Fig. 17 shows this relay actual size. Take care with
the following step, as the terminal posts can easily
be broken. Lift the clip from the rear terminal post of
terminal 1 and place it on the rear post of terminal 3.
With the front-mounted toggle switch in the "AUTO”
position, the plant will respond immediately when the
automatic demand control senses a load. The bilge
blower will run.
The Control-O-Matic shcfuld not need attention, but if
it does not function properly, see the Trouble-Shooting
section for repair procedures.
