2.1.5 Advanced Cascade Control MCO 102
The MCO 102 option supports a maximum of eight pumps and is able to alternate the lead pump with two adjustable frequency drive relays per pump.
This reduces the need for external auxiliary switches as well as the cost of installation.
When the MCO 102 (C-option) is used, the number of relays can be increased to a total of 13 by adding the MCB 105 (B option).
