8.14.2 Division mode (Step 1)
Follow these steps to set the reference data and Division
Mode for outdoor and indoor units in the charge system.
Select the Division Mode or proportional division
refer-
ence data.
[Procedure]
1) Select the Division Mode.
Click the option button of the desired Division Mode.
2) Select [OK] button.
When done making selections, click the [OK] button.
* If the [Cancel] button is clicked, the settings are interrupted
and the screen returns to the initial window.
a) Proportional division reference data
The power consumption of the outdoor units is the sum of the Operating Power and Standby Power
(for the crankcase heater).
The Operating Power for the outdoor unit is divided proportionally in accordance with the reference
operation data of the indoor unit.
Reference data 1 : Capacity save(electric amount used) ... (Default)
Reference data 2 : Thermo on time (usage time of compressor)
Reference data 3: FAN operation time (usage time)
b) Division mode for outdoor unit
Choose the mode of the Standby Power for the outdoor unit from the following:
Mode 1 : Includes the Standby Power in the apportioned data.
Mode 2 : Apportions the Standby Power separately from the Operating Power, according to the
capacity ratio of the indoor units. (Default)
Mode 3 : Includes the Operating Power in the apportioned data but does not include the Standby
Power.
c) Division mode for indoor unit
Select the division mode for indoor unit electric amount used (primarily FAN).
Do not : When the power consumption of the indoor units is not apportioned, or the watthour
meter is not connected to the indoor units.
Do : Use the formula (cumulative indoor unit usage × power input) when dividing. (Default)
Note:
• The proportionally divided power charge function (Without WHM connection) can only be selected
as the “Proportional division reference data”.
• The capacity save is given by integrating the operation volume with the working capacity divided
into 3.
• Please select the Division Mode appropriate for the system.
• For the proportionally divided power charge (manual input of the electric amount), the calculation is
made in accordance with the operation volume (reference data) of the indoor unit.
• Although “Capacity save” is selected when there are A-control(*1) or K-control units, it will be
automatically changed to “Thermo-ON time”, and perform apportioning billing system. (WHM uni
t
for outdoor units. In all buildings for manual input of watt hour.)
(*1) On Ver. 5.16. and later and Ver. 5. 5* and later, the apportioned electric charge for A-control
units is calculated based on the “Thermo-ON” time if “Capacity save” is selected.
