Circulation mode
In this operating mode, only the air supply fan runs and
the unit can be used to circulate air.
Thermostat regulation and heating operation are not
possible.
1. Set the operating switch on the control box to
“
II
” (= ventilate).
The burner doesn’t start
1. Open the shut-off valve on the oil filter.
2. Check the oil filter for dirt.
3. Make sure that the fuel tank has an adequate
amount of fuel.
4. Check the heating oil for paraffin accumulation.
Paraffin can build up at temperatures as low as 5 °C!
5. Check the oil lines for damage.
There is a danger that there are air bubbles in the
lines
.
6. Check whether the safety temperature limiter (STB)
was triggered.
This could be caused by the following:
- The unit was not able to cool down because the
power supply was interrupted.
- The air outlet temperature is too high because air
is not being directed properly.
- Air cannot flow freely in and out.
7. Prior to a STB reset, you must analyse the causes
and fix this problem.
8. Check that the temperature monitor (TW) is function-
ing properly using appropriate means.
9. Check the sensors and the capillary pipes of the
three-speed combination regulator for damage and
dirt.
See “Safety Mechanisms” chapter.
10.
Check whether the “Burner” malfunction light is lit up.
If so, release the burner by pressing the “Burner Re-
set” button on the control box.
The burner tries to start.
Shutting Down the Unit
1. Set the operating switch on the control box to
“0” (off).
2. Shut off the fuel supply.
Important information about the cool-down phase
of the unit.
The air supply fan continues to run to cool the combus-
tion chamber and the heat-exchanger and switches off
at a later time.
The fan can be run several times until the unit is finally
switched off.
*
Never interrupt the power supply (except in emer-
gencies) before the cool-down phase is complete.
We assume no liability for damage to the unit by
overheating.
Troubleshooting
The unit doesn’t start
1. Check the power connection and the power fuses.
2. Set the operating switch to “
I
”.
3. Make sure the plug of the room thermostat is posi-
tioned properly.
4. Check the setting of the room thermostat.
The set temperature must be higher than the current
room temperature
.
5. Check the fuses F1 and F6 in the control box.
6. Check whether the safety temperature limiter was
triggered. In this case, release it by pressing the
“Overheating Reset” button on the control box.
7. Prior to a STB reset, you must analyse the causes
and fix this problem.
8. Set the operating switch to “
II
” (ventilating).
If the air supply fan now starts, look for the problem
with the burner
.
The air supply fan does not start
1. Check whether the “Fan” malfunction light is lit up. If
so, to press the “Fan Reset” button on the control
box.
2. Check the fuses F1 to F3 in the control box.
3. Check the control fuse F6 in the control box.
4. Check the electrical cord to the fan for damage.
5. Check that the temperature regulator (TR) is func-
tioning properly with appropriate means.
*
Repair and maintenance work on the burner or
electrical installations may only be performed by
authorised personnel for safety reasons.
