Power saving function
INFORMATION
Only applicable for ERLQ004~008CAV3.
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
enabled on the user interface in combination with the removal of the
power saving connector at the outdoor unit.
NOTICE
The power saving connector at the outdoor unit shall only
be removed when the main power supply to the application
is switched OFF.
