S5.14 MIN. BOILER RETURN–PIPE
TEMP. Setting of min. allowed boiler return-pipe temperature for classic
or high-temperture boilers.
This setting is valid only by schemes with boiler return pipe limita-
tion. Also set parameter S1.4=11 (for sensor T1) or S1.5=12 (for
sensor T8). 10 ÷ 90 °C 50
S5.15 SWITCHOVER DELAY TO
CONTROLLED HEAT SOUR-
CE By systems with two heat sources, controller switches to heating
with oil boiler when the deficit of heat occurs. Switchover is carried
out with delay. Smaller value means higher heating comfort due to
shorter delay by switchover, higher value means higher energy
saving due to longer delay by switchover. 0,1 ÷ 3,0 1
S5.16 INVERTED OUTPUT FOR
SWITCHOVER BETWEEN
HEAT SOURCES By schemes with two heat sources it can be set if output for
switchover between two heat sources is inverted. 0- NORMAL
1- INVERTED

S5.17 FLUE GASES TEMP. FOR
SWITCHOVER TO SOLID
FUEL BOILER In schemes with double fireplace boiler (scheme #417 and # 418)
the flue gases sensor can be used to measure solid fuel flue
gases temperature (parameter S1.4=9). In such cases the
switchover from oil boiler to solid fuel boiler is activated also if flue
gases temperature exceeds set-point temperature. Set also
parameter S1.4=9 (for sensor T1) or S1.5=10 (for sensor T8).
70 ÷ 350 °C
130
S5.18 MAX. FLUE GASES TEMPE-
RATURE Setting of max. flue gases temperature. If flue gases temperature
exceeds setted value, controller indicates it. Set also parameter
S1.4=9 (for sensor T1) or S1.5=10 (for sensor T8). 70 ÷ 350 °C 200
S5.19 MIN. FLUE GASES TEMP. OF
SOLID FUEL BOILER Setting of max. flue gasses temperature of solid fuel boiler, above
which the operation of liquid fuel boiler is disabled. This option is
used if the liquid and solid fuel boiler are connected on the same
chimney pipe and is prohibited to have dual boiler operation.
Also set parameter S1.4=12 (for sensor T1) or S1.5=13 (for sen-
sor T8). 50 ÷ 150 °C 100

S6.1 PROTECTION OF MAX.
COLLECTORS OR SOLID
FUEL BOILER TEMPERATU-
RE With this setting is activated protection of max. solar collector or
solid fuel boiler temperature. If solar collector or solid fuel boiler
temprature is exceeded, circulation pump in solar system will
activate although d. h. w. temperature is already reached. 0- NO
1- YES 1
S6.2 MAX. TEMPERATURE OF
COLLECTORS OR SOLID
FUEL BOILER Setting of maximum solar collectors or solid fuel boiler temperature. 90 ÷ 290 °C 120
S6.3 EMERGENCY SHUTDOWN
TEMPERATURE FOR COL-
LECTORS OR SOLID FUEL
BOILER If solar collector or solid fuel boiler emergency shutdown tempera-
ture is exceeded, circulation pump will stop unconditionally.
120 ÷ 350 °C
160
S6.4 COLLECTOR’S FROST
PROTECTION If the temperature drops bellow the set point value (S6.5), the solar
pump switches -on to prevent freezing in the collectors and pipeli-
nes.
NOTE: This setting is suitable only for climates areas where the
temperature only occasionally drops bellow the freezing point. 0- NO
1- YES 0
