Note
The automatic push only works when DHW operating mode is set.
Excess heat draw (5085)
Excess heat draw-off can be triggered by the following functions: Maxi­
mum storage tank temperature, automatic push, heating priority time push,
excess heat draw-off, active inputs H1, H2, H3 or EX2, storage tank re­
verse cooling, solid boiler excess heat draw-off. If an excess temperature
discharge is activated, the excess energy can be dissipated through the
central heating drawing off heat. This can be separately set for each heat­
ing circuit.
With buffer (5090)
No: The DHW storage tank is supplied directly by the boiler.
Yes: The DHW storage tank is supplied by the buffer storage tank.
With prim contr/system pump (5092)
No: The DHW storage tank is supplied without primary controller/feed
pump.
Yes: The DHW cylinder is supplied from the primary controller on/by the
feed pump.
With solar integration (5093)
This function determines whether the DHW cylinder should be heated by
solar energy.
Pump speed min (5101) andPump speed max (5102)
Setting of the minimum and maximum speed of the storage tank charging
pump in percent.
Speed Xp (5103)
The P-band Xp defines the amplification of the controller. A smaller Xp val­
ue leads to a higher actuation of the charging pump with equal control dif­
ference.
Speed Tn (5104)
The reset time Tn determines the reaction speed of the controller when
compensating for remaining controller differences. A shorter reset time Tn
leads to faster compensating.
Speed Tv (5105)
The preholding time Tv determines how long a spontaneous change of the
control difference continues to have an effect. A short time only influences
the control variable only for a short time.
Transfer strategy (5130)
The transfer is always allowed or to the set DHW release times.
Interm circ boost recharging (5139)
Setpoint boost for charging setpoint on charging sensor B36 with recharg­
ing.
Intermediate circuit boost (5140)
Setpoint boost for charging setpoint on charging sensor B36 with full
charging.
Excess interm circ temp max (5141)
With this parameter the end criterion of a full charging during control is
specified on the charging sensor B36. If the contents of the stratification
cylinder is charged to the bottom, the temperature increases on the charg­
ing sensor
Flow setp compensation delay (5142)
The filter time for the setpoint lead is set here.
