Chapter 1 About the manual This manual covers all the models in the Corrigo E series used with the ventilation application. This revision covers program revisions from 3.2. More information More information about Corrigo E can be found in: •...
Page 7: Chapter 2 About Corrigo E
Corrigo E series comprises three model sizes: 8, 15 or 28 in-/outputs. In each model of Corrigo E generation 2, all applications are loaded in a separate memory area. The models have article number E...-S (where S stands for Second generation). From version 3.0, there are models with two communication ports.

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.
Page 15 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. Failure to do so will prevent the equipment from functioning as intended and may also lead to damages.

Chapter 5 Functional description 5.1 Temperature control General Corrigo E has a choice of the following control modes: Supply air control Outdoor temperature compensated supply air control Cascaded room temperature control Cascade connected extract air temperature control Outdoor temperature dependent switching between supply air control and room...
Page 30 The supply air temperature is kept at the setpoint value by controlling the output signals for "Heating Y1", "Exchanger Y2", "Cooling Y3", "Extra sequence Y4" and “Extra sequence Y5”. A single PI control loop is used. Functional description Manual Corrigo E Ventilation, revision Q...
Page 31 The room temperature can be compensated when the outdoor temperature increases. One can, for instance, imagine accepting a slightly higher room temperature if it is warm outside or, conversely, a slightly lower temperature if it is chilly. This function is included to conserve energy. Manual Corrigo E Ventilation, revision Q Functional description...
Page 32 The unit is restarted when the alarm has been acknowledged and the temperature for the frost protection sensor has risen above “Alarm limit frost” + “P-Band”. Frost protection control is available on Y1 Heating, Y4 Extra sequence or on both Y1 and Y4. Functional description Manual Corrigo E Ventilation, revision Q...
