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 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.
