Regin Corrigo Controller Manual: Features, Configuration, and Installation

1. Introduction to Corrigo

The Corrigo series controllers are used for ventilation control and can function as stand-alone units or be integrated into SCADA systems. Two hardware platforms exist: the 24V Corrigo Ardo and the 230V Corrigo Vido. The controllers offer various I/O configurations. The manual details display options, the PC-based Application tool for configuration and commissioning, and the internal web interface.

1.1 Display

The display features 4 rows of 20 characters with background illumination, activated by button presses. An external display can also be connected for monitoring and control.

1.2 Application Tool and Configuration

The free, PC-based Application tool from Regin's website is used for configuring and commissioning the controller. Configurations can be made offline and uploaded to the controller via a communication cable. Predefined configurations are available for download.

1.3 Internal Web Interface

When connected to a network, the controller provides an internal web interface accessible via a browser for monitoring and changing setpoints, as well as configuration.

1.4 Comparison Between User Interfaces

This section compares the capabilities of text displays, the ED-T43L-V touch screen, the web interface, and the Application tool for tasks ranging from viewing actual values to complete system configuration.

2. Information for the End User

2.1 Display, LEDs, and Buttons

Details the physical interfaces of the Corrigo Vido (5 buttons) and Corrigo Ardo (7 buttons). It describes the display, LED indicators for status and alarms, and the functions of each button for navigation, data entry, and alarm management.

2.2 Navigating the Menus

Explains how to navigate through the controller's menus using the navigation buttons ([Up Arrow], [Down Arrow], [Left Arrow], [Right Arrow]) and the [OK] button to select options or enter submenus. Menu visibility depends on the user's access level.

2.3 Changing Values

Provides a step-by-step guide on how to edit existing values or enter new ones. This involves entering change mode using the [OK] button, using navigation buttons to position the cursor, modifying digits with [C]/[Navigation button] or [Up Arrow]/[Down Arrow], and confirming changes with [OK]. Changes can be undone using [C]/[Navigation button].

2.4 Logging On and Off

The controller supports four access levels: Guest, Operator, Service, and Admin, each with different permissions. The process for logging on (entering a password), logging off, and changing passwords for different levels is detailed. Default passwords and automatic logoff settings are also provided.

2.5 Menu Structure and Features

Outlines the main menu structure accessible to end-users, including Ventilation, Additional function, Time settings, Alarm events, Inputs/Outputs, Configuration, and Access rights. It describes submenus for Ventilation (e.g., Actual/Setpoint, Temperature control, Fan control) and Time settings (e.g., Time schedule, Holiday schedule, Time/Date).

2.6 Alarm Events and Alarm Handling

Explains how alarms are logged and prioritized (A, B, C). Users can inspect alarms, acknowledge them, block them (requiring a higher access level), and unblock them. The alarm list shows active and acknowledged alarms.

2.7 Internal Web Interface

The web interface offers an overview of system status, allows login with different user levels, and provides customizable homescreens (Simple or Technical view). Users can change timer settings, adjust setpoints, and utilize a signal analyzer (trend) to monitor historical data for analog and digital signals.

3. Information for the Specialist - Function Descriptions

This section details the advanced functions and operational parameters of the Corrigo controllers, intended for technical personnel.

3.1 Function Overview

The Corrigo supports a wide range of functions for building automation, including various temperature control modes, fan control (speed, pressure, flow, demand-controlled), humidity control, pump control, damper control (including fire/smoke dampers), pretreatment, filter monitoring, and more. These functions can be configured based on the physical I/O capabilities of the controller.

3.2 Temperature Control

Details multiple temperature control modes such as Supply air, Supply air outdoor compensated, Room cascade, and Extract air cascade. These modes manage heating and cooling sequences (A-J) to maintain desired temperatures, often utilizing PI control loops. Configuration involves selecting control types, sensors, and adjusting parameters like setpoints, neutral zones, and PID values via the Application Tool.

3.3 Temperature Sequences

Explains the use of sequences (A-J) for specific heating or cooling functions. Types include Heater (Water, Electric, DX), Exchanger (Rotating, Plate, Liquid), and Cooler (Water, DX). Functions like freeze protection, defrosting, and control logic for these sequences are described, with configuration managed through the Application Tool.

3.4 Fan Control

Covers various fan control methods, including pressure control, flow control, manual settings, and external control. It details configurations for supply and extract air fans, including slave control, demand-controlled ventilation based on CO2 levels, step control, and the use of frequency converters. Fan compensation curves and SFP (Specific Fan Power) calculation are also explained.

3.5 Humidity Control

Describes humidity control capabilities, including humidification, dehumidification, and combined modes. It details the use of humidity sensors, PI controllers, and output signals for controlling humidifiers or dehumidifiers, with options for duct sensor limitation.

3.6 Damper Control

Covers the control of close-off dampers for outdoor and exhaust air, and fire/smoke dampers. It explains their operation modes, activation during fire alarms, and testing procedures, including end-position switch feedback.

3.7 Pump Control

Details the control logic for circulation pumps in heating, exchanger, and cooling circuits. It includes settings for pump exercise, stop delays, and run indications.

3.8 Pretreatment

Explains the control of dampers and pumps for preheating or precooling outdoor air via underground intake channels, including temperature-based activation and blocking logic.

3.9 Filter Monitoring

Describes how filter monitoring can be activated, allowing for air flow dependency in pressure drop alarms and setting alarm thresholds.

3.10 Extended Operation and External Stop

Covers manual overrides for unit operation (extended running) and the function of external stop signals, which take priority over other control modes.

3.11 Time-switch Outputs

Details the configuration of up to four digital time-switch outputs, each with individual weekly schedules, for controlling external devices like lighting or door locks.

3.12 Extra Controller

Describes an independent temperature control circuit that can be configured for heating or cooling, suitable for controlling separate zones, with options for manual control and freeze protection.
