2 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.

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.

3.3.2 Room thermostat control - Using the
leaving water temperature home pages
INFORMATION
The leaving water is the water that is sent to the heat
emitters. The desired leaving water temperature is set by
your installer in accordance with the heat emitter type.
Example: Underfloor heating is designed for lower leaving
water temperature than radiators and heat pump
convectors and/or fan coil units. You only have to adjust
leaving water temperature settings in case of problems.
For more information about the leaving water temperature, see the
user reference guide.

INFORMATION
When the DHW tank mode is reheat, the risk for capacity
shortage and comfort problem is significant. In case of
frequent reheat operation, space heating function is
regularly interrupted.
Scheduled mode
In scheduled mode ( ), the DHW tank produces hot water
corresponding to a schedule. The best time to allow the tank to
produce hot water is at night, because the space heating demand is
lower.

Scheduled + reheat mode
In scheduled + reheat mode (  ), the domestic hot water control is
the same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (=reheat tank temperature –
hysteresis value; example: 35°C), the DHW tank heats up until it
reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.
