3.2.6 Setting of Low Noise Operation and Demand Operation

(1) Setting of Low Noise Operation

By connecting the external contact input to the low noise input of the external control adaptor for

outdoor unit (optional), you can use low noise operating.

A. When the low noise operation is carried out by external contacts (with the use of

the external control adaptor for outdoor unit)

1. Connect the external adaptor for the outdoor unit, and then connect the external input wiring

to the low noise operation input terminal on the terminal block (TeS1).

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., "Level 1", "Level 2",

or "Level 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 priority) 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., "Level 1", "Level 2", or "Level 3")

for set item No. 22 (Setting of Low night noise operation 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 Low night noise operation).

(Use the start time as a guide since it is estimated according to outdoor air 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 Low night noise operation).

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

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

of capacity priority) 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 night-time.)
