Performex-1 CONTROLLER : OPERATION & FUNCTIONS The Zamil Packaged units are provided with technologically advanced new Performex Controller Microprocessor Based Electronic Control Board, incorporating the following benefits and features: - COMPLETE UNIT CONTROL: Provides complete unit control for heating and cooling application whether single stage or two stage utilizing the input from sensor that measure temperatures during unit operation.
7. LEAD/LAG OPERATION: Whenever a compressor needs to be on, the controller will turn on the compressor with the shorter accumulated run time provided its 3 minutes minimum off time has lapsed. Otherwise the other compressor will on first. Similarly, the compressor with the longer accumulated run time will be the first one to be cut off. This is to load the compressors evenly over long run period.
MAINTENANCE INSTRUCTIONS AIRFLOW ADJUSTMENT (Applicable for PS075 - PS360 only) The airflow could be adjusted by adjusting pulleys of blower motor or belt tension with proper mounting and alignment of the pulleys: • Refer to fan performance tables in the catalog for selecting applicable airflow, RPM and brake horse power at specified static pressure.
