4.4.2 Buffer tank - Temperatures
System menu
Buffer tank
Heating circuit release from following buffer tank
temperature
Temperature value which must be reached to release the
heating circuit pumps in the top part of the buffer tank.
NOTICE! This parameter applies for all available heating
circuits!
Boiler start if difference between boiler setpoint and top
buffer is larger
If the difference between the upper buffer tank
temperature and the boiler temperature setpoint is greater
than the specified value, the boiler starts.
Start of buffer tank charging from charge
Prerequisite: Master boiler in the cascade or hydraulic
system 4
If the buffer tank charge is below the specified value, the
boiler starts.
100% boiler control output when buffer charge is lower
than
Prerequisite: Master boiler in the cascade or hydraulic
system 4
If the buffer tank charge is below the specified value, the
boiler system runs at nominal load.
0% boiler output if buffer charge is over
Prerequisite: Master boiler in the cascade or hydraulic
system 4
If the buffer tank charge is greater than the specified value,
the boiler system follows the shutdown procedure.
Storage tank charge is 100% at boiler setpoint parameter
Prerequisite: Master boiler in the cascade or hydraulic
system 4
The storage tank charge is 100% if the average
temperature of the storage tank is below the specified
boiler temperature setpoint by the specified value. This
parameter defines the end point of the charging curve of
the storage tank.
Buffer tank charge is 0% at the following temperature
(absolute value)
Prerequisite: Master boiler in the cascade or hydraulic
system 4
The buffer tank charge is 0% if the average temperature of
the buffer tank reaches the specified value. This parameter
defines the base point of the charging curve of the buffer
tank.
Buffer tank fully loaded if temperature difference between
boiler and bottom buffer tank
From this difference between the boiler temperature
setpoint that has been set and the current temperature in
the lower part of the buffer tank, buffer tank loading is
stopped.
Storage tank – storage tank difference
Prerequisite: Variant 3
Difference, which must be given for loading a storage tank
e.g. in an adjacent building. If this difference is not
reached, the storage tank loading stops.
