2) Setting M10UKCV-E at 16 rps, M13UKCV-E
at 20 rps and M16UKCV-E at 26 rps as the
maximum operating compressor motor
speed, the minimum capacity operation range
is widened every 1 hour and 2 hours have
passed after ECONO. operation had started.
3) Maximum operating compressor motor speed
lowers up to 37 rps when the ECONO.
instruction is sent from even a room.
