8.2 Selection of Charging Function
The G-50A system provides the following 3 methods to calculate the charge by measuring instruments. For
the objective models that can be charged by each method, please refer to Table 4-3.
(1) Manual input of electric power consumption
This method is only applicable to the charging of electric power consumed by air conditioners.
Without using a watt-hour meter, this method calculates electric power consumption in a ratio of each
tenant (charge block) by using the daily operation amount and the set capacity of the air conditioner.
Utilizing the electric power apportioned charging calculation tool of the integrated software, the reading
value of the watt-hour meter of the outdoor and indoor units is input manually to calculate the air
conditioning charge.
As the standard charge can not be set by this method, it should be added by the user.
(2) Watt-hour meter pulse counting (Apportioning method)
This method is only applicable to the charging of electric power consumed by air conditioners.
By apportioning the electric power measured by the watt-hour meter connected to the air conditioner
and the daily operation of the air conditioner, the electric power consumption per tenant (charge block)
can be calculated by this method.
(3) Measuring instrument pulse counting (Direct reading method)
This charging method covers the Free Plan LOSSNAY for which the above apportioning method is not
available, the air conditioning electric power of A-control models, the general electric power of lamps
and plug sockets, and the charge of city water.
In such cases, you are kindly requested to install a measuring instrument for each charging block for
charging in a unit of measuring instruments.
(4) Electric power count by PC direct connect (RS-485WHM)
This charging method is only applicable to the charging of electric power consumed by air conditioners.
By apportioning the electric power measured by the watt-hour meter connected to the air conditioner
and the daily operation of the air conditioner, the electric power consumption per tenant (charge block)
can be calculated by this method.
