Parameter description
Setting of DD2+ room sensor influence on the operation of
first circuit.
1- influence has only room unit DD2+ controlling the first
circuit (coding switch on room unit S.2=OFF). It can be set on
first, second or both room units.
2- influence has only first room unit DD2+ (coding switch on
room unit S.4=OFF)
3- influence has only second room unit DD2+ (coding switch
on room unit S.4=ON)
5- room unit DD2+ has no influence
Setting of pump operation mode. Settings have the following
meaning:
1- STAND. (circulation pump of mixing circuit - regular)
2- pump switches off, if requested room temperature is
reached (only direct circuit)
3- operation according to time program P1
4- operation according to time program P2
5- SEL. PROG. (operation according to selected time
program)
Setting of minimum stand-pipe temperature limitation, when
heating is active.
Setting of maximum stand-pipe temperature limitation.
Setting of stand-pipe temperature deviation by which the
mixing valve control is in stand-by.
Setting of mixing valve position correction intensity. Smaller
value means shorter movements, higher value means longer
mixing valve movements.
Setting of mixing valve control frequency - how often mixing
valve position is being controlled. Smaller value means low
frequency, higher value means higher frequency of mixing
valve corrections.
Sensitivity of mixing valve for stand-pipe temperature chan-
ges. Smaller value means low sensitivity, higher value means
high sensitivity.
Setting of maximum floor temperature limitation by floor
heating.
Setting is active only if floor sensor is installed and parameter
S1.4=2 (for sensor T1) or S1.5=5 (for sensor T8).
Setting of minimum stand-pipe temperature in cooling mode.
CAUTION! Too low stand-pipe temperature can cause dewing
of heating bodies and pipelines.
Shift of calculated min. stand-pipe temperature by which the
mixing valve control will activate.
Negative values mean activation of mixing valve control by
lower calculated stan-pipe temperatures, positive values
mean activation of mixing valve control by higher calculated
stand-pipe temperatures.
