Additional cooling stage - Control value difference for sending of cooling control value
Options:
2%
5%
10%
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".

11.3.57
Additional cooling stage - Cyclic sending of the control value (min)
Options:
Setting option between 1 - 60 minutes
The current control value used by the device can be cyclically transmitted to the bus.
Note
This parameter is only available when the "Control value type" parameter is set
either on "2-point 1 Bit, Off/On", "2-point 1 Byte, 0/100%", "PI continuous, 0-
100%" or "Fan coil".

11.3.58
Additional cooling stage - Maximum control value (0 - 255)
Options:
Setting option between 0 - 255
The maximum control value of the PI controller defines the maximum value outputted by the
controller. If a maximum value under 255 is chosen, the value will not be exceeded, even if the
controller calculates a higher control value.
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".
