Mode 2: Field settings

In mode 2 you can make field settings to configure the system. The LEDs give a binary representation of the setting/value number.
Setting
[2‑0]
T target evaporating temperature.
e
With this setting the target evaporating temperature can be set in
increments of 5 K.
[2‑1]
T fine‑tuning of evaporating temperature.
e
With this setting the target evaporating temperature set by [2‑0]
can be fine‑tuned in increments of 1 K.
[2‑6]
Address of the outdoor unit for communication with the Modbus
communication box (BRR9A1V1).
For more information, see the installation manual of the Modbus
communication box.
[2‑13]
Correction of evaporating temperature during low‑noise operation.
With this setting the target evaporating temperature set with
settings [2‑0] and [2‑1] can be corrected for low‑noise operation
(see setting [2‑18])
[2‑17]
Adjustment of fan and compressor speed during low‑noise
operation.
With this setting the maximum fan and compressor speed can be
set for low noise operation (see setting [2‑18]).
[2‑18]
Low noise operation
With this setting one of three low‑noise operation modes can be
selected. Low‑noise mode can be activated by turning ON the
contact between terminals X2M/A and X2M/B. Refer to settings
[2‑13] and [2‑17] to set parameters for the low‑noise levels.
