108 Cascade settings
The cascade regulates the collective operation from 2 to 4 Pellematic pellet boilers or 3 pellematic pellet boi-
lers and a reserve boiler of another kind.
There exist cascade systems with and without accumulators.
In the windows 1 and 2 no settings can be adjusted.
Measuring values and adjusted settings are displayed.
Not adjustable
Cascade Base The Cascade Base is the calculated source temperature for the function of the
cascade. It results according to the amount of set values. The Hysteresis is ad-
ded to the Cascade Base.
Switch On Temp Actual The Switch on sensor at a accumulator is always the TPO (AC upper sensor)
The Switch on sensor at a hydraulic seperator is the boiler sensor (= coeval the
switch off sensor).
The Switch on sensor maesures the
Switch On Temp Actual .
Switch Off Temp
Actual
The Switch off sensor at a accumulator is the TPO (AC upper sensor) or the
TPM (AC middle sensor)
The switch off sensor at a hydraulic seperator is the boiler sensor (= coeval the
switch on sensor).
The switch on sensor maesures the
Switch Off Temp Actual .
Delay Time
At first starts only one boiler. Each further boilers start after the Delay Time.
You see the remaining Delay Time of each boiler.
Boiler 1– 4 The boilers are numbered from 1 – 4. The numbering equals to the real boilers
numbers. If the font of the boiler 1 is green, it symbolizes a burner demand.
Besides the numbering of the boilers there is the starting numbering. It can be
different to the boilers numbering because of the sequence changes. The set-
tings Hysteresis, Delay Time and Delay Temperature refer to the starting num-
bering of the boiler.
