Power saving function
Defines whether the outdoor unit power supply can be interrupted
(internally by indoor unit control) during stand-still conditions (no
space heating/cooling nor domestic hot water demand). The final
decision to allow power interruption of the outdoor unit during
standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
To enable the power saving function setting, [E-08] needs to be
enable at the user interface in combination with the removal of the
power saving connector at the outdoor unit. The power saving
connector at the outdoor unit shall only be removed when the main
power supply to the application is switched OFF.

Only applicable for EHBH/X04+08 + EHVH/X04+08. See
"5 Application guidelines" on page 6 for detailed information about
