The following points are listed in relation to the pres-
sure switch function and operation.
• The pressure switch has no control on the water level in
the tub. The water level is time fill controlled.
• Contacts 1 to 2 provide a signal to the controller to
terminate the drain mode after pump out.
• In the satisfied position, contacts 1 to 3 are open. No wire
is connected to terminal 3 of the pressure switch. The
controller senses the open circuit and advances the
program.
• The actual "head" of water present from the bottom of the
load collector to the "Y" connection of the pressure switch
hoses actuates the pressure switch diaphragm.
results in a satisfied condition (i.e. contacts 1 to 3 reading
an open circuit).
