11. OPERATION OF THE CONTROL UNIT
The control unit, mounted either on a wall or box 503, is made up of two sliding switches and one control knob. The
sliding switch on the left, allows for the modification of the flow between the room and the outside from a maximum
of Qmax to a minimum of Qmin. Besides placing the sliding switch on the left in the OFF position, you get a system
shutdown.
The sliding switch on the right provides for three modes of operation:
• Auto: changes the flow from extraction to collection of air;
• In: air collection only;
• Out: air extraction only.
The adjustment knob allows for the variation of the duration of cycles of air collection/extraction, from a minimum
of 35 seconds to a maximum of 200 seconds depending on the temperature ΔT difference between the exterior and
the interior.
If the difference in temperature ΔT between the room and the exterior is raised, in order to guarantee the thermal
output, the time cycle must be the shortest possible (35 seconds). If instead the difference in temperature ΔT is close
to zero, the cycle must last as long as possible (200 seconds).
If for example in winter the exterior temperature is -15°C and thus the difference in temperature ΔT between the
interior and the exterior is raised, turn the knob to position (1). Unlike a day in spring, where the difference in
temperature ΔT is minimal or close to zero, turn the knob to position (2) (Figure 14).
