Adjustment of fan for low effect level
The adjustment range for the low effect level is approx. 155-190 V measured
with a ”true RMS” voltmeter.
•
Put the switch in position 6, 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.
Adjustment of boiler temperature
(shut-off temperature)
•
Put the switch in position 5, the operating switch in position
on
and press the
test button. The number of diodes, which are illuminated, is proportional to
the position of the boiler temperature potentiometer, which corresponds to
approx. 55-85
o
C.
Adjustment of dT
”delta t”
(temperature distance between start and stop in the burner programme)
•
To change dT, shut off the operatig switch on the control box. Turn the
switch to desired dT (0, 1, 2, 3). Switch on the operating switch.
Changing dT 10
°
to 15
°
, 20
°
or 25
°
(from level 0 to 1, 2 or 3 on the switch) increases the
distance between start and stop by 5
°
for each value. The boiler’s preset end temperature (the
boiler temperature) does not change.
