Commissioning
Operating sequence
The units can be used in the
respective operating modes for
air heating and air circulation
purposes (not ELT 3-2).
The units ELT 3-2 can be operated
exclusively in 2 heating stages
(2.2 or 3.2 kW).
They have a 3-stage operating
switch with the functions: Heat (I)
/ Off (0) / Heat (II).
The units ELT 10-6 and ELT 18-9
can be operated with three heating
settings and one fan setting.
They have a 5-stage operating
switch with the functions:
Off (0) / Fan (1) / Heat (2-4).
All units can be equipped with
a plug-in ready room thermostat
(accessory) to ensure that the
room temperature is constant.
Once the desired temperature
has been reached, the thermostat
switches the heating operation
off. If the room temperature falls
below the set temperature, the
thermostat starts up the heating
operation again.
!
CAUTION
After switching off the units
via the operating switch or
the room thermostats, the
supply air fan runs to cool the
heating resistors for a certain
time and then switches off
automatically.
NOTE
For optimum operation the
units should not be operated
above an ambient temperature
of 25 °C.
One person, who has been
adequately trained in the handling
of the units, should be tasked with
the operation and monitoring of
the units.
The units must be in the intended
horizontal position on their
supports at all times during
operation.
The units are equipped with the
following operating switches:

a separate feed point with
a residual current device in
accordance with VDE 0100,
Section 55.
CAUTION
Extensions to the connection
cable must only be conducted
by authorised specialist
electricians, taking into
consideration the unit capacity,
cable length and local use.
