The SL4-BE integrates operation data from each indoor unit and watt-hour meter’s pulses and exports this information to

Calculating data files. A USB memory can be used to transfer the data files to a computer where proportional distribution

calculations can be performed for energy used using the included software.

Ki = Ki + K

= : Amount of operation for air-conditioner per minute

Amount of operation is calculated with the following 3 methods. (Set the calculation method on the air-conditioner definition

screen of SC-SL4-BE.)

Amount of operation when the value converted to the rated expansion valve aperture of air-conditioner is E:

• MULTI 1 (Refrigerant ﬂow rate): Add a conversion value that takes into consideration the ﬂow rate of refrigerant ﬂowing through the

Thermostat ON indoor unit. ( Ej)

(Ej: Conversion value of indoor unit expansion valve aperture per minute)

• MULTI 2 (Thermostat ON/OFF): Convert the time when refrigerant is ﬂowing through the indoor unit and add. (Thermostat ON time

× E)

• SINGLE (Compressor ON/OFF): Calculates the operation time of the outdoor units (outdoor unit operation time × E).

• ON/OFF (Operation time): Convert the state when the remote control is turned ON and add the value. (Operation time × E)

(E: Conversion value of indoor unit capacity per minute)

* Set the same watt hour meter system at the same type.

* If it is set at MULTI 1 or MULTI 2, indoor units in the fan mode are excluded from the proportional distribution.

If you need to include the indoor units under the fan mode in the proportional distribution, set it to ON/OFF.

* When the air-conditioning is not used in a day (Ex. Holiday), and thus there is no operating indoor unit to divide in proportion, the

portion of standby power does not match the value on the meter. It is necessary to re-calculate the accounting data using the spreadsheet

software.

• A simplified software to edit the accounting data is included in the accessories. Regarding the operating method, refer to the manual

attached to it.

• The accounting data can be output via the attached USB memory.

• (Calculating data files can be downloaded over a LAN connection.

Super Link Adapter Usage Precautions

A Super Link adapter (SC-ADNA) is required when connecting to an inverter packaged air-conditioner. Please set to SINGLE

(Compressor ON/OFF) or ON/OFF (Operation time). However, when a single Super Link adapter is connected to multiple

indoor units that use different coolant systems, please set to ON/OFF.

When “SINGLE” is selected, calculations are performed based on Compressor ON/OFF information. Therefore, when a single

Super Link adapter is connected to multiple indoor units that use different coolant systems, operation data may not be accurate.

Furthermore, when controlling multiple indoor units using a Super Link adapter, please set to “ON/OFF.” Otherwise, calculation

processing is not performed correctly.
