For example, moving the left screw clockwise 4
positions over from Standard Position limits the
maximum heating set-point temperature to 29.4ºC – (4
x 1.4ºC) = 23.8ºC (85ºF – (4 x 2.5ºF) = 75ºF).
Similarly, moving the cooling set-point right screw
counter-clockwise 2 positions over from Standard
Position limits the minimum temperature to 18.3ºC +
(2 x 1.4ºC) = 21.1ºC (65ºF + (2 x 2.5ºF) = 70º F).
Therefore in this example roughly speaking, the end
user cannot heat the room to greater than 23.9°C (75ºF)
nor cool the room to less than 21.1°C (70ºF)
.Experimentation may be necessary to obtain a
desirable setting. Keep in mind that the actual
thermostat temperature sensing occurs at the sensing
bulb in the return air stream, sensing air being pulled in
through the bottom of the front panel near the floor.
NOTE : IF THE ROOM TEMPERATURE IS STILL
NOT SATISFACTORY AT THE COOLEST
THERMOSTAT SETTING, THEN COMPLETELY
REMOVE THE RIGHT HAND LIMITING STOP
SCREW.
Important:
Before reinstalling the knob, manually
turn the thermostat shaft so that the rib under the knob
will locate in between the stop screws once the knob is
installed. Failure to follow this step may cause an
unintended temperature range to arise.
