If the system requirement is to have the internal pack
controller for 3 compressors plus by-pass valve connected,
there is the need to specify FC 103 with the extra relay
card (MCB 105) mounted inside the frequency converter.
The bypass valve must be programmed to operate from
one of the extra relay outputs on the MCB 105 board.
This is needed because the standard relay outputs in the
FC 103 are used to control the compressors in the pack.
