Low noise mode (on-site modification)
By performing the following modification, operation noise
of the outdoor unit can be reduced by about 3-4 dB.
The low noise mode will be activated when a commer
-
cially available timer or the contact input of an ON/OFF
switch is added to the CNDM connector (option) on the
control board of the outdoor unit.
• The ability varies according to the outdoor temperature
and conditions, etc.
1 Complete the circuit as shown when using the external
input adapter (PAC-SC36NA-E). (Option)
2 SW7-1 (Outdoor unit control board): OFF
3 SW1 ON: Low noise mode
SW1 OFF: Normal operation
Demand function (on-site modification)
By performing the following modification, energy
consumption can be reduced to 0–100% of the normal
consumption.
The demand function will be activated when a commer
-
cially available timer or the contact input of an ON/OFF
switch is added to the CNDM connector (option) on the
control board of the outdoor unit.
1 Complete the circuit as shown when using the external
input adapter
(PAC-SC36NA-E). (Option)
2 By setting SW7-1 on the control board of the outdoor
unit, the energy consumption (compared to the normal
consumption) can be limited as shown below.
