OPERATING YOUR ELECTRIC AmR CONDITmONER

controls: a temperature control selector, a FAN control, and a
SYSTEM or MODE control. RefEr to your thermostat owner's
manual for more infbrmation.

sela'ice calls, familiarize yourself with the %llowing g_cts:

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.
