Page 5: Chapter 2 About Corrigo E
Corrigo E for heating is a complete new range of programmable controllers for control of building heating systems. Corrigo E series for heating comprises three model sizes: 8, 15 or 28 in-/outputs. Available with or without front panel display and buttons. For units without front panel display and buttons a separate, cable-connected terminal E-DSP with display and buttons is available.

Page 8: Chapter 3 Installation And Wiring
Chapter 3 Installation and wiring 3.1 Installation Corrigo E can be mounted in a DIN-standard casing (minimum 9 modules), on a DIN-rail in a cabinet or, using a suitable front-mounting kit, in a cabinet door or other control panel. Ambient temperature: 0…50°C. Ambient humidity.
Page 9 Analogue outputs Analogue outputs must refer to the A-gnd terminal placed in the AO terminal block. All analogue outputs can be individually set to any one of the following signals: 0…10 V DC 2…10 V DC 10…0 V DC 10…2 V DC If the Corrigo E and the actuators connected to it share the same transformer it is essential that the same transformer-pole is used as reference for all the equipment.

Page 15: Chapter 4 Commissioning
Chapter 4 Commissioning General Before the Corrigo can be used it must be configured, inputs and outputs must be assigned and all relevant parameters must be set. All commissioning can be done using the Corrigo front panel display and buttons or using the display unit E-DSP.
Page 16 Functional description Start by reading the chapter 5. Functional description below. Some functions are essential to the working of the unit and must be included. Others are more of the nature of optional extras which can be excluded. At the end of each function description there is a table of the necessary inputs and outputs to implement the function.
Page 17: Chapter 5 Functional Description
Chapter 5 Functional description 5.1 Heating systems 5.1.0 General Corrigo E can be configured for 1 to 3 heating systems (radiator groups), HS1, HS2 and HS3. 5.1.1 Controllers The heating system controllers are PI-controllers with settable P-band and I-time. 5.1.2 Control curves The controllers have individual outdoor temperature / supply temperature control curves.
Page 18 5.1.7 Building inertia and boost The building inertia is settable to one of three levels: None, Medium, High. The set inertia dictates the influence of outdoor temperature. With no inertia, the outdoor temperature is used directly, with medium inertia a one-hour average is used and with high inertia a 12-hour average is used.
Page 19 5.2.4 Pump control (HW1 only) Corrigo E has a digital output signal that can be used to control the hot-water circulation pump in HW1. The pump will run according to the settings of the night set-back schedule, running during normal temperature periods and standing still during periods with reduced temperature. 5.2.5 Periodic overheating Once daily, at 02:00 am the temperature set-point can be increased to 62°C to prevent growth of Legionella bacteria.
Page 20 5.6.2 Alarms Pulse error If no pulses are detected within a settable time an alarm is activated. Setting the time to 0 inhibits the alarm function. High usage If the daily usage is higher than a settable value an alarm is activated. Leakage control If the lowest hourly usage during the previous day is higher than a settable value an alarm is activated.
Page 21: Alarm Priorities
5.9 Timer channel outputs Up to 5 digital outputs can be used as timer controlled outputs. These can be used for controlling, for example, door locks, lighting, laundry-room equipment etc. Each timer has its own scheduler with two activation periods for each day of the week and a year- based holiday calendar.
Page 22: Chapter 6 Display, Leds And Buttons
Chapter 6 Display, LEDs and buttons This section is applicable to Corrigo E units with display and buttons but also to the hand terminal E-DSP which can be connected to Corrigo E units without display and buttons. 6.1 Display The display has 4 rows of 20 characters. It has background illumination.
Page 23 6.4 Navigating the menus The start display, the display normally shown, is at the root of the menu tree. Pressing DOWN will move you through the menu choices at this, the lowest level. UP will move you back through the choices. To enter a higher menu level, use UP or DOWN to place the display marker opposite the menu you wish to access and press RIGHT .
Page 24: Chapter 7 Access Rights
Chapter 7 Access rights There are 3 different log on levels, System level which has the highest authority, Operator level and the basic “no-log on” level. System level gives full read / write access to all settings and parameters in all menus. Operator level gives read-only access to all settings and parameters and write access to all settings and parameters in all menus except Configuration.

8.1.2 Digital inputs DI Digital input 1 NO/NC: NO Signal: HS1-PumpA Status: Off To simplify adaptation to external functions, all digital inputs can be configured to be either normally open, NO, or normally closed, NC. The inputs are as standard normally open, i. e. if the input is closed, the function connected to the input in Corrigo is activated.

Page 29 8.3 Return water temperature Individual maximum and minimum return water temperatures can be set for the heating systems. Should the water temperature go outside the set limits the supply water temperature will be adjusted to correct. The adjustment will be the temperature offset multiplied by the set limiting factor. 8.3.1 Maximum temperature Max.
Page 30 8.5 Twin pump / Single pump Each heating system can be configured for either a single pump or twin pumps. When twin pumps are configured, the pumps are alternated weekly on Tuesdays at 10:00 am. On activation of the pump alarm for the active pump the Corrigo will automatically switch to the other pump.
Page 31 Actuator run time HS1: 255 sec HS2: 255 sec HS3: 255 sec Actuator run time HW1: 80 sec HW2: 80 sec 8.9 Valve exercising The valves can be exercised once daily. Default time is 3:00 pm but can be set to any time. The actuators will be forced to either endpoint for the set actuator running time.

Page 36 If Corrigo is to be wired to a network for Modbus communication, a special code must be purchased from Regin. Entering the code unlocks the unit so the addresses can be changed. The code is unique for each Corrigo and is serial-number dependent.
Page 37 Via a connected GSM modem, Corrigo can send an alarm message to up to 3 different recipients. To use this function, you first have to purchase a lock-up code from Regin. When there is an alarm, Corrigo sends an alarm message to the first number on the list. The message consists of an alarm text, the unit name (the same text that is shown in the first row of the start display) and the time when the alarm occurred.
