(7)Notes on charge system

•If there is a group that is not set in the charge block, the electric power amount for that group will not be included in the air-conditioning charge. If there are groups which require charging to be divided, set those groups as operation blocks or charge blocks to accomplish this.

•The air conditioning charge can be calculated by block units or by power meter units. Note that even when OA processing unit, LOSSNAY, A control unit or K control unit are included in the block setting, they are not included in the air conditioning charge of the block unit.

•The function for Charge calculation (Without WHM connection) is only applicable to the indoor unit. It does not apply to OA processing unit, LOSSNAY, A control unit, and K control unit, etc.

•Some older M-NET control indoor units are not compatible with the charge function.

•When the system is changed or the air conditioner is extended, which may require address changes, the charge calculation may be affected in some cases.

Executing such changes or extensions are recommended after gaining approval from the building owner(s).

(8)Charging (Billing) restrictions

The air conditioning cost calculation method use by this integrated software TG -2000A is the Mitsubishi proprietary general electric power apportioning method. Thus, it is not calculated using watt hour meters installed at the power supply to each unit. Additionally, it cannot be employed in applications demanding calculations based on watt hour meters installed at each unit. Thus when using this unit, we recommend a separate contract be established between the building owner and the tenant that specifies “air conditioning fees will be collected based on proport ional usage (including special considerations for downtime).”

(9)Function description

•The function/specifications may partially change and improvements may be made without any notice.
