Turning the Air Conditioner OFF

Change the thermostat's system mode to OFF and the fan
mode to AUTO (See Figure 1). NOTE: The system will not
operate, regardless of the temperature selector setting.

Operating the Indoor Blower Continuously

circulate the indoor air to equalize a temperature unbalance
due to a sun load, cooking, or fi replace operation.
Set the thermostat fan mode to ON (Figure 1). The indoor
blower starts immediately, and will run continually until the
fan mode is reset to AUTO.
The continuous indoor blower operation can be obtained
with the thermostat system mode set in any position,
including OFF.
