Initial operation
Initial operation of the unit and its forced-air burner must
be performed by the manufacturer or one of its author-
ised service representatives. During this process, all
regulating, control and safety mechanisms must be
checked to ensure that they are functioning properly and
set correctly.
à Oil and gas-fired units may only be put into initial op-
eration by authorised personnel.
à Make sure that the fan’s screws and bolts and
burner attachments are secure.
à Open the blow-out grille if necessary and adjust it as
required.
à Check the settings of the triple combination control.
à Switch the customer-supplied main switch or fuse on.
à Set the room thermostat to a higher value than the
current room temperature.
à Open the fuel supply and set the operating switch to
“Heizen” (heating).
If the oil burner was supplied by the manufacturer,
(up to VRS 50) the burner start is delayed as a result
of the standard oil preheating process.
à Adjust the throughput for the heating oil or gas to
meet the heating capacity of the unit.
See the unit’s type plate.
à Set the burner to the optimum values in accordance
with the manufacturer’s specifications.
à Measure the chimney draught when cold and hot.
à Keep a protocol of measurements and submit it to
the operator for safekeeping. Familiarise the opera-
tor with the system.
à Give the statement confirming the authorised com-
pany status and the company certificate of the re-
spective installation company to the relevant authori-
ties.
Important information about corrosion in the heat-
exchanger.
à The exhaust gas temperature difference may not
fall below 160 Kelvin.
This keeps the temperature from falling below the dew
point and prevents the resulting corrosion in the heat-
exchanger.
à If the unit is not set to its rated heat load or it is too
large for the necessary heat requirements, the
burner only runs in cyclical operation. Because the
required operating temperature is not reached in cy-
clical operation, more condensation accumulates
and there is more corrosion in the heat-exchanger.
Keep in mind that the air supply fan continues running
to cool down the heat-exchanger and can run several
times before the unit is finally switched off.
Unit Shut Down
Heating Mode
The unit runs fully automatically with the temperature
which has been pre-selected on the room thermostat.
Proceed as follows to put the unit into heating mode.
1. Turn the customer-supplied main switch or the fuse
on.
If the unit is taken out of operation for a
longer period of time, the customer-
supplied main switch or the fuse should
be switched off and the fuel supply
closed off.
3. Set the operating switch to
“Heizen” (heating) or “I”.
4. Adjust the room thermostat
to the room temperature
you want.
Ventilation
In this position only the supply air fan runs and the unit
can be used for air circulation.
Set the operating switch to “0”.
When heat is necessary, the forced-air burner switches
on automatically. The air supply fan only switches on
once the target temperature has been reached. This
prevents cold air from being blown out.
1. Set the operating switch to
“Lüften” (fan) or “II”.
2. Keep in mind that the unit’s
fan runs continuously.
It is not possible to control it
with a thermostat
G
Never interrupt (except in emergency situations)
the power supply until the cool-down phase is
completely finished.
Our guarantee does not cover damages caused to
the unit by overheating.
2. Open the fuel supply.
