E281W-3 Corrigo Ardo - configurable controllers for ventilation and heating.

This product is discontinued

Corrigo comes preloaded with applications for control of ventilation and heating. The Corrigo controllers are BTL listed, click here to go to the BACnet International website where you'll find PICS documents and more information.

Corrigo ventilation

Corrigo running a ventilation application is intended for control of air handling units with temperature control, 1- or 2-speed operation or, alternatively, pressure or air flow control of supply air fan and extract air fan, humidity control as well as other common functions in ventilation.

Corrigo heating

Corrigo running a heating application is intended for control of heating substations in buildings. The controller supports control of up to 3 heating circuits and 2 DHW circuits. Corrigo heating also has built-in boiler control for a total of 4 boilers. It can also controll a cooling circuit with dew-point control.
