S5.1 MAXIMUM BOILER TEM-
PERATURE
Setting of maximal liquid fuel boiler temperature. 60 ÷ 160 °C
90
S5.2 BURNER HYSTERESIS
AND OPERATION MODE
Setting of burner operation mode and hysteresis.
1- Relay is energized if there is no demand for heating,
regardless to heat source temperature. This way we block
operation of heat sources with independent controller. Such
control is required for Rotex boilers.
2- relay is energized when there is need for heating, re-
gardless to heat source temperature. This way we activate
operation of independent heat sources, such as (wall hung
gas boiler or heat pump).
3 ÷ 20- burner control hysteresis.

S5.3 BOILER TEMPERATURE
INCREASE FOR CIRCUIT
1
Setting of boiler temperature increase in comparison with
calculated stand-pipe temperature for circuit 1.
0 ÷ 25 °C

S5.4 BOILER TEMPERATURE
INCREASE FOR CIRCUIT
2
Setting of boiler temperature increase in comparison with
calculated stand-pipe temperature for circuit 2.
0 ÷ 25 °C

S5.5 BOILER TEMP. INCREASE
FOR D. H. W. WARMING
Setting of boiler temperature increase in comparison with
requested d. h. w. temperature.
0 ÷ 25 °C

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.

S5.7 BURNER SWITCH-OFF
BY SOLID FUEL BOILER
TEMP. INCREASE
Setting of solid fuel boiler temperature increase that
causes liquid fuel boiler to switch off. Monitoring period is
2 minutes.
0- NO
1 ÷ 5 °C

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 ACCU-
MULATOR TEMP.
Setting of max. solid fuel boiler temperature or heat
accumulator 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=9 (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
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.
