Setting multi-function controllers (MFC)
46
Temperature-controlled
The switching output of the multi-function controller switches on as soon as the
temperature falls below the preset setpoint temperature. If the temperature rises above
the upper limit of the preset temperature range (hysteresis), the switching output
switches off. The sensor must be fitted in the circulation return line.
For this control type 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
Time-controlled
The circulation pump is switched on and off in alternation within a preset time window.
You can configure the setting for the duration of the respective runtime and waiting time.
For this control type you can set the following parameters:
•
Basic settings/MFC 1-6/Runtime, Output
•
Basic settings/MFC 1-6/Waiting time
•
Program/MFC 1-6/Time 1–3 start (stop)
6.8
Setting the "Alarm" function
In the case of this function, the switching output of the multi-function controller switches
on or off when there is a fault on the sensors used. For this function you can set the
following parameters:
•
Basic settings/MFC 1–6/Output, Link.
6.9
Setting the "Timer" function
In the case of this function, the switching output of the multi-function controller switches
on within the preset time window. For this function you can set the following parameters:
•
Basic settings/MFC 1–6/Output
•
Program/MFC 1-6/Time 1–3 start (stop)
6.10
Setting the "HW reheating" function
With this function, the MFC output will be switched on when the hot water request is
active. The HW reheating can thus be implemented in layers using a three-way reversing
valve. No further parameters can be set for this function.
