DHW sensor: The controller releases the domestic water preparation
with immersion heater within the release time, depending on the storage
tank temperature. The current domestic water setpoint in the controller is
complied with. If the sensor input B3 is designed as a thermostat, the
temperature will be regulated on the basis of the contact. The manual
push can be activated. If the Legionella function is active, charging will
be carried out until the Legionella setpoint is reached.
Important
To ensure that the setpoint control works correctly, the thermostat
outside of the controller must be set to the maximum storage tank
temperature.
Automatic push (5070)
The DHW-push can activated manually or automatically. It causes a one-
time DHW charging to the nominal setpoint.
Off: The DHW-push can only activated manually.
On: If the DHW temperature drops by more than two switching
differences (prog. no. 5024) below the reduced setpoint (prog. no.
1612), it will be recharged once to the DHW nominal setpoint
(prog.no.1610).
Important
The automatic push only works if the domestic water operating
mode is activated (ON).
Excess heat draw (5085)
Excess temperature discharge can be triggered by the following functions:
active inputs Hx
Buffer storage tank recooling
Solid fuel boiler excess temperature discharge
If an excess temperature discharge is activated, the excess energy can be
dissipated through the heat discharge of the domestic water storage tank.
With buffer (5090)
If a buffer storage tank is present, it is necessary to enter whether the
domestic water storage tank can be supplied heat from the heat 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 sets whether the domestic water storage tank can be
charged using 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
value leads to a higher actuation of the charging pump with equal control
difference.
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.
