SEQUENCE OF OPERATIONS

Mechanical Timer
1. To turn the unit on, depress the red on/off rocker switch.
• 115 VAC is sent to normally open drain valve closing it.
• 115 VAC is sent to the Timed/Manual switches for the
cabinets.
• 115 VAC is sent to L1 and L2 of the water level board.
2. With the water level board energized and no water in the boiler
• 115 VAC is sent from the IND terminal to the low water
indicator light on the console.
• 115 VAC is sent from the WF terminal to the fill solenoid
after a 5-second delay.
• The fill solenoid opens and the boiler fills.
• The water fills to the secondary low water cutoff probe in the
boiler, shorting it to ground
• 115 VAC is removed from the IND terminal and the low
water indicator light is de-energized.
• 115 VAC is sent from the HTR terminal through the
normally closed contact of the high-pressure switch to the
normally open contacts of the amber reset switch,
• 115 VAC is sent through the normally closed R1 contacts
to energize the amber light on the reset switch.
• If the low water cut off probe is not grounded for 20
seconds, 115 VAC is removed from HTR and sent back to
IND energizing the low water light.
3. When the momentary amber switch is depressed 115 VAC is sent
to the R1 relay closing it.
• The normally closed R1 contacts open de-energizing the
amber light.
• The relay latches through the normally closed contacts of R1
• If either the high-pressure switch (set at 15 PSI) or the
low probe circuit on the water level board opens, then the
latch circuit opens.
• When the water level or pressure returns to a safe
condition the amber light will energize and the process
may begin again.
4. The R1 relay contacts close sending 115 VAC through the
normally closed operating pressure switch to the primary coil of
the 24 VAC transformer.
