Blower and Motor - the unit incorporates only specially
designed and tested EC motors, allowing the blower
wheel to provide optimum performance in airflow-
efficiency and quiet operation.
Filters - washable, easy-to-remove, fine mesh air filters
are standard to all high-wall models. Tabs located on the
front of the unit can be unsnapped, allowing the filter
to be easily slid downward and removed. No tools are
required, nor any dismantling of the equipment.
Air Grille Distribution ~ all units are equipped with both
deflector blades and independent directional vanes,
enabling the supply air to be automatically distributed,
and air flow and direction to be customized.
Electro-Mechanical Controls allow operation with 24 VAC
thermostat. When any of the motor speed terminals is
powered ON or Modulating signal is more than 2.0 VDC,
the stepping motor is working and opens the louver
at the maximum position. When all of motor speed
terminals are powered OFF or the modulating valve
is less than 2.0 VDC, the stepping motor will close the
louver. The condensate pump will run continuously, as
long as coil temperature is less than 59°F (15°C). Alarm
notification and zone control functions are available. A 40
VA 24VAC transformer is equipped with the unit, which
is used to supply 24VAC power to the thermostat and
modulating valve.
