Service settings for boilers:
Para-
meter Parameter name Parameter description Setting range Default
setting
S5.1 MAXIMUM BOILER TEMPE-
RATURE 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.
0- relay is energized when there is need for heating, regardless to
heat source temperature. This way we activate operation of in-
dependent heat sources, such as (wall hung gas boiler or heat
pump).
1 ÷ 20- burner control hysteresis. -1- SWITCH-
OFF
0- SWITCH-ON
1- 20 °C-
HYSTERESIS 8
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 5
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 5
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 10
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. 0- ON
1- DAY TEMP.
PERIOD
2- OFF 2
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 4
S5.8 DELAY OF REPEATED
BOILER SWITCH-ON With this setting, we determine the delay time after which the boiler
can be switched on again. The delay starts when the boiler is
switched off and until the delay expires, repeated switch-on of the
boiler will be disabled. 0 ÷ 30 min 0
S5.12 SOLID FUEL BOILER PRO-
TECTION TEMP. Setting of solid fuel boiler protection temperature. If this temperatu-
re is exceeded, controller gradually starts to increase calculated
stand-pipe temperature in circuit 1 and 2. 70 ÷ 90 °C 77
S5.13 MAX. SOLID FUEL BOILER
OR HEAT ACCUMULATOR
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

S4.10 REQ. D. H. W. TEMP. BY
WARMING WITH COL-
LECTORS OR SOLID
FUEL BOILER With this setting is set requested d. h. w. temperature if it is being
warmed with solid fuel boiler or solar collectors. 50 ÷ 90 °C 70
S4.11 MIN. AMBIENT TEMP.
FOR D. H. W. HEAT PUMP D. h. w. is warmed only with heat pump if ambient temperature is
above the set point temperature . D. h. w. warming from central
heating system will activate when the ambient temperature drops
bellow set-point temperature. Set parameter S1.4=10 (for sensor
T1) or S1.5=11 (for sensor T8) to activate this function.
5 ÷ 30 °C

S4.12 D. H.W. WARMING PUMP
SWITCH-OFF DELAY Setting of d. h. water warming pump switch-off delay after d. h. w.
was warmed.
0 ÷ 10 min 5
