Control box adjustments
Turn the function switch to desired position – turn on the operating switch –
press the test button. (Green diode
on
flashes, red diode
Larm/Test
is
illuminated during the test interval and a number of green diode on the display
are switched on).
All settings, except dT, can be changed during operation (without support by
indications from the LED’s).
Specified voltage values are for 230 V supply and by use of a ” true RMS-
voltmeter”. Less qualified voltmeters can show deviations of several tens of
volts measuring triac-regulated voltage.
Adjustment of fuel quantity during operation
•
Put the switch in position 8, the operating switch in position
on
and press the
test button. The screw motor starts and runs the operational portion during 6
minutes, meanwhile the red diode (Larm/Test) is illuminated and the set
value will be shown on the display with the number of illuminated diodes.
Set the potentiometer at desired operational portion, the number of
illuminated diodes will follow the setting. Put the operating switch in
position
off
when the adjustment is finished.
Adjustment of fuel quantity at start
•
Put the switch in position 9, the operating switch in position
on
and press the
test button. The screw motor starts and runs a start portion, the red diode
(Larm/Test) is illuminated and the set value is shown on the display with the
number of illuminated diodes. Set the potentiometer at desired start portion,
the number of illuminated diodes will follow the setting. Put the operating
switch in position
off
when the adjustment is finished.
Adjustment of fan for high effect level
The adjustment range for the high effect level is approx. 175-230 V measured
with a ”true RMS” voltmeter at the fan connections.
•
Put the switch in position 7, the operating switch in position
on
and press the
test button. The screw motor starts and runs a start portion, the red diode
(Larm/Test) is illuminated and the set value is shown on the display with the
number of illuminated diodes. Set the potentiometer at desired fan speed, the
number of illuminated diodes will follow the setting. Put the operating switch
in position
off
when the adjustment is finished.
