Abstract
An HVAC controller for an equipment enclosure or machine room employs ambient air exchange and compressor driven cooling appliances for maintaining an operating temperature of a telecommunications machine room within acceptable levels. Coordinated engagement of the ambient air exchange and a plurality of lead/lag cooling appliances provides staged engagement of the cooling appliances to correspond to a cooling demand. Designation of lead and lag cooling appliances is alternated according to a designation interval to avoid disproportionate use of individual cooling appliances for promoting longevity. Multiple cooling appliances alternate the lead/lag designation to equalize equipment wear, and alternation of the lead/lag designation follows an normal operational satisfaction of the cooling demand, to minimize a frequency of equipment engagement (power up) cycles which contribute to wear.
