Setting multi-function controllers (MFC)
44
For this function you can set the following parameters:
•
Basic settings/MFC 1-6/Source sensor, Output
•
Program/MFC 1-6/Setpoint temperature
•
Program/MFC 1-6/Hysteresis
•
Program/MFC 1-6/Time 1–3: Start (Stop)
6.2
Setting the "Heating" function
In the case of the "Heating" function, the switching output of the multi-function controller
switches on as soon as the temperature falls below the preset switch-on temperature. If
the temperature rises above the upper limit of the preset temperature range (hysteresis),
the switching output of the multi-function controller switches off.
For this function you can set the following parameters:
•
Basic settings/MFC 1-6/Source sensor, Output
•
Program/MFC 1-6/Setpoint temperature
•
Program/MFC 1-6/Hysteresis
•
Program/MFC 1-6/Time 1–3: Start (Stop)
6.3
Setting the "Temperature difference controller"
function
In the case of the "Temperature difference controller" there is a measurement point at
both the source and the sink. If the difference between the temperatures of the two
measurement points exceeds a predefined value, the switching output of the multi-
function controller switches on.
In addition, a minimum temperature can be set at the source and a maximum
temperature at the sink. If the maximum temperature is exceeded or the temperature falls
below the minimum temperature, the switching output of the multi-function controller
switches off.
For this function you can set the following parameters:
•
Basic settings/MFC 1-6/Source sensor, Sink sensor, Output
•
Basic settings/MFC 1-6/Speed
•
Program/MFC 1-6/Tmax sink
•
Program/MFC 1-6/Diff. controller max
•
Program/MFC 1-6/Tmin source
•
Program/MFC 1-6/Diff. controller min
•
Program/MFC 1-6/Time 1–3: Start (Stop)
