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.
