10.24.24 Additional heating stage

Notice
Only available when the "Extended settings" parameter under "Control of
additional heating stage" is activated.
10.24.25 Additional heating stage — 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".

10.24.26 Additional stage heating - PWM cycle heating

Options:
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
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.
Notice
This parameter is only available when the "Control value type" parameter is set
on "PI PWM, On/Off".
10.24.27 Additional heating stage — 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
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".
