12) Demand Control
There are two styles of demand operations available as methods of restraining power consumption.
(1) Demand via External Input
Demand input from an external source is carried out from the outdoor unit EXCT (CN030) PCB or the
outdoor unit's serial/parallel I/O (optional).
• Demand control with EXCT input
Short-circuit
Control (range of operations)
2P and 3P 1P and 3P
0 0 No control
0 1 Rated current restricted to A% (A% = 100% at factory shipment)
1 0 Rated current restricted to B% (B% = 70% at factory shipment)
1 1 Control OFF
* The operational current is restricted to either A% or B% as a general indicator during demand input.
• A% and B% can be amended in calibrations of 5% between 70% and 100% with the outdoor unit's
maintenance remote controller.
For details on how to amend the parameters, see the chapter on the outdoor maintenance remote
controller, (Refor to the section "6-6. Settings Modes : Setting the Outdoor Unit EEPROM").
• A% value amendments: Parameters are amended with item code "50" (demand 1).
• B% value amendments: Parameters are amended with item code "51" (demand 2).
(2) Demand Control with No External Input
Demand control is carried out proportionally with the normal settings from the outdoor unit without any
external input.
• Amendments can be made in calibrations of 5% between 70% and 100%.
Refor to the section "6-6. Settings Modes : Setting the Outdoor Unit EEPROM" for the outdoor
maintenance remote controller for details on how to amend the parameters.
Parameters are amended with item code "52" (current control level).
13) Switching to Silent Mode Setup
Two silent mode settings are available: 50dB (A) and 45dB (A).
This setting can be amended with the detailed settings on the outdoor maintenance remote controller.
• Item code "21" : 0 (Setting at shipment) Sets silent mode 50dB (A).
• Item code "21" : 1 Sets silent mode 45dB (A)
