct.
  • Page 43 You can choose to activate the function 1. Always, 2. Only when the running mode is On, 3. Only when the running mode is Off. When the function is activated and combined with pressure controlled fans and the CO /VOC-value rises above control value 1 the fans will start at low speed, if they are not already running.

  • Page 44: Pump Control

    If demand controlled ventilation is activated in combination with mixing dampers, and the CO value rises above the setpoint value, the dampers will let in more fresh air. The function is controlled by a PI-controller. See section 5.1.3 Heat exchanger types. The function has a settable minimum running time.

  • Page 45: Damper Control

    5.6 Damper control 5.6.1 Close-off dampers The fresh air and exhaust air ducts close-off dampers can be controlled by digital outputs or be hard- wired to the supply air fan relays for normal and reduced speed in such a fashion that the damper is open when the supply air fan is running.

    The fire alarm input can be configured as normally closed or normally open. Inputs and outputs Fresh air damper control Exhaust air damper control Fire dampers Fire alarm Fire damper end switch monitoring 5.7 Extended running and External stop The digital inputs for extended running can be used to force the unit to start although the timer says the running mode should be “Off”.

  • Page 51: Navigating The Menus

    7.4 Navigating the menus From revision 2.3, significant changes have been made to the Corrigo menu system. The purpose is to make the menu system more structured and user-friendly. The choice of access level/user access determines which menus are shown. The start display, the display normally shown, is at the root of the menu tree.
  • Page 52 If there are further settable values displayed the cursor will automatically move to the next one. To pass a value without changing it, press RIGHT. To abort a change and return to the initial setting, press and hold the C-button until the cursor disappears.

  • Page 53: Chapter 8 Access Rights

    Chapter 8 Access rights There are four different access levels, System level which has the highest access, Service level, Operator level and the basic “no-log on” level. The choice of access level determines which menus are shown, as well as which parameters can be changed in the displayed menus. System level gives full read / write access to all settings and parameters in all menus.

    Expansion unit In order to connect more I/Os to the Corrigo, port two is set as expansion unit (only Corrigo E controllers can be connected). It is possible to connect two units which gives a maximum of 28*3 = 84 inputs/outputs. The expansion controllers must have the addresses 241:1 and 241:2 respectively (ELA:PLA).

The same time applies to both fans. Retardation time 1/1-1/2speed: 10 sec 16.27.3 Heating at start-up and high speed blocking At outdoor temperatures below the set value, the heating output will be forced to 100% before start- Two speed fans and pressure controlled fans can be blocked from using high speed at outdoor temperatures lower than the set value.
  • Page 92 For example P-band for the supply air controller is set to 33K. The HCOut is set so that cooling gets 0…30% = 30%, the exchanger gets 32…50% = 18% and the heater gets 54…100% = 46%. The individual P- bands will then be: Chiller: 30% of 33°C = 10°C Exchanger: 18% of 33°C = 6°C Heating: 46% of 33°C = 15°C...

The split is always even 50/50 which means that each part of the split will have half the part of the P-band assigned to the output.

  • Page 95 16.28.4 Address Corrigo E uses the addresses below when connecting to Corrigo E tool, and when multiple controllers are connected in an EXO network. E tool normally uses the addresses below, so if an address is changed, the new address must also be entered in E tool. If several Corrigo are connected in a network, all the units must have the same ELA address, but each unit must have a unique PLA address.

    Chapter 17 Expansion model There are eight different 2-port Corrigo models with 15/28 inputs/outputs, with or without display, and with or without TCP/IP port. For a list of the different models, see page 8 (Corrigo E model overview). 17.1 Port 1 On a 2-port Corrigo, port 1 is used for connection to E tool and possibly a SCADA system.

    The different language files are stored in the application memory and are downloaded to the work memory. If a Corrigo via E tool has been reloaded with a newer program revision than the factory revision, the controller will not allow language files to be downloaded from the application memory.
