Mode 1 (and default situation): Monitoring
settings
In mode 1 (and in default situation) you can read out some
information. What you can read out differs depending on the model.
7‑LEDs display – Default situation (H1P OFF)
(in case of 5 HP)
You can read out the following information:
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.
