PROGRAMMABLE
VERSION
The additional heater operates
completely independently of engine
operation and allows the following:
heating the passenger compartment
with the engine off
defrosting the windows;
heat the engine coolant and then the
engine itself prior to starting.
The system consists of:
a diesel burner for heating the water
with an exhaust silencer for the
combustion gases;
a metering pump connected to the
reservoir pipes for supplying the burner;
a heat exchanger connected to the
engine cooling system pipes;
a control unit connected to the
passenger compartment heating/
ventilation system to allow automatic
operation;
an electronic control unit for
controlling and adjusting the built-in
burner;
a digital timer fig. 76 for turning the
heater on manually or for programming
its turn-on time.IMPORTANT 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.
