Heating
The appliances operate fully auto-
matically depending on the room
temperature.
1. Switch on the local main switch
or fuse(s).
2. Open the fuel supply.
3. Set the desired temperature on
the room thermostat.
3. Set the switch on the control
box to the „I“ or „Heat“
position.
It should be noted that the forced-
air burner starts immediately on
heat demand (except VRS 25 and
50), however the supply air fan
initially starts automatically when
the set temperature is reached.
This prevents cold air from being
blown out.
Set the switch on the control box
to the „0“ position.
The supply air fan continues to
operate to cool the heat exchanger
and can start several times up to
final switch off.
For extended periods of
non-use, the units
should be disconnected
from the power supply
and the fuel supply
shut-off.
Switching off
230V type
400V type
Ventilate
1. Set the switch on the control
box to the „II“ or „Ventilate“
position.
In this switch position, the supply
air fan runs continuously.
The appliances can be used for air
circulation or ventilation purposes.
Thermostatic control is not
possible.
■ The burner must be set to the
values specified by the manu-
facturer, however at least to the
values specified by the Federal
Immission Control Act.
■ A measuring report must be
prepared and handed to the
operator for safe keeping.
■ The operator must familiarise
himself with the operation of
the system.
■ The responsible authori-
ties must be provided with a
declaration from the specialist
company and certificate of the
installer.
Information on corrosion in
heat exchangers.
■
It must be ensured that the
exhaust fume temperature
difference of 180 Kelvin is not
reached.
This prevents the risk of cool-
ing below the dew point and
related corrosion in the heat
exchanger to a large extent.
AttENtION
The heater must never be
disconnected from the mains
supply via the main or emer-
gency switch before the cooling
down phase has ended (except
in emergency situations).
NOtE
If the heaters are not set to
their nominal heat load (see
rating plate) or are dimensi-
oned too large for the neces-
sary heat requirement, the bur-
ners operate in an intermittent
mode.
As the necessary operating
temperature of the heat ex-
changer cannot be reached in
intermittent operation, increa-
sed condensation unavoidably
occurs with the consequence
of higher corrosion in the heat
exchanger.
