• Check chapter Electrical wiring for wiring details.
• This manual provides basic information for installing and wiring CHL-MBS-01.
• RCME-AH chillers use a different H-Link protocol compared with AG(1) and AG2(B) chillers, so they cannot be connected on to the
same H-Link line when using the same CHL-MBS-01.
