Beginning March 2003, an enhanced Flash Memory Card will be supplied in all new production YK chillers. These
cards are backward compatible to all previous YK chillers and are available from the Baltimore Parts Distribution
Center as replacement parts. The enhancements are outlined below.
The versions and part numbers are applied as follows:
• NEMA 1-4 chillers C.MLM.01.08.105A (p/n 031-01797-001)
• CE chillers C.MLM.01.08.206A (p/n 031-01797-002)
Chiller Style/Compressor Setpoint
In previous Flash Memory Card version, this setpoint key (located on OPERATIONS Screen), was labeled “CHILL-
ER MOD”. For clarity, this setpoint key is now labeled “CHILLER STYLE/COMPRESSOR” (English only).
The functionality of this setpoint has changed slightly as follows:
The previous choice of “Style F chiller/G, H compr” is now “Style F chiller/G, H5-8 compr”. The previous choice
of “Style F chiller/J compr” is now “Style F chiller/J, H3 compr”.
