U802 Low Noise Timer Enabled—Sets the low noise operations of the condenser fan. When the
parameter is set to YES, the low noise operation is selected. When set to NO, the low noise will be
disabled even if a schedule is set below.
U803 Noise Reduction On—Lists the day(s) that the low noise feature can be scheduled if U802 is
set to YES.
NOTE
The low noise feature will be overridden if a high pressure condition occurs. This is a
safeguard to ensure optimal control of the conditioned space.
U804 Whole Days—Selects the whole day(s) low noise operations will be available for the condenser
fan. When the parameter is set to YES, the low noise operation is selected for the whole day. When
set to NO the low noise will be disabled.
NOTE
Coordinate fan reversal time and date with unit Off conditions where applicable. If the
compressor is in operation and/or the fan is in a low noise operation, the request to reverse the
fans will be ignored. This is intended to prevent high-pressure condition.
