11.8.45 Basic stage cooling — Control value difference for sending of cooling 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".
11.8.46 Basic stage cooling — 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".
11.8.47 Basic stage cooling — PWM cycle cooling (min)
Options:
Setting option between 1 - 60 minutes
In PI PWM, On/off the control value percentage values are converted into a pulse-interval
signal. This means that a selected PWM cycle will be divided into an on-phase and an off-phase
based on the control value. Accordingly, a control value output of 33% in a PWM cycle of 15
minutes results in an On-phase of five minutes and an Off-phase of 10 minutes. The time for a
PWM cycle can be specified here.
Note
This parameter is only available when the "Control value type" parameter is set
on "PI PWM, On/Off“.
