5 Configuration
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
After direct expansion units (DX) have operated in cooling
mode, the hybrid for multi indoor unit will not operate by
heat pump for 72hours. During this time, the gas boiler will
take over the hybrid operation.
