1. Use a test thermometer to read the current room temperature.
2. Place a screwdriver in the center of the thermometer assembly (Figure 6). Carefully
rotate thermometer assembly until pointer tip indicates the correct room
temperature.
N N N N O O O O T T T T E E E E : : : : Avoid breathing on or touching the bimetal spiral since this affects the
temperature reading.
Thermostat limit stops define the
minimum and maximum thermostat set
points. The limit stops engage in the set
point cam gear teeth and cause
interference between the set point cam
gear and the adjustment knob gear.
To change limit stop settings, use needle
nose pliers to pull limit stop between the
set point cam gear teeth. Rotate limit
stop to its new position. Do not pull limit
stop any more than necessary to clear
the gear teeth. Changing the limit stop
position one gear tooth changes the limit
stop setting by 1-1/3°F (0.7°C).
