Additional heating stage - Hysteresis (x 0.1°C)
Options:
Setting option between 3 - 255
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".
Note
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%".

Additional heating stage - Control value difference for sending of heating control value
Options:
2 %
5 %
10 %
Send cyclic only
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
be entered here.
Note
This parameter is only available when "Control value type" parameter is set either
on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil".
