Note:
The desired leaving water temperature
can only be read out on the user interface.
[2.C.2]
[8‑06]
Max modulation
:
▪
0°C~10°C
This is the temperature value by which the
desired leaving water temperature is increased or
decreased.
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. See the illustration below.

WD curve type
The weather-dependent curve can be defined using the
2-points

Slope-Offset
method.
