4.2 TEMPERATURE SENSORS
AND WATER PRESSURE
TRANSDUCER
Tables 5 - 5/a show the resistance values
(
Ω
) that are obtained on the sensors as the
temperature varies and the transducer
when the pressure varies.
With the C.H. sensor (SM) interrupted
the boiler will not function with both
services. With the D.H.W. sensor (SB)
interrupted the boiler functions only
with heating.
Green led off
in case of no electricity
Red led flashing: in case of
insufficient water pressure (*)
Red led flashing: problem with C.H. sensor (SM)
Red led flashing: coil of the modulator stopped
Red led flashing: problem in flame detector circuit
Red led flashing:
