(2) Silent mode control
(a) Starting conditions
When all of the following conditions is established
(i) At the start of silent mode initiated by the indoor unit or when the silent mode input is made effective (short-circuited)
at the external input terminal (Factory default: CnG2) on the outdoor unit
(ii) When the outdoor unit operation mode is cooling or heating
(iii) When the outdoor air temperature satisfies the following condition
1) Silent setting 0, 1: Effective in zone A and B
2) Silent setting 2, 3: Effective in zone B
Note (1) Silent setting 0 to 3 can be swiched by [P05] of 7-segment display
.

(iv) It is excluded when the following invalid conditions are established
(For prevention of anomalous pressure rise at start)
• For 30 seconds after either compressor has been turned ON
(During a special operation)
• During the 4-way valve switching safeguard
• During the defrost operation
• During the oil return control
• During the moved pump down control
• During the pump down control for removal of the unit
Note (1) Any controls affected by the restriction of compressor and outdoor fan capcity during the silent mode are excluded.
(b) Sound level (Reference data)
(c) Ending condition
• When the starting conditions are not established
(c) 2-step demand control
(i) Starting condition
If all the following conditions are satisfied.
1) 7-segment display [P04] is set 0%, 40%, 60% or 80% (except OFF).
2) Demand control is in operation.
3) External input connector of outdoor unit for "2-step demand control" is valid.
Ex. "2-step demand input" is valid, when connector (CnS2:[P08]-[9]*) is open.
* CnS1:[P07]-[9], CnG1:[P09]-[9] and CnG2:[P10]-[9] can be used, if they are
not in use.
(ii) Contents of control
Same as the energy saving mode control. [Refer to item (5) on page 41]
(iii) Ending condition
If the start condition is not established.
Energy saving mode control : Not depending on external input, compressor speed is limited by the
setting of 7-segment display [P04]
Demand control : When external input is ON, compressor speed is limited. Demand % is
set with the dip switches SW4-5 andSW4-6.
2-step demand control : When external input is ON, compressor speed is limited. Demand % is
set with the 7-segment display [P04].
Demand 1: Demand control is done by the compressor output % set with SW4-5 and SW4-6.
Demand 2: Demand control is done by the compressor output % set with [P10].
