as low as possible leaving water temperatures (high efficiency).
This function is only applicable in case of room thermostat control and is used to
calculate the leaving water temperature. After activation, the leaving water
temperature can only be read on the user interface, but not changed. Turn OFF
modulation to change it. The leaving water temperature can either be a fixed
setpoint, or an offset in case of weather-dependent setpoint.

Leaving water temperature maximum
modulation:
0°C~10°C (default: 5°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. See the illustration below.

Leaving water temperature: Emitter type
Only applicable in case of room thermostat control. Depending on the system
water volume and the heat emitters type, the heat up of a space can take longer.
This setting can compensate for a slow or a quick heating system during the heat
up cycle.
Note:
The setting of the emitter type will influence the maximum modulation of
the desired leaving water temperature and the possibility for usage of the
automatic heating changeover based on the indoor ambient temperature.
Therefore it is important to set this correctly.
