STAGED COMPRESSORS
On a call for cooling, the compressors will stage on from 1 to 6. The CenCon cooling programming does not
allow for random start, only sequential. Inter-stage and anti-cycle timing is built into the CenCon program and
is not adjustable.
On the initial call for cooling only, the inter-stage time of the first 2 stages is decreased.
AMBIENT CONDENSER FANS
The CenCon may incorporate up to 2 ambient temperature based condenser fan (or ambient based
compressors) enable contacts.
LOW AMBIENT LOCKOUT
Mechanical cooling is disabled below the design low ambient lockout setpoint, typically set at 50°F (10°C), and
58°F (14°C) for makeup air appliances.
