NOTE: Only for GFX4 with CTs present and outputs OUT1...OUT4 with slow cycle time
(1...200sec) all HEAT or all COOL.
In case of GFXTERMO4, the 4 CTs must be connected to outputs OUT1...OUT4.

HETEROGENEOUS power control
Available only for Mod. 80 kW 57A full scale
This function matches that of a thermal cutout that disconnects the load based on instantaneous input. The load is
disconnected based on a preset priority.
Zone 1 has priority: in case of overload, zone 4 is disconnected, followed by zone 3, etc.
The maximum total controllable current in four zones for the 80 kW model is 160A.
The maximum current in a single zone is 57A.
Example: you can control three 50A loads and one 10A load without limits. With four 50A loads, if there is simultaneity,
the load connected to zone 4 is disconnected.
