If I have two Multiplus 2 units and connect them in split phase it is my understanding that one must be the master and the other the slave.
1) Is this true, in order for split phase to operate must the two units have a master slave relationship?
2) If the two units are connected master/slave can I still program the K1 relay and the alarm relay of the slave to work differently than the master?
3) If units are connected master and slave can I at least program the k1 relay and alarm relay of the slave unit to mirror (copy exactly, do the same as) the relays of the master?
