Changeover Moduline Heating/Cooling — Both hot air and
cold air distribution are possible with a Moduline system.
The Moduline unit uses a director diffuser which, sensing
the duct temperature of the supply air, directs the air towards
or away from the perimeter wall. (Fig. 7.)
The Moduline location for heating and cooling requires
the unit to be a specific distance from the outside wall in
order to produce satisfactory distribution of the hot air. The
recommended location is shown in Fig. 8.
HEATING
With hot air in the duct, all discharge air is directed towards the
perimeter wall to offset the transmission.
COOLING
With cold air in the duct, the discharge is two-way blow — both into
the room and towards the wall.
