Flow setp compensation delay (5142)
With the setpoint control, the heat demand is adjusted so that the
intermediate circuit temperature DHW charging sensor B36 reaches its
setpoint (storage tank setpoint plus intermediate circuit boost). The
setpoint control can be switched on or off with the flow setpoint delay
parameter ("Off" or value between 0 and 60 s). The setpoint control is
delayed by the length of time set under program no. 5142; the temperature
is controlled to the se charging boost.
Flow setp compensation Xp (5143)
The mixer valve P-band Xp defines the amplification of the controller. A
smaller Xp value leads to higher actuation of the charging pump at the
same control difference.
Flow setp compensation Tn (5144)
The mixer valve 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.
Flow setp compensation Tv (5145)
The mixer valve 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 for a short time.
Full charging with B36 (5146)
Here it can be set whether the end of the full charging is detected via the
temperature on the charging sensor B36.
No: The end of the full charging is detected via the temperature on the
upper and lower storage sensor B3 and B31.
Yes: The end of the full charging is detected via the temperature on the
upper storage sensor B3 and on the charging sensor B36.
Min start temp diff Q33 (5148)
The DHW interm circ pump Q33 is only put into operation if the
temperature in the generator circuit is higher than the upper domestic
water storage tank temperature (B3) by at least the temperature difference
set here. This maintains the temperature stratification in the storage tank.
A setting of -3 °C results in the intermediate circuit pump being switched
on as soon as the boiler temperature rises to within 3 °C of the storage
tank temperature at B3.
Excess interm circ temp del (5151)
Control of the burner output on the charging temperature is activated if the
time set here has elapsed since switching on the intermediate circuit
pump.
9.2.17 Configuration
Heating circuit 1 (5710), Heating circuit 2 (5715) and Heating
circuit 3 (5721)
The heating circuits can be switched on or off using this setting. Heating
circuit parameters are hidden in the deactivated state.
Important
This adjustment only affects the heating circuits directly and has
no influence on operation.
DHW sensor B3 (5730)
DHW sensor B3: There is a DHW storage tank sensor available. The
controller calculates the switching points with the corresponding
switching difference from the DHW setpoint and the measured DHW
storage tank temperature.
