4.11.2 Function
Ultra 3PH Full Module has to be combined with UltraCella controls (P/
Ns WB000S% or WB000D%). Module has inside high power actuators
to handle directly three-phase loads of the condensing and evaporator
units, but logic and regulation algorithms are inside UltraCella.
In the table below details of where probes and loads can be connected.
Nota:
• Although three-phase loads have to be physically connected to Ultra
3PH Full module, UltraCella maintains its standard confi guration of
relays.
