After heater activation, whether
programmed or manually, the
electronic control unit operates the
coolant pump and turns on the burner
in accordance with pre-set, controlled
procedures.
The circulation pump output is also
controlled by the electronic control unit
in order to minimise the initial heating
time.
When the system operates, the
control unit turns on the passenger
compartment heater unit fan at the
second speed.
The thermal power of the boiler
is regulated automatically by the
electronic control unit depending on
the temperature of the engine coolant.
The heater can turn off spontaneously
due to misfiring after start-up or
because the flame goes out during
operation. In this case, carry out the
turning off procedure and try to turn the
heater back on. If it still does not work,
consult a Fiat Dealership.
WARNING The heater is equipped
with a thermal limiter that cuts off
combustion in the case of overheating
due to insufficient coolant/coolant
leaks. In this case, after repairing the
fault in the cooling system and/or
topping up the fluid, press the program
selection button before turning the
heater back on.
Activation of the heating system
When an automatic climate control
system is present, the control unit sets
the air temperature and distribution
when the heater is turned on from
the park position. When a manual
heater/climate control is present, to
obtain maximum heater efficiency,
check that the passenger compartment
heating/ventilation temperature
adjustment knob is in the 'hot air'
position.
To prioritise passenger compartment
pre-heating, set the air distribution
knob to the position.
To favour windscreen demisting, set
the air distribution knob to the
position.
To obtain both functions, set the air
distribution knob to the position.
