S5.6
BOILER STAND-BY AT
MIN. TEMPERATURE
Setting of boiler stand-by at min. boiler temperature.
This setting has affect only if heating operation mode is
active.

TEMP. INCREASE
Setting of solid fuel boiler temperature increase that
causes liquid fuel boiler to switch off. Monitoring period is
2 minutes.
0- NO

S5.12
SOLID FUEL BOILER
PROTECTION TEMP.
Setting of solid fuel boiler protection temperature. If this
temperature is exceeded, controller gradually starts to in-
crease calculated stand-pipe temperature in circuit 1 and 2.
70 ÷ 90 °C
77
S5.13
MAX. SOLID FUEL
BOILER OR HEAT AC-
CUMULATOR TEMP.
Setting of max. solid fuel boiler temperature or heat ac-
cumulator temperature. If this temperature is exceeded
controller transfers surplus heat to d. h. w. storage tank and
heating circuits. Limitation of max. stand-pipe temperature
in heating circuits remains active.
60 ÷ 160 °C
90
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
limitation. Also set parameter S1.4=11 (for sensor T1) or
S1.5=12 (for sensor T8).
10 ÷ 90 °C

S5.15
SWITCHOVER DELAY
TO CONTROLLED HEAT
SOURCE
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

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

S5.17 FLUE GASES TEMP.
FOR SWITCHOVER TO
SOLID FUEL BOILER
In schemes with double fireplace boiler (scheme
#117 and # 118) 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 tempera
-
ture 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
TEMPERATURE
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
