# Code
[A.3.1.3.1] [9-09] Heating: required temperature
difference between entering and
leaving water.
In case a minimum temperature
difference is required for the good
operation of the heat emitters in heating
mode.
[A.3.1.3.2] [9-0A] Cooling: required temperature
difference between entering and
leaving water.
In case a minimum temperature
difference is required for the good
operation of the heat emitters in cooling
mode.
Leaving water temperature: Modulation
# Code
[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
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.

INFORMATION
T a
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.

Description
Leaving water temperature maximum
modulation:
0°C~10°C (default: 3°C)
Requires modulation to be enabled.
This is the value by which the desired
leaving water temperature is increased
or lowered.

Description
Reaction time of the system:
▪ 0: Quick (default)
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.
Description
Domestic hot water Type:
▪ 0 (Reheat only): Only reheat operation
is allowed.
▪ 1 (Reheat + sched.)(default): 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.
