F3.7 SENSOR FOR
THERMOSTATIC
OPERATION
Selection of sensor for thermostatic operation.
1- T1 2- T2
3- T3 4- T4
5- T5 6- T6 4*
F3.8 THERMOSTAT
HYSTERESIS Hysteresis for thermostatic operation. 1 ÷ 30 °C 4
F3.9 AUXILIARY HEAT
SOURCE - DE-
LAYED ACTIVATION Selection if auxiliary heat source should activate immediately or with
delay if the collectors have trend and tendency to warm the water to
requested temperature. Delay time is considered as a time in which
the collectors should warm the water to requested temperature.
Auxiliary heat source will activate immediately if collectors don't have
trend and tendency to warm the water to requested temperature in
setted delayed activation time. 0- NO DELAY
1 ÷ 1440 min-
DELAY 0
F3.10 AUXILIARY HEAT

RATURE
Selection if auxiliary heat source should permanently heat the water
to min. temperature. 0- NO

F3.11 DIFFERENTIAL
THERMOSTAT
Selection if programmed output should operate as a differential
thermostat. 0- NO
1- YES
2- YES, INVERTED 0
F3.12 HEAT SOURCE
SENSOR FOR DIFF.
THERMOSTAT
Selection of heat source sensor (higher temperature) for differential
thermostat. 1- T1 5- T5
2- T2 6- T6
3- T3 7- T7
4- T4 3*
F3.13 HEAT SINK SEN-
SOR FOR DIFF.
THERMOSTAT
Selection of heat sink sensor (lower temperature) for differential
thermostat. 1- T1 5- T5

F3.16 CIRCULATION ON
OUTPUT
Selection if output should be used for hot water circulation and the
way it should operate.
1- circulation with pump running and standby time
2- circulation is activated with flow switch on terminal T3 and is
running for setted running time
3- circulation is activated with flow switch on terminal T4 and is
running for setted running time
4- circulation is activated with flow switch on terminal T5 and is
running for setted running time
5- circulation is activated with flow switch on terminal T6 and is
running for setted running time 0- NO
1- YES, RUN/
STANDBY TIME
2- YES, T3

F3.17 SWITCH-ON IMPUL-
SE / CIRCULATION
PUMP RUNNING
TIME
This function activates output for setted time. After setted time expi-
res, the output is switched off, regardless to other switch-on or switch
-off commands.
This setting is especially useful for control of support pump in Drain-
back systems.
Setting 0 means there is no delay and the output should activate
immedately and stay activated for the whole time of switch-on com-
mand.
