Description
Scaling Input_PER low
Input_PER is scaled based on the two value pairs Upper-
PointOut, UpperPointIn and LowerPointOut, LowerPointIn.
Only effective if Input_PER is used for process value de-
tection (Config.InputPerOn = TRUE).
LowerPointIn < UpperPointIn
Scaled high process value
Input_PER is scaled based on the two value pairs Upper-
PointOut, UpperPointIn and LowerPointOut, LowerPointIn.
Only effective if Input_PER is used for process value de-
tection (Config.InputPerOn = TRUE).
UpperPointOut > LowerPointOut
Scaled low process value
Input_PER is scaled based on the two value pairs Upper-
PointOut, UpperPointIn and LowerPointOut, LowerPointIn.
Only effective if Input_PER is used for process value de-
tection (Config.InputPerOn = TRUE).
LowerPointOut < UpperPointOut
Selecting the output value for heating
Config.Output.Heat.Select specifies which outputs are
used for heating:
Heat.Select = 0 - OutputHeat is used
•
Heat.Select = 1 - OutputHeat and OutputHeat_PWM
•
are used
Heat.Select = 2 -OutputHeat and OutputHeat_PER are
•
used
Outputs that are not used are not calculated and remain at
their default value.
