Introduction1.0 INTRODUCTION1.1 System DescriptionsDeluxe System/3 environmental control systems are available in several configurations. Each configurationcan operate with either Advanced Microprocessor Controls (AM), or Advanced MicroprocessorControls with Graphics (AG). A brief description of each, including operational differences, can befound below. Check model numbers to see what is supplied with your unit.1.1.1 Compressorized Two-Step SystemsThese systems may be air, water, or glycol cooled, depending on the heat rejection method selected.CoolingTwo stages of mechanical refrigeration are available.HeatingThree stages of electric reheat are standard; steam/hot water, hot gas (on water and glycol cooled systems)are optional.HumidificationInfrared is standard. Steam grid and steam generating humidification are optional.DehumidificationThese systems utilize the lag compressor.1.1.2 Compressorized Four-Step SystemsThe four-stage systems have all the features of a compressorized, two-stage system plus cylinderunloaders on one head of each compressor. This permits the compressors to operate at a reduced leveland increases energy efficiency during low-load conditions. The system responds to an increasingroom load with either a two-step or a four-step process of increasing the unit's cooling.CoolingThese systems have four stages of mechanical refrigeration:a. Lead compressor at reduced capacityb. Lead and lag compressors at reduced capacityc. Lead compressor at full capacity; lag compressor at reduced capacityd. Lead and lag compressors at full capacityHeatingThree stages of electric reheat are standard; hot water/steam are optional.HumidificationInfrared is standard; steam grid and steam generating humidification are optional.Dehumidification.These systems utilize the lag compressor.1
