[8‑06]
Max modulation
:
▪
0°C~10°C
This is the temperature value by which the
desired leaving water temperature is increased or
decreased.
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.

Shut off valve
The following is only applicable in case of 2 leaving water temperature zones. In
case of 1 leaving water temperature zone, connect the shut-off valve to the
heating/cooling output.
The shut off valve for the main leaving water temperature zone can close under
these circumstances:
INFORMATION
During defrost operation, the shut-off valve is ALWAYS opened.
During thermo
: If [F‑0B] is enabled, the shut off valve closes when there is no
heating demand from the main zone. Enable this setting to:
▪
avoid leaving water supply to the heat emitters in the main LWT zone (through
the mixing valve station) when there is request from the additional LWT zone.
▪
activate the ON/OFF pump of the mixing valve station ONLY when there is
demand.
