S6.6 OPERATION OF LIQUID
FUEL BOILER Setting if d. h. w. warming with oil boiler and solar collectors or solid
fuel boiler can operate at the same time or oil boiler shall activate
with delay after warming with solar collectors or solid fuel boiler has
been stopped. -1- PARALELL

S6.8 SOLAR PUMP KICK FUNC-
TION Special algorithm activates the solar pump to switch -on for short
intervals. This way realistic temperature of collectors is obtained.
This function is used especially with vacuum (tube) collectors or
with classic collectors if the sensor is fitted outside of the collector
body. 0- NO

TURE OF COLLECTORS OR
SOLID FUEL BOILER We define whether and how the minimum collector or solid fuel
boiler temperature is respected. 0- NO

S6.10 OPERATION MODE OF
COLLECTORS OR SOLID
FUEL BOILER CIRCULATI-
ON PUMP Setting of circulation pump ON/OFF or RPM operation mode. RPM
modulation of the pump is done with 5 stages (40 %, 55 %, 70 %,
85 %, 100 % RPM). 0- ON/OFF
1- RPM 1
S6.11 MINIMUM RPM FOR PUMP Minimum RPM stage for modulation of circulation pump.
1- 40 % RPM
2- 55 % RPM

3- 70 % 1
S6.12 FULL-RPM RUNNING TIME
OF COLLECTORS OR SOLID
FUEL BOILER CIRCULATI-
ON PUMP When the differential condition is fulfilled, the circulation pump runs
at max. RPM for a setted time. Afterwards the pump is running with
RPM modulation (if enabled with parameter S6.10=1). 5 ÷ 300 s 20
S6.13 LOCATION OF COLD SEN-
