1.2.1 Rate Calculation
(1) Remote controller group control 
Also in the indoor unit (sub-unit) with remote controller group control, set the centralized address for correct electric
energy distributing.
(The centralized address for sub-unit can be set in the site set mode “30” of the remote controller.
However, after setting with “30”, if set with “00”, the sub-unit address will be deleted.)
An imperfection in case collective distribution is done with main-unit running state without setting of centralized
address at sub-unit
Even if the remote controller group control is done, each indoor unit has different thermostat state depending on its
installation place.
Therefore, the distribution result will differ depending on the decision which indoor unit is to be as main unit.
(2) In Case power consumption of indoor unit to be distributed 
In distributing the power consumption of the indoor unit, it is necessary to connect the integrating watthour meter to the
power system of the indoor unit and input its pulse output to intelligent Manager.
If such a wiring is connected, in making equipment setting in test run, set at “To make distribution calculation for indoor
fan” with intelligent Manager calculation conditions.
