If the MIQ96 has relay output/outputs (see section 16.5 page 34), relay output 1 is corresponding to counter 3 (import kWh) and relay output 2 is corresponding to counter 4 (import kvarh).
  • Page 20: Maximum Demands (Md)

    The MIQ96 displays the present or “dynamic” maximum demand (value below “PRESENT MD”). The MIQ96 also stores the maximum demand value since last reset and its corresponding time stamp, visible either from the MIQ96 display or remote communications link (value below “MD at DD.MM HH:MM”).
