Sequence of Operation
The Pearl Economizer Controller provides automated control of
HVAC Economizers and associated equipment. The controller has
built-in logic to:
−
Deliver cool outdoor air to reduce the need for
mechanical cooling.
−
Provide necessary ventilation in commercial
buildings.
−
Supply Demand-Controlled ventilation based on
measured CO2 levels in the conditioned space.
−
Control a variable speed fan based on types of
demand.
The sequence of operation for each of these functions works
independently except for the overlap of damper position
requested by each function. The overlapping requirements are
arbitrated to provide the required outdoor air for each function.
