Exhaust fans
The supplied air shall be able to smoothly leave the building at ceiling level (as
high as possible).
When mechanical exhaust fans are used, these can be powered and controlled by
the IntrCooll® with a 0-10V modulating control signal.
The contractor shall provide/install a 2-wire cable between the IntrCooll® and the
exhaust fan and a separate power supply cable to a local mains power source.
IntrCooll® PCB connector to control the exhaust fan: J7.
It is advised to install fans with capacity equal to the amount of air supplied by
the IntrCooll®. The IntrCooll® software has the ability to slightly reduce the airflow
(field setting) to prevent negative pressure inside the building.
Note
Make sure the exhaust fans can be controlled with a 0 V - 10 V signal
