Basic stage heating

Notice
Only available when the "Extended settings" parameter under "Heating control"
is activated.
8.18.9 Basic stage heating — Status object heating
Options:
– The parameter enables the "Status heating" communication object.
8.18.10 Basic stage heating — Mode of the control value
Options:
The mode of the control value can be used to adapt the control value to de-energised opened
(normal) or de-energised closed (inverse) valves.
– Normal: Value 0 means "Valve closed".
– Inverse: Value 0 means "Valve open".
8.18.11 Basic stage heating — Hysteresis
Options:
The hysteresis of the two-point controller specifies the fluctuation range of the controller around
the setpoint value. The lower switching point is located at "Setpoint value minus hysteresis" and
the upper point is at "Setpoint value plus hysteresis".
Notice
This parameter is only available when the "Control value type" parameter is
set either on "2-point 1 Bit, Off/On" or "2-point 1 Byte, 0/100%".
8.18.12 Basic stage heating — Control value difference for sending of heating control value
Options:
The control values of the 0 - 100% PI continuous controller are not transmitted after every
calculation. Instead, they are transmitted when the calculation results in a value that is different
enough to the previous sent value to make a transmission meaningful. This value difference can
