Value / Description
H6P
Shows the status of low noise operation.
OFF
Unit is currently not operating under low noise restrictions.
ON
Unit is currently operating under low noise restrictions.
Low noise operation reduces the sound generated by the unit compared
to nominal operating conditions.
Low noise operation can be set in mode 2. There are two methods to
activate low noise operation of the compressor unit and heat exchanger
unit.
▪
The first method is to enable an automatic low noise operation during
night time by field setting. The unit will operate at the selected low
noise level during the selected time frames.
▪
The second method is to enable low noise operation based on an
external input. For this operation an optional accessory is required.
