12.3 Basic Sequence of Operation

All sequence of operation information for units controlled
with ALC controls is available in the ALC Sequence of
Operation documents that can be requested from your
manufacturer's Addison representative for each specific job.
• Sequence of operation information specifically for the
operation of the electric heater modules within the
above referenced document.
For sequence of operation information for units controlled
with field-supplied DDC controls (whether factory-
mounted or field-mounted), consult the DDC controls
manufacturer and/or installer.

12.4 Accessory Controls Options

Accessory controls options include, but are not limited to:
• Carbon Dioxide Detector: This option provides a
room-mounted carbon dioxide detector for initiating
additional outdoor ventilation.
• Clogged Filter Indicator: This section provides a
differential pressure switch and status indication.
• Exhaust Fan Interlock: This option provides an
interlock between an exhaust fan and the unit.
• Firestat: This option de-energizes the unit when
the stat, mounted in the return air section, senses
return air above 135 °F (57.2 °C). The firestat must be
manually reset.
• Freezestat: This option shuts down the unit when
the discharge temperature falls below the
controller's setpoint.
• Service Receptacle: This option provides a 115V
service receptacle with 15A breaker. It is mounted in a
2" x 4" (51cm x 10.2cm) enclosure. It can be field-wired
or factory-wired (outdoor condensing section only).
• Smoke Detector: This option provides an ionization
type supply air smoke detector which shuts off the
unit if smoke is detected.
