POWER ON LOAD
Power on the load in each zone is read in variable Ld.P
Impedance in each zone is read in variable Ld.I.
If zone 1 has a 3-phase load, variable Ld.P.t shows power and Ld.I.t total impedance.
Note that for loads such as IR lamps, impedance can vary greatly based on the power transferred to the load.
