n
0: Decentralised circulation pump (at each station)
The circulation pump is integrated in one or more stations. Set-
tings for circulation and thermal disinfection are made at the sta-
tions with an integrated pump.
n
1: Central circulation pump (at the master).
The circulation pump is installed outside of the stations and is
connected to the master station. Settings for circulation and
thermal disinfection are only made at the master station.
Calibration must be carried out once at the master (manually: ZIR06 =
1). The calibrated flow rate that is determined is transmitted to the
slaves automatically (necessary for sequential changeover).
With regard to cascades with sequential change-
over, the automatic calibration mode (ZIR06 = 2)
results in error messages and is not recommended
for this reason.
The return flow switch can be activated and connected locally on
every device or centrally on one device in the cascade. No further
settings are to be observed in this regard. With regard to central use,
the return sensor also needs to be positioned at the collective return.
WHF00 WARM HOLDING FUNCTION is a local option for each station.
NAC00 RECHARGING PRIMARY is a central option. It is activated and
installed on one device in the cascade and applies centrally to all
devices in the cascade.
Any interruption of charging "11" due to the primary
energy being too low applies to all stations.
The parameters for thermal disinfection are set at the master. The
corresponding info messages are also specified at the master. With
regard to a fixed command station (cascade mode = 0) with a local
circulation pump, the zone valves of the slave stations remain closed
and are therefore not disinfected. If the circulation pump is central
(KAS07 = 1), all zone valves are opened for disinfection to enable flow
through the entire installation.
