Setting of Demand Operation
By connecting the external contact input to the demand input of the external control adaptor for
outdoor unit (optional), the power consumption of unit operation can be saved suppressing the
compressor operating condition.
: However the demand operation does not occur in the following operation modes.
(1) Startup control
(2) Oil return control
(3) Defrost control
(4) Pump down residual control
If carrying out demand or low noise input, connect the adaptor’s terminals as shown below.
A. When the demand operation is carried out by external contact (with the use of the
external control adaptor for outdoor unit).
1. Connect external control adaptor for outdoor unit and short circuit terminals as required
(Refer to the figure above).
2. While in setting mode 2, set the item 2-12 (External low noise or demand setting) to ON.
3. If necessary, while in setting mode 2, select a demand 1 level for the item 2-30.
B. When the constant demand operation is carried out. (Use of the external control
adaptor for outdoor unit is not required.)
1. While in setting mode 2, set the item 2-32 (Constant demand setting) to Level 1.
While in setting mode 2, select a demand 1 level for the item 2-30.
