S3.6 MAXIMUM STAND-PIPE
TEMPERATURE
Setting of maximum stand-pipe temperature limitation. 20 ÷ 150 °C

85- radiat.
S3.7 STILL STAND OF MI-
XING VALVE CONTROL
Setting of stand-pipe temperature deviation by which the
mixing valve control is in stand-by.
0,2 ÷ 3,0 °C
0,6
S3.8 MIXING VALVE P -
CONSTANT
Setting of mixing valve position correction intensity. Smaller
value means shorter movements, higher value means longer
mixing valve movements.
0,5 ÷ 2,0
1
S3.9 MIXING VALVE I - CON-
STANT
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.
0,4 ÷ 2,5

S3.10 MIXING VALVE D -
CONSTANT
Sensitivity of mixing valve for stand-pipe temperature changes.
Smaller value means low sensitivity, higher value means high
sensitivity.

S3.12 MINIMUM STAND-PIPE
TEMPERATURE IN
COOLING MODE
Setting of minimum stand-pipe temperature in cooling mode.
CAUTION! Too low stand-pipe temperature can cause dewing
of heating bodies and pipelines.
10 ÷ 20 °C
15
S3.13 SHIFT OF TEMPERA-
TURE, REQUIRED TO
ACTIVATE STAND-PIPE
CONTROL
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.
-10 ÷ 10 °C

S3.14 LIMITATION OF
TEMP. DIFFERENCE
BETWEEN STAND AND
RETURN PIPE
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 S1.5=3.
3 ÷ 30 °C

S3.15 CONSTANT STAND-
PIPE TEMPERATURE
Selection of operation with constant stand-pipe temperature.
Setting range is 10 ÷ 140 °C.
CAUTION: This function deactivates weather compensated
control of mixing valve.
0- NO
1- YES

S3.16 CIRCULATION PUMP
SWITCH-OFF DELAY
Setting of circulation pump switch-off delay when there is no
requirement for heating.
0 ÷ 10 min
