The ADC150 is a Modulating Fan and Damper Control used with gas fireplaces where it monitors and maintains a constant draft in a chimney. It is used with model RS fans.
It monitors the draft in a chimney system via a connection to a pressure transducer (XTP) attached to the chimney and maintains the draft by modulating the fan speed. It provides a 10-120V AC power to single phase fans and 0-10V DC control signal to control 3-phase fans via a variable frequency drive. The control has an integrated safety system that assures the heating appliance(s) is shut down in case of insufficient draft after 15-180 seconds (user adjustable). The ADC150 has an integrated damper relay that works with ENERVEX MFD (Mechanical Fireplace Damper) to automatically open the damper prior to fan initialization and close the damper after the appliance shuts down. End-switches in the damper actuator wired to the ADC150 ensure the damper must be fully open prior to allowing the appliance to operate. The control also features a post purge function (3 min) to evacuate the chimney system of residual flue gases after the appliance shuts down.
