1. Product Information
1.1 Function
Use The ENERVEX ADC100 Draft Control is a fan speed and appliance control used to control draft for a
 gasappliancesuchasareplace,stoveorfurnace.Itmaybeinterlockedwiththeapplianceandisforuse
in systems where modulation is not required. It controls the speed of a fan to maintain proper draft and
pressure in a chimney system. The ADC100 is for use with ENERVEX model RS or GSV fans and is
a component in the residential EcoDamper
.
.
Function The ADC100 control comes with the PDS1.
The PDS is a required safety function used to ensure a negative pressure is maintained in the chimney. It
also prevents appliance operation during an electrical or mechanical failure in the system.
The ADC100 can operate the chimney fan in manual or automatic mode. Manual mode allows
the user to adjust the speed of the fan at any time using the potentiometer on the board. In Automatic
Mode, the ADC100 will ignore the potentiometer and ramp the fan up until the PDS closes. If the PDS
opens, the control will ramp up the fan until there is enough draft to re-close the switch.
The ADC100 can be interlocked with up to two appliances. Connections are made at the Auxiliary In and
Auxiliary Out terminals. A 24VDC out connection is available. When an appliance is interlocked to the
control, a post-purge function becomes available. The post purge keeps the fan running for a set time after
 thelastapplianceshutsdowntoevacuateanyremaininguegases.ThepostpurgetimeontheADC100
is adjustable from 0-3 minutes via a potentiometer on the control board.
The damper relay allows a damper actuator to be interlocked directly to the control. The control ensures
that the damper is open before releasing the appliance for operation. If at any point the control has sensed
total failure, the ADC100 will go into an alarm for 30 seconds and will attempt a retry. In the event of a
mechanical or electrical failure, the damper fails to the open position.
Construction The housing is NEMA 1 rated ABS plastic.
