Description of the operation modes

Basic domestic water heating operation (

w

)

In this mode, the indoor unit will heat up the domestic hot water tank.

There are 2 basic domestic water heating modes: continuous mode
and scheduled timer mode. All heating will be activated as required
by the water temperature set point. The set point can be set manually
or auto adaptive (refer to "Auto adaptive set point operation" on
page 9).

Continuous operation

In continuous operation mode, the domestic water is always heated
up to the required set point. As soon as the domestic water
temperature is lower than the set point temperature (taking into
account the heat pump ON differential), the heating up of the
domestic water will start automatically. This operation mode remains
enabled until the schedule timer button is pressed (refer to "Schedule
timer operation" on page 7).

As the controller has a wide variety of functions, it is possible to
select a function which is restricted at a certain moment. In that case
the message 

n

 will appear.

Switching on domestic water heating (

w

)

1

Switch on the unit by pushing the 

Y

 button.

The operation LED 

0

 lights up.

2

For continuous operation the 

p

 icon must be OFF.

3

Use the 

wi

 and 

wj

 buttons to set the desired water

temperature.

The temperature range for heating is by default 35°C to 60°C.
This means that in default operation only the heat pump will heat
up the water.

For temperatures higher than 60°C (until 75°C maximum) refer
to the field settings explained in the installation manual.

In order to avoid freezing of installation space, heating by the
heat pump is not operable when the indoor ambient temperature
drops below a certain temperature (refer to the field settings
explained in the installation manual). The booster heater will
take over the heating proces.

The clock needs to be set manually. Adjust the setting
when switching from summertime to wintertime and vice
versa.

INFORMATION

The domestic hot water temperature set point can also be
auto adaptive (icon 

a

 is shown).

This means that the controller calculates the water
temperature set point based on the history of use of
domestic hot water.
