Customer is wanting to convert their 100 ton York YCUZ880 from 2 large recips to 4 scrolls and from R-22 to 407C
is it possible to fool the processor on the oil pressure transducer? We can put a thermistor on the oil temp. Any other help would be appreciated.

Welcome to the forum.

Processor will look for positive differential oil pressure within 30 seconds of start up, i think trip point is below 0.7bar. Is this a packaged unit or remote condenser only?

Are the existing compressors fubar'd or is there another reason for wanting to fit scrolls? If the compressors are J series there used to be a conversion kit for the heads (wave springs etc)
