Connection
Connect a shielded, 2 core, twisted pair control cable from
the C225/C325F2 to the 2 and 3 terminals in the Fujitsu FCU.
Polarity of this cable is critical — see Figure (m) below if polarity
is connected incorrectly simply reverse the polarity and cycle
the power to the A/C unit and the Myzone controller. Do not use
the terminal 1 (12V) when connecting to a Myzone system.
