(applies to COMPACT Heat only)
The COMPACT Heat can be used for heating the room.
When HEATING is activated, the electric air heater (7.5
kW) heats up the air. A change-over damper in the lower
section of the air handling unit is reset and the air is led to
the air discharge outlets at the bottom of the unit. The air
is discharged at high velocity and follows the floor surface
by means of the so-called coanda effect. This enables long
throw lengths and quickly heats the entire premises.

The damper in the air recirculation section is reset and
room air is circulated. The louvre damper for exhaust air
closes to prevent any cold down draught.
The electric air heater (7.5 kW) heats up the air. A change-
over damper in the lower section of the air handling unit
is reset and the air is led to the air discharge outlets at the
bottom of the unit. The air is discharged at high velocity
and follows the floor surface by means of the so-called
coanda effect. This enables long throw lengths and quickly
heats the entire premises.
