3.1 Components in a typical system layout

Depending on the system layout, the system can:

▪ Heat up a space

▪ Produce domestic hot water

INFORMATION

The purpose of hybrid for multi indoor unit in combination with multi outdoor unit is
for heating only (space heating and DHW (by boiler only)). The target use of the
direct expansion indoor unit (DX) in such a system is for cooling only. A combination
of hybrid and DX, both in heating operation is NOT the main objective of such a
system and hence, the heating comfort or continuous operation of the DX cannot be
guaranteed over the complete operation range.

INFORMATION

When the gas boiler is in maintenance mode, a gas boiler test run is being performed
or changes to settings are being saved, the user interface displays Busy.

If this is the case, the user interface is temporarily disabled so as not to allow

Boiler operation does NOT necessarily imply burner operation. When a heating
demand is sent to the boiler, boiler operation ( ) is continuous, but the burner will
ONLY operate alternately.

INFORMATION

When operation symbol is blinking, then this means that the outdoor unit is
operation in cooling or dry operation. In this case the gas boiler will take over to heat
up the water circuit if required.
