6.1. AIR DISTRIBUTION WITH
MOTORISED CIRCULAR SHUTTER
The heat pump airflow can be controlled
by means of a motorised shutter, offering
90° adjuststment from completely open
(fig.A) to completely closed (fig.B). The
valves are activated electrically, using
a servocontrol with spring return. Shutter
operation is linked to the fan status, in
accordance with the following principle:
while the HP is in standby (fan off), the
shutter is not powered and therefore the
spring return guarantees the completely
open position (fig.A);
- while the HP is running (fan on) the
shutter is powered and therefore in the
completely closed position (fig.B).
