20 Submenu Cascade at the client

20.3 Switchover point OFF*
Here you can define the threshold for the minimum flow rate when the active module is switched
off and the cascade valve closes. The percentage refers to the maximum flow rate of the active
modules.
Please note the automatic connection of the switchover points ON and OFF, a modification can
impact the control performance.
20.4 Switchover delay*
Allows to set a delay after which time a new module is meant to switch on/switch off.
For example, if the threshold for the switching on of a module is exceeded, the next module is
only switched on after the defined switching delay.
20.5 Duration of standby module*
A standby module is a domestic hot water module whose cascade valve is still open at that
moment, even if there is no withdrawal. There is always only one standby module, the other
modules with open cascade valves (if available) are called switch on modules. The domestic hot
water modules alternately assume the role as standby module in order to distribute the
operating hours equally to the modules. Via the menu item, you can define the duration how
long a standby module should be activated before it is exchanged to the next standby module
which has the lowest operation time of the pump.
20.6 Synchronise*
In case of modifications in the menu of the cascade, a separate synchronisation can be required
if the settings are transmitted incorrectly.
In this case, all settings of the client are transmitted again to the connected servers.
