Corrigo user guide Ventilation application Copyright AB Regin, Sweden, 2016
About this user guide This user guide covers all the models in the Corrigo series used with the ventilation application. The document only covers functions which are available to users with Operator access and lower. Revision F, 2016 Software revision: 3.X More information More information about Corrigo can be found in: • Manual Corrigo Ventilation – Complete manual for configuration and maintenance of Corrigo with ventilation application, available in Swedish, English, German and French.
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.
• Extra control sequences Y4 and Y5 (in addition to Y1, Y2 and Y3) for free integration into the controller output. • Heat exchanger (liquid connected, plate or rotating) or mixing dampers. • Heating coil: Water with or without frost protection or electric with high temperature limit switch. • Cooling: Water or DX cooling in up to 3 steps. • Circulation pumps for heating, exchanger and cooling. • Recirculation dampers. • 1- or 2-speed supply air and extract air fans.
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.
Display, buttons and LEDs This section is applicable to Corrigo units with display and buttons but also to the hand terminal E3-DSP. For third generation controllers, it is also possible to connect an external display to units that are equipped with a display and buttons. E3-DSP Display Vent sys controller 2016-11-20 13:30 System: Normal run Sp: 18.0 Act: 18.2°C The display has 4 rows of 20 characters. It has background illumination.
The menu system Navigating the menus The choice of access level/user access determines which menus are shown. Regulator vent. sys 2016-11-20 13:30 System: Running Sp: 18.0 Act: 18.2°C 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©.
There are sometimes further submenus linked to a menu or menu item. This is indicated 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.
Running time SAF: 14.6 EAF: 14.4 Shows the accumulated running times for the fans. h h Selected functions Control function Supply air control Fan control Pressure In these menus, you can see how some of the most important functions have been configured. Changes cannot be made. Heating: Water Exchanger: Plate exc Cooling: Water Heater, exchanger and cooling type. If one of the functions is not used, it will be shown as ”Not used”.
Alarm events 24 Nov 14:32 B Malfunction supply air fan Acknowledged Alarm log, containing the 40 latest alarm events. The most recent event is listed first. The alarm log can only be used for viewing the alarm history. Alarms are handled in a special area, see the section Alarm handling. Inputs/Outputs AI DI UI AO DO These menus show the current values for all configured inputs and outputs. These are read-only menus. No changes can be made here.
Temperature Here you can view all actual and setpoint 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 Outd temp:18.4°C Supply air temp Act: 19.8°C Setp Setp: 20.0°C 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.
Setpoint Cascaded room temperature control Room temp1 Actual: 22.0°C Setpoint: 21.5°C In control mode Supply air control/Room control, the setpoint is used when cascade connected room control is active. If cascade control max/min supply setp Max: 30.0°C Min: 12.0°C Submenu for setting the min and max limitation temperatures for the supply air. Room temp2 Actual: 21.8°C If two room sensors have been configured you will also get this menu.
Outdoor -20.0°C -15.0°C -10.0°C comp setp = 25.0°C = 24.0°C = 23.0°C This function operates according to the assumption that one may accept a slightly higher indoor temperature when it is warm outside and vice versa, providing an excellent opportunity for conserving energy. Outdoor comp setp -5.0°C = 23.0°C 0.0°C = 22.0°C 5.0°C = 20.0°C Outdoor comp setp 10.0°C = 19.0°C 20.0°C = 18.0°C If cascade control max/min supply setp Max: 30.0°C Min: 12.
Exchanger de-icing Deicing exchanger Actual: 11.2°C Setp: -3.0°C Hysteresis: 1.0°C This menu is shown if exchanger 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.
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 option to change this offset value here.
Air control This menu is only shown if frequency controlled fans have been configured. Depending on the choice of fan control, different combinations of the menus below will be shown. Pressure control SAF (there are also corresponding menus for EAF) Pressure control SAF Actual: 480 Pa Setp: 490 Pa Here, Actual and Setpoint values are displayed. This is a read-only menu. No settings can be made here.
