•• VRV Systems • Network Solution369 Design Precautions9 - 1 Rate calculation9 - 1 - 1 Remote controller group controlAlso 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.9 - 1 - 2 In case power consumption of indoor unit to be distributedIn distributing the power consumption of the indoor unit, it is necessary to connect the integrating watthour meter to the power system of the indoorunit 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 Managercalculation conditions.9 - 1 - 3 Calculation of electric power (Crankcase heater/PC Board power consumption) at stopping1. In the case of calculation for crank case heater and PC Board when not in operation.The electric power consumed by crank case heater of the outdoor unit is divided by the capacity of each indoor unit.N.B. The calculation also includes the indoor units which are not in operation. (eg.vacant)2. In the case of not calculating for crank case heater and PC Board when not in operation.It is possible to exclude the power consumed by crank case heater and PC Board.Therefore the power won’t be added to each indoor unit.3124Bldg.-usemulti-typeIntegrating watthour meter (For SkyAir)Integrating watthour meter (For building-use multi-type outdoor unit)Integrating watthour meter (For building-use multi-type indoor unit)Group1 Group2SkyAirDIII-NETRemote controllergroup controlSkyAiradapterDTA102A2G1234GG5678Di-1 Di-2 Di-3 DIII-11 2 3 4 5 6 F1 F2
