Controls Flexibility for Pool Ventilation

This unit was designed to provide fresh air ventilation for a modest-sized pool in Wisconsin. It was built for indoor installation and has a DX coil with controls by others. XeteX, however, provided straightforward analog controls for the blowers and the exchanger. This allowed XeteX to implement specialized energy recovery functions such as Frost Control, Economizer, and Summer Changeover, but it left the customer with the flexibility to use a controls contractor to configure the rest of the equipment on-site. The unit was therefore able to meet the specification without providing any superfluous components. And with an energy recovery rate as high as 82.6% under winter design conditions, it offers tremendous value to the customer.
