Code
Description
N/A
[5‑03]
Space heating priority temperature.
Defines the outdoor temperature which
below the backup heater will assist
during domestic hot water heating.
N/A
[C‑00]
If a solar kit is installed, what has
priority to heat up the tank?
▪ 0: Solar kit
▪ 1: Heat pump
Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the remote controller settings at the time of the
power failure. Therefore, it is recommended to always enable the
function.
If the preferential kWh rate power supply is of the type that power
supply is interrupted, always enable the auto restart function.
Continuous indoor unit control can be guaranteed independent of the
preferential kWh rate power supply status, by connecting the indoor
unit to a normal kWh rate power supply.

Is the auto restart function of the unit
allowed?
▪ 0: No
▪ 1 (default): Yes
Preferential kWh rate power supply
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/3+4) as the safety
thermostat. It is only possible for the system to have
EITHER preferential kWh rate power supply OR a safety
thermostat.

Description
[A.2.1.6]
[D‑01]
Connection to a preferential kWh rate
power supply:
▪ 0 (default): The outdoor unit is
connected to a normal power supply.
▪ 1: The outdoor unit is connected to a
preferential kWh rate power supply.
When the preferential kWh rate signal
is sent by the electricity company, the
contact will open and the unit will go in
forced off mode. When the signal is
released
again,
the
voltage-free
contact will close and the unit will
restart operation. Therefore, always
enable the auto restart function.
▪ 2: The outdoor unit is connected to a
preferential kWh rate power supply.
When the preferential kWh rate signal
is sent by the electricity company, the
contact will close and the unit will go in
forced off mode. When the signal is
released
again,
the
voltage-free
contact will open and the unit will
restart operation. Therefore, always
enable the auto restart function.
Remark:

▪ 3: N/A
See table below.
Setting 2 is only meaningful if the
preferential kWh rate power supply is of
type 1 or indoor unit is connected to a

NOT connected to the preferential kWh
rate power supply.

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.
