Setting multi-function controllers (MFC)
You can activate up to 6 multi-function controllers (MFC). The sensors and the output
(incl. HE1-HE3) can be freely assigned. The connected flex-modules can be also used for
that purpose.
The outputs are not linked to the PWM outputs (HE1-HE3). This can be achieved
via a respective link. R0 is not speed-controlled.
You can assign the following functions to the multi-function controllers:
•
"Heating" function
•
"Cooling" function
•
"Temperature difference controller" function
•
"Threshold value switch" function
•
"Return flow boost" function
•
"Wood-fired boiler" function
•
"Circulation" function
•
"Alarm" function
•
"Timer" function
•
"HW reheating" function
•
"Temperature range" function
•
"Modulation" function
•
"Cascade" function
•
"Yield" function
•
"Mixer" function (only MFC 1)
•
"Valve" function (only MFC 2)
•
"Storage tank cooling" function (only MFC 3)
You can select the function for the required multi-function controller in:
•
Basic settings/MFC 1–6/Function.

Setting the "Cooling" function
In the case of the "Cooling" function, the switching output of the multi-function controller
switches on as soon as the preset switch-on temperature is exceeded. If the temperature
drops below the lower limit of the preset temperature range (hysteresis), the switching
output of the multi-function controller switches off.
