The

 low draft Pressure Switch

 is a differential pressure 

switch that senses the pressure between the firebox and the 

room. If the negative pressure in the firebox becomes too 

low  for  proper  combustion,  the  switch  opens,  interrupting 

power to the feed motor and the igniter.  If the switch "opens" 

during a rest period, the control will not try to feed or ignite. If 

the circuit opens during a feed or ignition cycle, the indicator 

lights will remain "on".

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.
