If the switch-off threshold is not reached, the most recently acti-
vated station is shut down. The stations that are still active continue
to control the domestic hot water setpoint temperature TWWset. The
switch-off threshold corresponds to the speed of the primary pump
and can be adjusted via
KAS06 SWITCH-OFF POINT CAS.
. A defined time
KAS03 TIME LAG STATION
must be undershot in relation to this
threshold.
The switch-off threshold should always be greater
than the minimum speed of the primary pump
STE03
MIN SPEED PRIM. PUMP
.
For each station in the cascade, STN 1 ... 5 for short, a 4-digit status
is displayed in the master
STN1 ... 5 STATUS STATION CAS.
.
Digit 1= sequential number of
the station
0: Station not available
1...5: Current position in the
cyclical change from station 1 to
5
Digits 2...4 = Information about
the current status of the respec-
tive station
0: Off
1...100: Overmodulation in s %
101: Not ready, no power
102: Standby
103: Controlling

Commissioning the cascade
If a station is to be used in a cascade, the value
KAS01 OPERATING
MODE STATION
needs to be set.
n
0: Standalone
n
1: Slave (subordinate station in the cascade)
n
2: Master (main controller in the cascade)
One device in the cascade must be set to 2. The
other devices are set to 1.
