Two-stage modulating Copeland scrolls work with a 24v DC solenoid in the scroll set. That solenoid energizes and de-energizes, which either fully or partially loads the compressor. Load matching is ideal for efficiency and comfort, meaning that the two-stage Copeland scrolls perform well in those areas. Unsurprisingly, the fully-loaded option.

Unsurprisingly, the fully-loaded option.Put the new compressor in, do a full write up on it, logging pressures, temperatures, amperages. Once you do this, the answer should be pretty obvious. If it isn't, post here and we'll try to help you. 12-14-2010, 01:29 AM #3 Phase Loss Professional Member Join Date Feb 2008 Location California Posts 2,091 Post LikesAdvanced Scroll Temperature Protection. This feature protects your compressor from excessively high discharge temperatures. ASTP eliminates the need for a discharge line thermostat through our unique internal protection system. ASTP provides superior reliability, reduced warranty rates, and more value to the customer.range 10 to 100% capacity modulation of Copeland Scroll™ compressors for high, medium, and low ... compressor is not pumping.I have had a large number of failures with Copeland scroll compressor in split systems. I have been using the enviro-safe freon replacement. These have been 2.5, 3, 3.2 and 3.5 ton units.The scroll sets separate at the instant of compressor shutdown. This allows the scroll set internal pressures to equalize on compressor stops. In addition to this, the scroll sets are not engaged at the instant of starting.Scroll sets engage only after few milliseconds of startup. This allows easier startup of ZB scroll compressors.Due.

Some compressor manufacturers, such as Copeland, use a different factor. They divide the MCC by 1.44.Advanced Scroll Temperature Protection (ASTP) Operation Motor protector resets, compressor restarts Bi-metal disk resets before motor protector Cycle will continue until cause of overheat is fixed Motor protector opens Compressor turns off, cools Compressor "unloads" but continues to run "Balanced pressure" operation Motor heat builds ...How the Copeland Digital Scroll Compressor works as used in the Samsung DVM Re: Copeland Scroll not pumping If the scroll has a sticker of ASTP indicating internal by pass then there is a possibility at low pressures only motor runs with internal bypass . I have experienced the same in bulk milk cooler whereas the milk quantity was less than 25% of tank capacity and LP switch setting was too low .For example, Copeland AE4-1303 states: “Copeland Scroll compressors incorporate internal low vacuum protection and will stop pumping (unload) when the pressure ratio exceeds approximately 10:1. There is an audible increase in sound when the scrolls start unloading.”. This is to prevent the compressor from pulling down into a vacuum.Two-stage modulating Copeland scrolls work with a 24v DC solenoid in the scroll set.
