• Local entry:
Local action; the local heating circuit is switched on and off
• Central entry:
Central action; depending on the setting made on operating line "Action changeover
functions", either the heating circuits in the segment or those in the entire system are
switched
Assignment of DHW heating is required only if it is controlled by a heating circuit time
program (refer to operating lines 1620 and 5061).
Settings:
• Local heating circuits:
DHW is only heated for the local heating circuit
• All heating circuits in the segment:
DHW is heated for all heating circuits in the segment
• All heating circuits in the system:
DHW is heated for all heating circuits in the system.
With all settings, controllers in holiday mode are also considered for DHW heating.
"Refrigeration request K28" sets the relay parameter at the QX.. for the output of the
refrigeration request.
Depending on the setting (locally / centrally) the request is delivered by the local
cooling circuit or all cooling circuits in the system. This option only applies to the device
with device address 1.
• Local entry:
Consideration is only given to local refrigeration requests
• Central entry:
Consideration is given to all refrigeration requests from the system
When creating a cascade, the controller having address 1 is assigned the role of the
cascade master. That controller then activates the required functionality and displays
the additional operating menus including the cascade-related parameters.
Identification as the cascade master is made either automatically, depending on the
selection made, or can be ready assigned by selecting "Always".
In the case of a cascaded plant, it is recommended to select "Always" on the cascade
master. This selection ensures that the cascade operating menus and common
functions (e.g. common return temperature control) will not be lost should a power
failure occur.

This setting defines the impact of the system time on the controller's time setting. The
impact is as follows:
• Autonomously: The time of day on the controller can be readjusted
The controller's time of day is not matched to the system time
• Slave without remote adjustment: The time of day on the controller cannot be
readjusted
The controller's time of day is constantly and automatically matched to the system
time
