Leaving water temperature: Modulation
# Code Description
[A.3.1.1.5] [8‑05] Leaving water temperature modulation:
▪ 0 (No): Disabled
▪ 1 (Yes): Enabled. The leaving water
temperature is calculated according
to the difference between desired
and actual room temperature. This
allows
better matching of the
heat pump capacity to actual
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.
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. Refer
to the illustration below.

Leaving water temperature: Emitter type
# Code Description
[A.3.1.1.7] [9‑0B] Emitter type:
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.
Quick heat up function
# Code Description
N/A [C‑0A] Indoor quick heat up function:
▪ 0: OFF.
▪ 1 (default): On.
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 quickly boost up the
room temperature to the desired
temperature. This can be useful after
long periods of absence or after a
breakdown of the system.
Domestic hot water control
Only applicable in case an optional domestic hot water tank is
installed.
This is always applicable for Switzerland.
# Code Description
[A.4.1] [6-0D] Domestic hot water Type:
▪ 0 (Reheat only): Only reheat operation
is allowed.
▪ 1 (Reheat + sched.): Same as 2, but
between the scheduled heatup cycles,
reheat operation is allowed.
▪ 2 (Scheduled only): The domestic hot
water tank can ONLY be heated
according to a schedule.
[A.4.5] [6-0E] The maximum temperature that users
can select for the domestic hot water.
You can use this setting to limit the
temperature at the hot water taps.
INFORMATION
If a third‑party tank is present in the system ([E‑07]=6), it is
recommended to set [6‑0D] to "0" (i.e. Reheat only).
