Description
Config.Output.Heat.PwmUpper-
Scaling
REAL 100.0 Scaled high PWM output value for heating
Heat.PwmUpperScaling and Heat.PidUpperLimit form a
value pair for scaling of the PID output value (PidOut-
putSum) to the pulse-width modulated output value for
heating (OutputHeat_PWM).
The OutputHeat_PWM value is always located between
Heat.PwmUpperScaling and Heat.PWMLowerScaling.
Heat.PwmUpperScaling is only effective if Out-
putHeat_PWM is selected as output for heating
(Heat.Select = 1)
100.0 ≥ Heat.PwmUpperScaling ≥ 0.0
Heat.PwmUpperScaling ≠ Heat.PwmLowerScaling
Config.Output.Heat.PwmLower-
Scaling
REAL 0.0 Scaled low PWM output value for heating
Heat.PwmLowerScaling and Heat.PidLowerLimit form a
value pair for scaling of the PID output value (PidOut-
putSum) to the pulse-width modulated output value for
heating (OutputHeat_PWM).
The OutputHeat_PWM value is always located between
Heat.PwmUpperScaling and Heat.PwmLowerScaling.
Heat.PwmLowerScaling is only effective if OutputHeat
_PWM is selected as output for heating (Heat.Select = 1)
100.0 ≥ Heat.PwmLowerScaling ≥ 0.0
Heat.PwmUpperScaling ≠ Heat.PwmLowerScaling
Config.Output.Heat.PerUpper-
Scaling
REAL 27648.0 Scaled high analog output value for heating
Heat.PerUpperScaling and Heat.PidUpperLimit form a
value pair for scaling of the PID output value (PidOut-
putSum) to the analog output value for heating (Out-
putHeat_PER).
The OutputHeat_PER value is always located between
Heat.PerUpperScaling and Heat.PerLowerScaling.
Heat.PerUpperScaling is only effective if OutputHeat_PER
is selected as output for heating (Heat.Select = 2)
32511.0 ≥ Heat.PerUpperScaling ≥ -32512.0
Heat.PerUpperScaling ≠ Heat.PerLowerScaling
Config.Output.Heat.PerLower-
Scaling
REAL 0.0 Scaled low analog output value for heating
Heat.PerLowerScaling and Heat.PidLowerLimit form a
value pair for scaling of the PID output value (PidOut-
putSum) to the analog output value for heating (Out-
putHeat_PER).
The OutputHeat_PER value is always located between
Heat.PerUpperScaling and Heat.PerLowerScaling.
Heat.PerLowerScaling is only effective if OutputHeat_PER
is selected as output for heating (Heat.Select = 2)
32511.0 ≥ Heat.PerLowerScaling ≥ -32512.0
Heat.PerUpperScaling ≠ Heat.PerLowerScaling
