[8-06]
Leaving water temperature maximum
modulation:
0°C~10°C (default: 3°C)
Requires modulation to be enabled.
This is the value by which the desired
leaving water temperature is increased
or lowered.
INFORMATION
When leaving water temperature modulation is enabled,
the weather‑dependent curve needs to be set to a higher
position than [8-06] plus the minimum leaving water
temperature setpoint required to reach a stable condition
on the comfort setpoint for the room. To increase
efficiency, modulation can lower the leaving water setpoint.
By setting the weather‑dependent curve to a higher
position, it cannot drop below the minimum setpoint. Refer
to the illustration below.

[9-0B]
Reaction time of the system:
▪ 0: Quick.
Example:
Small water
volume and fan coils.
▪ 1: Slow.
Example:
Large water
volume, floor heating loops.
Depending on the system water volume
and the heat emitters type, the heat up
or cool down of a space can take
longer. This setting can compensate for
a slow or a quick heating/cooling
system by adjusting the unit capacity
during the heat up/cool down cycle.
