External fan connection

I have a Multiplus 24/5ooo/120. I would like to connect an external fan to draw air into the cabinet where it is fitted when the temperature goes up (fitted in a mobile home). Is there a connection inside the unit that will switch on 24V to operate the fan when it gets hot?

No there is no connection for that.
But you can setup one of the relays of the Multi to switch on if the internal fan is switched on.

Wire (+) through a fuse to COM of the relay and from NO you can go to the fan. The (-) is connected directly to the fan.
