! EBERSPÄCHER HEATER
Switching on
The indicator lamp in the control panel lights on start-up.
The glow pin is switched on and the fan starts to turn
slowly.
!Monitor this!
The fan comes on by itself at first (cold air) if there is too
much residual heat from a previous heating operation
in the heat exchanger. Once the residual heat has been
eliminated start-up commences.
Airtronic start-up
The fuel starts to flow after about 60
seconds and the air-fuel mix is ignited
in the combustion chamber.
Once the combination sensor (flame
sensor) has recognised the flame, the
glow pin will be switched off after
about 60 seconds.
The heater will reach the «POWER» setting after another
couple of minutes (amount of maximum fuel and maximum
fan speed)
.
Selecting the temperature on the control panel
The inside temperature is pre-set using the rotary
adjustment knob to between +10°C and +30°C depending
on the heater selected, the area to be heated and the
outside temperature.
The setting chosen is an experimental value.
Adjustment when heater is in service
The temperature of the space, even of the suctioned hot
air, is monitored constantly when the heater is in service.
Adjustment commences when the temperature is higher
than set on the control knob. Four adjustment levels are
provided so that the heat current may be adjusted to
match precisely the heat delivery required.
The fan speed and fuel quantity correspond to the
respective adjustment levels. If the adjusted temperature
is still exceeded when the equipment is on its lowest
setting, the heater will move to the «STOP» setting. The
fan will operate by inertia for about four minutes as part
of the cooling process. The fan will then continue to
operate at minimum speed (circulation of air) or even
switched off (cold air) until switched on again.
