Figure 10
CAUTION: DO NOT TAMPER WITH THE HIGH
LIMIT SETTING.
There are two adjustable Fan Control Settings. They control
when the Convection Blower turns on, and when the Blower
turns off. This will help control the temperature of the air
coming out of the registers. These settings may be adjusted
to accommodate customer preference. If the air seems too
cool, simply adjust the Fan Off setting higher to shut the
blower down sooner. Factory settings are shown in figure 10.
The Fan limit has a Break-Away Tab that has been removed.
When replacing a Fan Limit Control, be sure to remove the
tab as shown in figure 10.
