4.4.4 Buffer tank - Service
Enable heating circuit pump 0 according to top
buffer temp
▪ NO: Enable heating circuit pump 0 according to the
boiler temperature parameter „Minimum boiler
temperature to release all pumps“
▪ YES: Enable heating circuit pump 0 according to the
temperature in the upper part of the buffer tank
parameter “Heating circuit release from
following buffer tank temperature”Heating
circuit release from following buffer tank temperature“
Sensor input of buffer tank top sensor
Sensor input to which the sensor in the top part of the
buffer tank is connected.
Sensor input of buffer tank sensor 2-7
The number of sensors displayed depends on the
configuration. All of the configured sensors are used to
calculate the buffer tank charge status.
Sensor input of buffer tank middle sensor
Sensor input to which the sensor in the mid area of the
buffer tank is connected.
Sensor input of buffer tank bottom sensor
Sensor input to which the sensor in the bottom part of the
buffer tank is connected.
Pump output of buffer tank pump
Pump outlet to which the buffer loading pump is
connected.
Control of buffer tank pump
Definition of control signal for pump type used.
Ü "Activation options of pump outlets" [}96]
Minimum buffer tank pump speed
Adjustment of the minimum speed to the pump type (set
mode of pump in accordance with pump manufacturer).
Maximum buffer tank pump speed
If for system operation reasons you need to limit the
maximum speed of the buffer tank loading pump you can
do so by adjusting this parameter.
If the boiler is active then charge all buffer tanks
Prerequisite: Variant 3 or variant 4
YES: Starting the boiler due to a heating requirement by
the buffer tank in the boiler system loads not only this
buffer tank, but all of the buffer tanks in sub-stations. This
increases the runtime related to a boiler system start.
Pump outlet for buffer tank relief valve
The switch valve switches off part of the layered tank until
an adjustable temperature has been reached in the top
layer of the tank so that the boiler reaches the
temperature more quickly. Once this temperature has
been reached, the switch valve switches back and the
entire volume of the layered tank is available to the boiler.
Invert pump outlet for buffer relief valve
▪ YES: If the valve switches incorrectly, the way it is
controlled can be changed using this parameter.
