OPERATING YOUR ELECTRIC AmR CONDITmONER

temperature at the level you select. Most themaostats have 3
controls: a temperature control selector, a FAN control, and a
SYSTEM or MODE control. RefEr to your thermostat owner's

run in cooling mode until the indoor temperatore is lowered to the

level you have selected. On extlemely hot days, your system will

run for longer periods at a time and have shorter "oft" periods than

on moderate days.
