N/A [5-02] Space heating priority.
Defines whether domestic hot water is
made by booster heater only when
outdoor temperature is below space
heating priority temperature. It is
recommended to enable this function to
shorten tank heating operation time
and guaranteed domestic hot water
comfort.
▪ 0: disabled
▪ 1: enabled
[5‑01] Equilibrium temperature and
[5‑03] Space heating priority
temperature are related to backup
heater. So, you must set [5‑03] equal or
a few degrees higher than [5‑01].
N/A [5-03] Space heating priority temperature.
Defines the outdoor temperature which
below the domestic hot water will be
heated by booster heater only.
Range: –15°C~35°C (default: 0°C).
N/A [5-04] Set point correction for domestic hot
water temperature: set point correction
for the desired domestic hot water
temperature, to be applied at low
outdoor temperature when space
heating priority is enabled. The
corrected (higher) set point will make
sure that the total heat capacity of the
water in the tank remains
approximately unchanged, by
compensating for the colder bottom
water layer of the tank (because the
heat exchanger coil is not operational)
with a warmer top layer.
Range: 0°C~20°C (default: 10°C).
N/A [C-00] If a solar kit is installed, what has
priority to heat up the tank?
▪ 0: Solar kit
▪ 1: Heat pump
N/A [C-01] If there is a simultaneous demand for
space heating/cooling and domestic hot
water heating (by heat pump), which
operation mode has priority?
▪ 0: The operation mode with the
highest request has priority.
▪ 1: Always space heating/cooling has
priority.
For systems with an integrated domestic hot water tank (only
for EHVH/X)

Description # Code
N/A [5‑02] Space heating priority.
Defines whether backup heater will
assist the heat pump during domestic
hot water operation.
Consequence: Shorter tank heating
operation time and shorter interruption
of the space heating cycle.
This setting MUST always be 1.
[5‑01] Equilibrium temperature and
[5‑03] Space heating priority
temperature are related to backup
heater. So, you must set [5‑03] equal or
a few degrees higher than [5‑01].
If the backup heater operation is limited
([4‑00]=0) and the outdoor temperature
is lower than setting [5‑03], the
domestic hot water will not be heated
with the backup heater.
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
N/A [C‑01] If there is a simultaneous demand for
space heating/cooling and domestic hot
water heating (by heat pump), which
operation mode has priority?
▪ 0: The operation mode with the
highest request has priority.
▪ 1: Always space heating/cooling has
priority.
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.
# Code
[A.6.1] [3‑00] Is the auto restart function of the unit
