2.3.2 - POSITIONING OF THE JUMPERS (their purpose is to implement some functions necessary for the operation
fig. 11
JUMPERS ON THE DISPLAY PCB
JP4
: GAS TYPE SELECTION
Naturl gas
: Jumper on NAT (standard supply position)
Liquefied Petroleum Gas
: move jumper to LPG position
The standard supply position correspond to the gas type shown on all
the labels within the boiler
JP3
: EXTRNAL TEMPERATURE COMPENSATION FOR OUTER SENSOR
Boiler with outer temperature sensor: jumper on
J
Boiler without outer temperature sensor: jumper on
OFF
JP2
: SELECTION OF PUMP OPERATION MODE
If pump has to work continuously: jumper on
1
If pump has to stop after an overrun of 5 min since the stop of the heating
demande: jumper on pos.
2
(standard supply position)
JP1
: CHRONOSTAT FUNCTION
(do not change posion of the jumper)
This function is not yet available.
Jumper on
(Standard supply position: for a good working keep the jumper in
this position).

Relation between the temperature (°C) and the resistance (Ohm) of the heatin temp. sensor SR and the D.H.W. temp. sensor
SR. Example: At 25 °C the nominal resistance is 10067 Ohm - At 90 °C the resistance is 920 Ohm.
