26.1 Cascade settings
The cascade regulates the common operation of two, three and four pellet boilers or 3 pellet boilers and a peak load
boiler. Therefore are cascade systems with and without accumulator.
Cascade settings
is in the Main menu. Cascade settings is
displayed after entering the code in the Main menu.
Cascade settings has following menu items:
Actual values – not adjustable
• Cascade Base
• Switch On Temp Actual
• Switch Off Temp Actual
• Delay Time
• Boiler 1
• Boiler 2
• Boiler 3
• Boiler 4
Set values – adjustable
• Hysteresis
• Delay Time
• Delay Temp
• Cascade Base Min
• Sequence Changes
• Peak Load Boiler
Conditions for a cascade:
• A cascade system with an accumulator is only possible with accumulator No.1.
• If accumulator No.1 is installed all boilers must be assigned to this accumulator (No.1)
• The accumulator pump must be connected to the boiler.
Periphery Learning
Note
Prior to the
Periphery Learning
, all components must be connected properly.
The number of boilers and selection of the switch off sensor in a cascade system with an accumulator must be taken in
the menu Periphery Learning. See Chapter
20 Periphery Learning, page 54
Number of Boilers
Insert the number of boilers. Peak load boilers count
to the number of boilers. Example: 3 Pellematic and
1 Peak load boiler results in a number of 4!
Switch Off Sensor
If an accumulator is present, you can choose the TPO
(AC upper sensor) or the TPM (AC middle sensor) for
the Switch Off Sensor. If there exists no accumulator
in the system, then you do not have this choice.
