Basic Stage Heating - Pwm Cycle Heating (Min); Basic Stage Heating - Maximum Control Value (0 - 255); Basic Stage Heating - Minimum Control Value For Basic Load (0 To 255) - ABB ClimaECO SBS/Ux.0.1 Series Product Manual

11.4.19 Basic stage heating - PWM cycle heating (min)

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 switch-on phase and a
switch-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".

11.4.20 Basic stage heating - Maximum control value (0 - 255)

Options:
The maximum control value of the PI controller defines the maximum value put out by the
controller. The maximum value will not be exceeded, even if the controller calculates a higher
control value.
Notice
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".

11.4.21 Basic stage heating - Minimum control value for basic load (0 to 255)

Options:
The minimum control value of the PI controller defines the minimum value issued by the
controller. If a minimum value that is greater than zero is selected, the controller will not issue a
lower value, even if it calculates a control value that is lower. This parameter can be used to set
a basic load, e.g. for operating floor heating. Even if the controller calculates the control value
zero, a heating medium will flow through the floor heating system to prevent the floor from
cooling down. Under "Settings of basic load," it is also possible to define whether this basic load
will be permanently active or whether it will be switched by the "Basic load" object.
Notice
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".
