3 About the system
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.
