Heating: required temperature
difference between entering and

In case a minimum temperature
difference is required for the good
operation of the heat emitters in heating
mode.

[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
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: 3°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.
