INSTALLATION INSTRUCTIONS
(continued)
TEMPERATURE LIMITING
The normal range of the thermostat control is
approximately 60°F. to 85°F. The control range
may be narrowed by the use of the temperature
limiting screws located behind the control panel.
Repositioning the screw on the left will limit the
maximum temperature about 3°F. for each hole
in a clockwise rotation; the screw on the right will
limit the minimum temperature when moved
counterclockwise. Limiting the maximum and
minimum settings prevents users from turning the
controls to extreme positions. Restrictions to full
rotation of the thermostat knob may require
explanation to the room occupant that unit will
provide comfortable conditions at settings allowed.
To access the limiting screws, remove the room
cabinet, remove the Thermostat knob and the
Operation knob by pulling each knob off its shaft
and removing the control panel. Set the limiters to
the desired setting, replace the control panel and
the control knobs. If the original settings do not
allow sufficient room temperature control the
limiter screws may have to be repositioned.
If the temperature limiters are used it is
recommended that the limiters be set no higher
than the second hole from the original bottom
position. This provides an operating range
between approximately 66°F. and 79°F. In order
to maximize the benefit of the temperature
limiting it may be necessary to adjust the limiter
screws seasonally to allow unoccupied rooms to
be maintained at moderate temperatures (i.e.,
heating season temperatures limited between
60°F. and 75°F.; cooling season temperatures
limited between 85°F. and 65°F.).
AIR LOUVERS
To change the louver direction, remove the room
cabinet and 2 louver screws that hold the louvers
in place. Turn the louver section 180° (end for
end), replace the screws and replace the room
cabinet. The textured face of the louver section
must be toward the room side.
NOTE: For high-mounted Zonelines where greater
room cabinet louver adjustments are required,
order the RAF45 Room Cabinet.
The direction of the heated or cooled air may be adjusted by
removing and turning the louvers around.
