Description
Minimum on time of the pulse width modulation for heating
(OutputHeat_PWM output)
A PWM pulse is never shorter than this value.
The value is rounded off to:
Heat.MinimumOnTime = n × CycleTime.Value
Heat.MinimumOnTime is only effective if the output for
heating OutputHeat_PWM is selected (Heat.Select = 1)".
100000.0 ≥ Heat.MinimumOnTime ≥ 0.0
Minimum off time of the pulse width modulation for heating
(OutputHeat_PWM output)
A PWM pause is never shorter than this value.
The value is rounded off to:
Heat.MinimumOffTime = n × CycleTime.Value
Heat.MinimumOffTime is only effective if the output for
heating OutputHeat_PWM is selected (Heat.Select = 1)".
100000.0 ≥ Heat.MinimumOffTime ≥ 0.0
Selecting the output value for cooling
Config.Output.Cool.Select specifies which outputs are
used for cooling:
Cool.Select = 0 - OutputCool is used
•
Cool.Select = 1 -OutputCool and OutputCool_PWM
•
are used
Cool.Select = 2 - OutputCool and OutputCool_PER are
•
used
Outputs that are not used are not calculated and remain at
their default value.
Only effective if the cooling output is activated (Con-
fig.ActivateCooling = TRUE).
