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 method or the
Slope-Offset method.

Modulation:
▪ 0 No (disabled)
▪ 1 Yes (enabled)
Note: The desired leaving water temperature
can only be read out on the user interface.
