•  Offset 0 - 100% 
•  Default value 0%: Represents the valve start-up value (degree 
of opening) in %. It functions as an offset to the current valve 
position (0% means no accessing of the valve) 
•  DT
min
: 2 … 20 K, factory value: 5 K 
In case of a defect, the tank sensor or flow sensor switches off to 
prevent scalding. 
If hot-water loading is not activated, there is no setpoint for the 
mixed heating circuit. The setpoint for the mixed heating circuit is 
mandatory. 
 
7.2.8  Mode of operation of hot-water control mode "external 
operation"  
If the energy supply for hot-water loading is not provided through 
the district heating valve, no hot-water demand may be sent to the 
heat generator. The following setting needs to be selected for this 
case: 
"Hot Water Circuit" menu, parameter 07 ("Hot-Water Circuit" 
control mode) = 7 (external operation) 
 
The hot-water pre-control is part of the hot-water loading. 
Consequently, the request from storage control is forwarded to 
the hot-water pre-control, which acts according to its function. 
In the "Hot-Water Circuit" "External Operation" control mode, the 
setpoint value from the hot-water pre-control is not forwarded to 
the energy management unit (or the district heating valve).
