Space cooling operation (
In this mode, cooling will be activated as required by the water
temperature set point.
NOTE
The space cooling temperature set point can only
be set manually (refer to "Manual operation" on
page 5).
Switching between space heating and space
cooling operation can only be done by pressing
the
=
button or by an external room thermostat.
Space cooling operation is not possible if the
installation is a heating only installation.
Domestic water heating operation (
In this mode, the indoor unit will deliver hot water to the domestic hot
water tank when the space heating or space cooling operation has
reached its temperature set point. When necessary and when
allowed by the booster heater schedule timer (refer to "Programming
quiet mode, booster heating or domestic water heating" on page 9),
the booster heater provides auxiliary heating for the domestic hot
water tank.
NOTE
In order to provide domestic hot water throughout
the day, it is advised to keep the domestic water
heating operation on continuously.
The domestic hot water temperature set point can
only be set manually (refer to "Manual operation"
on page 5).

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
booster heater. Powerful domestic water heating operation is forcing
the booster heater to operate until the domestic hot water
temperature set point is reached.
Quiet mode operation (
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the noise produced by the outdoor unit drops. This
implies that the indoor heating and cooling capacity will also drop.
Beware of this when a certain level of heating is required indoors.

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 6).
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

Temperature range for heating: 25°C to 55°C
The temperature for heating can be set as low as 15°C (see
"Field settings" on page 10). 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 "Field
settings" on page 10).

temperature.
In this case, instead of showing the water temperature
set point, the controller shows the "shift value" which
can be set by the user. 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.
