HEAT METERING PARAMETERS
The procedure for setting function parameters is the same as for service
parameters (see page 30).
Group W contains parameters to set the solar heat metering.
Para-
meter Function Parameter description Setting range Default
value
S3.9 MIN. RPM FOR PUMP R3 Minimum RPM stage for modulation of pump R3.
1- 40 %
2- 55 %
3- 70 %

S3.10 R3 FULL-RPM RUNNING
TIME
When the differential condition is fulfilled, the R3 runs at full
RPM for a setted time. 5 ÷ 300 s 20
S3.13 BOILER CIRCULATION
PUMP - TIME OF BOILER
TEMPERATURE RISE
This function is used to control the solid fuel boiler return-pipe
temperature if there is no sensor installed in the storage tank.
In setted time controller monitors boiler temperature rise of 2 °
C. If there is a rise of 2 °C detected the boiler circulation
pump is activated for a setted time.
30 ÷ 900 s 300
S3.14 BOILER CIRCULATION
PUMP - RUNNING PERIOD
Setting of runnig period for boiler circulation pump if a boiler
temperature rise of 2 °C is detected. Circulation pump is
running until there is a temperature difference between boiler
and boiler return pipe.
30 ÷ 900 s 300
S3.15 ACTUATOR RUNNING TIME
Actuator running time, needed for a 90° turn. This data is
considered at delayed switchovers with valves.
1 ÷ 8 min 2
S3.16 BOILER CIRCULATION
PUMP - OPERATION MODE
This setting defines how boiler circulation pump shall operate:
1- STANDARD means that circulation pump is running accor-
ding to setted minimum boiler temperature and according to
temperature difference between return pipe and boiler tempe-
rature.
2- ALWAYS means that circulation pump is running always
when boiler temperature is higher as setted minimum boiler
temperature. Such operation mode is used for systems of
pellet boiler without sensor in storage tank.
1- STANDARD
2- ALWAYS 1
S3.17 MIXING VALVE P - CON-
STANT
Setting of mixing valve position correction intensity. Smaller
value means shorter movements, higher value means longer
movements.
0,5 ÷ 2,0 1
S3.18 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.
0,4 ÷ 2,5 1
S3.19 MIXING VALVE D - CON-
STANT
Sensitivity of mixing valve for stand-pipe temperature chan-
ges. Smaller value means low sensitivity, higher value means
high sensitivity.
0,0 ÷ 2,5
