Setting multi-function controllers (MFC)
48
When the leadfing ouput is switched off, the MFC will also be switched off and reset to its
initial state.
For this function you can set the following parameters:
•
Basic settings/MFC 1–6/output.
•
Basic settings/MFC 1–6/Delayed off period
•
Basic settings/MFC 1–6/Link
•
Program/MFC 1–6/Waiting time

Setting the "Yield" function
With this function you can perform an energy yield measurement via an S0 interface. The
total yield and the day yield then appear in the "Info" menu.
For this function you can set the following parameters:
Basic settings/MFR 1–6/Input S00-S10, S12-S15 (Please note: the inputs S00, S12-S15
respond to +5V at the input)
•
Basic settings/MFC 1–6/Pulse number per kWh

Setting the "Mixer" function (only MFC 1)
With this function you can boost the return line by mixer to the calculated maximum
supply line setpoint tempertaure of the heating circuits.
The multi-function controller uses different setpoint temperatures as reference:
1.
Supply line:
The currently highest supply line setpoint temperature is used as
reference. The mixer is controlled according to the source sensor (e.g. an external heat
source) and sink sensor.
If the source rises above the supply line setpoint tempe hysteresis, the
function will become active and the mixer will adjust to the supply line setpoint
tempe hysteresis.
2.
Hot water:
The hot water setpoint temperature is used as reference. The control
workflow is the same as point 1.
3.
Temperature:
An adjustable target temperature is used as reference. The mixer is
adjusted to this temperature according to the source sensor. If the source rises above
the sink setpoint tempe hysteresis, the function will become active and the
mixer will adjust to the source setpoint tempe hysteresis.
For this function you can set the following parameters:
•
Basic settings/MFC 1/Target type
•
Basic settings/MFC 1/ Output 1 (mixer open), Output 2 (mixer closed)
•
Basic settings/MFC 1/Source sensor, sink sensor
