Fellow Sailors, I have a 1997 Hunter 376. On my electric panel on the A.C. side the last three switches are AC Fore , AC Aft, & RELAY. I believe I have only ONE AC unit. Therefore, are AC Aft & RELAY functional?? What does RELAY service?? Many Thanx, " Murph "

Relay function
The pump was controlled by a relay box, which activated the pump when either of the 2 airco units were turned on
With only 1 airco, the pump is run directly from the airco, and no relay is required
With installations where there were 2 airco units, they shared the same water pump.
