6627 Refrigeration demand

Locally¦ Centrally

6631 Ext source with eco mode

Off ¦ On DHW ¦ On

These settings are only relevant for device address 1.

The range of action of central changeover can be defined.

This applies to the following types of limitation:

•

Summer changeover (when selecting ”Central“ on line 6623)

•

Summer changeover (with ”Central“ setting on operating line 6621)

Entries:

• Segment: Changeover takes place with all controllers in the same segment.

•

System: Changeover takes place with all controllers in the entire system (in all

segments). The controller must be located in segment 0!

The scope of summer changeover is as follows:

•

Local entry:

Local action; the local heating circuit is switched based on operating lines 730, 1030

and 1330.

•

Central entry:

Central action; depending on the setting made on operating line “Action changeover

functions“, “ either the heating circuits in the segment or those of the entire system

are switched based on operating line 730.

The scope of the operating mode changeover via input H is as follows:

•

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 of the entire system are

switched based on operating line 730.

The range of action of summer changeover is as follows:

•

Local entry:

Local action; the local source is locked.

•

Entry segment:

Central action; all sources of the cascade are locked.

Assignment of DHW heating is required only if it is controlled by a heating circuit

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 demand K28" sets the relay parameter on the QX.. for the output of the

refrigeration demand.

Depending on the setting (local/central) the demand is transmitted by the local cooling

circuit or all cooling circuits in the system. This option applies only to the device with

device address 1.
