The low draft Pressure Switch is a differential
pressure switch that senses the negative pressure
(draft) in the firebox. If the draft becomes too low for
proper combustion, the switch opens, interrupting
power to the feed motor and the igniter. This switch is
connected into the AC (high voltage) wires.
The hopper lid Position Switch is located in the
rear corner of the hopper opening. If the hopper lid
is not closed properly, the switch opens, interrupting
power to the feed motor and igniter circuits. This is to
protect against reaching into the feed mechanism while
in operation.

The Control board/ESP combination is responsible
for all high limit safety control. There are 2 high limits,
one normal operation high limit and one backup high
limit. The control has an automatic diagnostic circuit
that continuously monitors the ESP and Room Sensor
for faults. If a fault should occur, the control sends a
status alert and at the same time the unit goes down
to minimum feed/minimum burn as a safety condition.
