2.1.5 Setting of Low Noise Operation and Demand Operation

Setting of Low Noise Operation

By connecting the external contact input to the low noise input of the outdoor unit external

control adaptor for outdoor unit (optional), you can lower operating noise by 2-3 dB.

A. When the low noise 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 terminal of low noise

(Refer below figure).

If carrying out demand or low-noise input, connect the adaptor’s terminals as shown below.

2. While in "Setting mode 2", set the setting condition for set item No. 12 (Setting of external

low noise/demand operation) to "YES".

3. If necessary, while in "Setting mode 2", select the setting condition (i.e., "Mode 1", "Mode 2",

or "Mode 3") for set item No. 25 (Setting of external low noise level).

4. If necessary, while in "Setting mode 2", set the setting condition for the set item No. 29

(Setting of capacity precedence) to "ON".

(If the condition is set to "ON", when the air-conditioning load reaches a high level, the low

noise operation command will be ignored to put the system into normal operation mode.)

B. When the low noise operation is carried out automatically at night (The external

control adaptor for outdoor unit is not required)

1. While in "Setting mode 2", select the setting condition (i.e., "Mode 1", "Mode 2", or "Mode 3")

for set item No. 22 (Setting of nighttime low noise level).

2. If necessary, while in "Setting mode 2", select the setting condition (i.e., "20:00", "22:00", or

"24:00") for set item No. 26 (Setting of start time of nighttime low noise operation).

(Use the start time as a guide since it is estimated according to outdoor temperatures.)

3. If necessary, while in "Setting mode 2", select the setting condition (i.e., "06:00", "07:00", or

"08:00") for set item No. 27 (Setting of end time of nighttime low noise operation).

(Use the end time as a guide since it is estimated according to outdoor temperatures.)

4. If necessary, while in "Setting mode 2", set the setting condition for set item No. 29 (Setting

of capacity precedence) to "ON".

(If the condition is set to "ON", when the air-conditioning load reaches a high level, the

system will be put into normal operation mode even during nighttime.)
