Adjustable
Hysteresis The setting of the Hysteresis refers to the boilers starting numbering. For each
starting numbers there is an individually adjustable Hysteresis.
The
Hysteresis enables a gradual ON and turn-OFF of the boilers. See graphic.
Delay Time
The setting of the
Delay Time
refers to the starting numbers of the boilers.
Apart from the starting number 1, each starting number has a Delay Time.
At first it starts only the boiler with the starting number 1. Every other boiler
starts at the end of the Delay Time in which is checked if the boiler or the boilers
can fulfil the requirements. With the buner demand of the boiler with starting
number 1, all Delay Times starts at the same time.
Delay Temp
The setting of the
Delay Temp
refers to the starting numbers of the boiler.
Apart from the starting number 1, each starting number has a Delay Temp. If the
outside temperature is higher than the Delay Temp, there is
no burner demand.
Cascade Base Min The Cascade Base Min is the minimum requirement to the cascade. Falls the
Cascade Base (is calculated from the set values) falls below the Cascade Base
Min
obtains the
Cascade Base Min
. If there is no requirement, the cascade only
activates, if the frost protection function is active (8°C).
Sequence Changes To load the boilers equally, the starting numbers of the boilers change at the
end of the time
Sequence Changes . The time Sequence Changes refers to the
actual boiler run time.
Note:
With setting 0 , no Sequence Change is made! It always starts boiler No.1 at
first.
Peak Load Boiler
The Peak Load Boiler is actually the last boiler (the highest boiler number). It
has the highest starting number.
The
Peak Load Boiler
is excepted from the sequence change. It is only used for
managing energy peaks and always starts at last.
