12.34.24 Basic stage heating – Cyclic sending of the control value (min)
Options
Input from 1 to 60
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".
The current control value used by the device can be cyclically transmit to the bus.
12.34.25 Basic stage heating – PWM cycle heating (min)
Options
Input from 1 to 60
Note: This parameter is only available when the "Control value type" parameter
is set on "PI PWM, On/Off“.
In PI PWM, On/off the control value percentage values are convert 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 min. results in an "On-phase" of five minutes and an "Off-phase" of 10
min. The time for a PWM cycle can be specified here.
12.34.26 Basic stage heating – Maximum control value
Options Input from 0 to 255
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".
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.
12.34.27 Basic stage heating – Minimum control value for basic load
Options Input from 0 to 255
