Parameter description
Setting of maximal difference between stand-pipe and return-
pipe temperature. This way the highest power of heating
system is limited.
Limitation of difference between stand and return pipe is
activated with parameter S1.4=3 (for sensor T1) or S1.5=6
(for sensor T8).
Selection of operation with constant stand-pipe temperature.
Setting range is 10 ÷ 140 °C.
CAUTION: This function deactivates weather compensated
control of mixing valve.
Setting of circulation pump switch-off delay when there is no
requirement for heating.
Parameter description
Set the influence of room temperature deviation. Lower value
means lower influence, higher value means higher influence.
Setting of room sensor T8 influence on the operation of second
circuit.
1- automatic room sensor influence
- room sensor has no influence if room unit DD2+ is
connected
- room sensor has influence if room unit DD2+ isn't
connected
2- room sensor has influence
3- room sensor has no influence
This setting has affect only if S1.5=1.
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.3=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.
