External thermostat
The storage tank is charged with an external thermostat without setpoint compensation
of the controller.
DHW sensor
The storage tank is charged with an electric immersion heater, with setpoint
compensation from the controller.
To ensure that setpoint compensation operates as required, the external control
thermostat must be set to the minimum storage temperature.

Excess heat draw can be triggered by the following functions:
-
Inputs H1, H2, H3 or EX2
-
Storage tank recooling
-
Solid fuel boiler excess heat draw
When dissipation of excess heat is activated, it can be drawn by space heating. This
can be adjusted separately for each heating circuit.
Line no. Operating line
5090 With buffer storage tank
5092 With prim contr/system pump
5093 With solar integration
If there is a buffer storage tank, specify whether the DHW storage tank can draw heat
from it.
When using alternative heat sources, the buffer storage tank temperature is used as a
control criterion for the release of additional heat sources.
It is to be set whether the DHW storage tank receives its heat via the primary controller
or with the help of the system pump (depending on the type of plant).
It is to be set whether the DHW storage tank receives its heat from the solar collectors.
