In this mode, the control box is ready to work by contact type normally open (NO) or normally closed (NC), located at the digital
input J11. When the status of this input changes, the fan goes to low speed with a set value in % of maximum speed.
Logic:
• NO (normally open): The fan pass to low speed when contact is closed.
