Alarm Stages
Flashes 1 - if damperprove does not close 90 seconds after auxin, go into alarm for 30 seconds, followed by a full
retry
Flashes 2 - if initial pdsprove does not close 180 seconds after damperprove, go into alarm for 30 seconds,
followed by a full retry
Flashes 3 - if pds loses proof for 15 seconds after initial pdsprove, auxouts de-energize, stay in alarm until
pdsprove returns and auxout will re-energize
Flashes 4 - if at any point after auxout proves the damperprove is removed, the board immedialy goes into alarm
for 30 seconds, followed by a full retry
Flashes 5 - *must have sw3 on* if pds is proved prior to auxin, board will go into alarm and no further states can be
achieved until proof is removed
Start 1. A call for heat from the appliance energizes the ADC100 inputs at terminals 9 and 10.
Sequence 2. If a damper is connected, it begins to open. Once open, the damper prove contact closes (Terminals 16 and 17).
3. The ADC100 begins to ramp up the fan.
4. The Proven Draft Switch closes when adequate draft is achieved and ADC100 adjusts fan to speed setting on
the potentiometer.
5. The ADC100 control releases the appliance for operation by closing dry contact between terminals 22 and 23
(and terminals 29 and 30).
Operating Manual Mode:
Sequence 1. Fan runs at a constant speed and can be adjusted during normal operation using the potentiometer.
2. If the Proven Draft Switch opens, a 15 second timing cycle starts.
3. If the Proven Draft Switch has not been made within 15 seconds, the auxiliary out contact opens and an
alarm condition exists.
4. If the Proven Draft Switch closes, the control automatically resumes normal operation at set speed.
