Temp increase: If the return temperature of the consumers is lower than
the temperature on the selected sensor (prog. no. 4795), the return flow
can be preheated by redirecting over the lower part of the storage tank.
In this way, for example, return flow preheating can be implemented.
Partial charging setpoint (4800)
As a result of the hydraulic uncoupling of the lower part of the buffer
storage tank, the volume of the storage tank to be heated is reduced. The
remaining, upper part of the storage tank is therefore charged faster. The
lower part of the storage tank is heated up first if the upper part of the
storage tank is charged.
As soon as the temperature measured on the Buffer sensor B4/B42 has
reached the target partial charging value, the changeover valve switches
to "Pass though" and the rest of the storage tank is also charged. To do
this, a Buffer return valve Y15 and a Buffer sensor B4 or Buffer sensor
B42 must be configured.
Full charging (4810)
The {1}full charging{2} function enables the released generator to be
switched off first despite the automatic generator lock if the buffer storage
tank is fully charged. During active function the generator parameterized
for the full charging function is only switched off when the full charging
setpoint is reached or the boiler must be switched off because of burner
control.
Off: The full charging function is switched off.
Heating mode: Full charging becomes active if the automatic generator
lock blocks the heat source during valid heat request based on the
buffer temperature. If the buffer storage tank reaches the requested
temperature at the sensor parameterized for the full charging function,
the function is ended.
Always: Full charging becomes active if the automatic generator lock
blocks the generator during valid heat request based on the buffer
temperature or the heat request is invalid. If the buffer storage tank
reaches the requested temperature at the sensor parameterized for the
full charging function, the function is ended.
Full charging temp min (4811)
The buffer storage tank is charged minimally o the set value.
Full charging sensor (4813)
With B4: For the full charging function the buffer storage tank sensor B4
is considered.
With B42/B41: For the full charging function the buffer storage tank
sensor B42, if not available buffer storage tank sensor B41, is
considered.

DHW storage tank

DHW storage tank
The domestic water storage tank can be charged in a variety of ways:
Via solar collectors
Via the buffer storage tank
Via the oil/gas boiler, the solid fuel boiler or the cascade
Via an additional generator
Via an immersion heater
The options available depend on the available components and their
configuration. If required, the components can complement each other in
the order that is most efficient in terms of energy use.
Forward shift charging (5011)
This setting only has an effect if the domestic water release is set in
accordance with the time switching program of the heating circuit.
