Operation
This function decreases noise at night or other times as necessary.
The input signal is recognized during its rising/falling phase.
(After reaching the top/bottom of the rising/falling edge, the signal must remain there for at least 100 ms.)
The optional P.C. board should be connected to the header outdoor unit (U1).
The system’s capacity is reduced during low-noise operation.
The table below provides a rough guide to this capacity reduction.
* Position of noise measuring device: 1 m from the front face of the set and 1.5 m above ground (Measured in
anechoic room)
