This option allows the management of up to eight different tariffs
with reference temperature control. The measurement is split into
different registers.

Function for stopping the energy calculation when the temperature
difference is too low, ΔT LFCO adjustable ΔT = 0-2.99 K.
One-sided or two-sided, hysteresis 0 – 10 %, action of the output
signal is selectable.
