The standardized signal output (terminals 11/12) is not avail-
able anymore as a control output. The maximum flow set point
(with boost, if applicable) is demanded as a 0 to 10 V signal at
the standardized signal output.
Function block parameters:
Lower transmission range: 0.0 to 130.0 °C (0.0 °C)
Upper transmission range: 0.0 to 130.0 °C (120.0 °C)
