# Code Description
N/A [8-06] 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 or cool down of a space can
take longer. This setting can compensate for a slow or a quick heating/cooling
system during the heat up/cool down 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 cooling/heating changeover based on the indoor ambient temperature.
Therefore it is important to set this correctly.
# Code Description
[A.3.1.1.7] [9‑0B] Emitter type :
Reaction time of the system:
▪ Quick (default) Example: Small water
volume, fan coils, or radiators.
▪ Slow Example: Large water volume, floor
heating loops.
Quick heat up function
Only applicable in case of room thermostat control. The function will start up the
gas boiler when the actual room temperature is 3°C lower than the desired room
temperature. The large boiler capacity can boost up the room temperature quickly
to the desired temperature. This can be useful after a long period of absence or
after a break-down of the system. During the quick heat up function, the setpoint
of the gas boiler will be the maximum heating setpoint: [9‑00].
