Only for [4-03]=4 or 5
In this mode, the indoor unit will heat up the domestic hot water tank.
There are several modes for heating up the domestic water tank:
1. Storage
• Scheduled
The unit will heat up the domestic water tank starting from a
scheduled time and untill the domestic hot water storage set
point is reached. Preferally this is done during nighttime
when space heating demand is the lowest (and if applicable,
electric tariffs are low).
• Powerful
The unit will immediately heat up the domestic water tank
untill domestic hot water storage set point upon user request.
2. Reheat
• Scheduled
The unit will heat up the domestic water tank starting from a
scheduled time and untill the reheat set point is reached.
Preferally this is done during the time of day when space
heating demand is lowest.
• Continuous
The unit will continuously heat up the domestic water tank
untill the reheat set point is reached. In this case a balance
with the space heating demand is made, which ever demand
is higher.
INFORMATION
■
For purpose and configuration refer to "5. Field
settings" on page 13.
■
The domestic hot water storage set point can only be
set manually (refer to "Manual operation" on page 7).
■
The domestic hot water reheat set point can only be
set by the setting [6-07]. Refer to "[6] Scheduled
storage and reheat domestic water heating" on
page 15.
■
Any domestic water heating operation is impossible
when the domestic hot water tank is not installed.
NOTICE
The setting [4-03] shall not be modified. The installer
selected the proper setting for your application.
INFORMATION
The status of this setting is only mentioned to indicate
which settings and functions are applicable for your
application.
[4-03]=0, 1, 2, 3, or 4 is only for domestic hot water tank
with built-in electrical booster heater (RKHW*).
[4-03]=5 is only for domestic hot water tank without
electrical booster heater (RKHTS).

Powerful domestic water heating operation

In the case of urgent need of domestic hot water, the domestic hot
water temperature set point can be reached quickly by using the
electrical heater. Powerful domestic water heating operation is forcing
the electrical heater to operate until the domestic hot water
temperature set point is reached.

Quiet mode operation ( )
s
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the sound produced by the outdoor unit drops. This
implies that the indoor heating (cooling) capacity will also drop.
Beware of this when a certain level of heating (cooling) is required
indoors.

4.6. Controller operations

Manual operation

In manual operation, the user manually controls the settings of the
installation. The last setting remains active until the user changes it or
until the schedule timer forces another setting (refer to "Schedule
timer operation" on page 8).
As the controller can be used for a wide variety of installations, it is
possible to select a function which is not available on your
installation. In that case the message

Icon h or c appears on the display as well as the corresponding

temperature.
• Temperature range for heating: 25°C to 55°C
The temperature for heating can be set as low as 15°C (see
"5. Field settings" on page 13). However, the temperature for
heating should only be set lower than 25°C during
commissioning of the installation. When set lower than 25°C,
only the backup heater will operate.
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (as set through field setting [4-02], refer to
"5. Field settings" on page 13).
• Temperature range for cooling: 5°C to 22°C
CAUTION
The actual operation range depends on the values set on
field setting [9].
These values shall be determined based on the
application.
INFORMATION
In heating mode ( h ) or cooling mode (
temperature set point can also be weather dependent (icon
a is shown).
This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case the controller shows the calculated controller
set point. The bi button or
display the actual "shift value" and subsequently, to set the
correct value. This shift value is the temperature difference
between the temperature set point calculated by the
controller and the real set point. E.g. a positive shift value
means that the real temperature set point will be higher
than the calculated set point.
