1.2 Design Precautions
1.2.1 Calculation Condition
(1) Remote controller group
Also in the indoor unit (sub-unit) with remote controller group, set the group address for correct electric energy
distributing.
(The group 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 group 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 included
It is necessary to connect the watthour meter to the power supply line of the indoor unit and input its pulse to iTM.
In this case, “included power of Fan” has to be set to “Yes” in the PPD setup tool.
