CenCon
6
GENERAL OVERVIEW
The Engineered Air CenCon controller is the primary operational component for the majority of custom
manufactured Engineered Air HVAC equipment. Expansion modules (-XM) may be added to extend the
operational capabilities to gas fired heating, cooling, humidification and energy recovery systems.

Notice:
There is approximately a 1 minute delay before operation can commence on initial power up. The CenCon has
to load parameters and configurations prior to operation. The time varies depending on the complexity of the
equipment it is controlling.

1
Digital input connection to the CenCon or any of the expansion modules cannot use Mosfet solid
state switches. Input switching must be mechanical.
2
If using 4-20mA, add a 500Ω resistor across the input terminals.
3
Analog inputs will trigger 10Vdc ‘high’ if using 24Vac input and a series Diode (1N400x).
