HOLIDAY PROGRAM - This is a single program that repeats day after day until you turn it off. It
supersedes the weekly program. To modify it touch PROGRAM on the MANUAL screen. It uses the
Calendar method for programming (see pg7 ).
VACATION - This function will hold a pre-set temperature until you turn it off. The preset is saved for
next time.
FRESH AIR -
If you have a fresh air baffle connected to the EX terminal, the LS-90 will use this
outside air source as the 1st stage of heating or cooling. Useful in desert climates where outside air
temp can change very quickly or just to freshen indoor air quality.
EMER HEAT - This is available if you have a HEAT PUMP with auxiliary heat. When you select this
your HEAT PUMP is disabled and auxiliary heat is your sole source of heat. This manual override
setting stays active until you turn it off. (This command is not displayed if you do not have a heat
pump). Remember auxiliary heat is more expensive than the heat pump.
Auto Run the pre-set program
The
LS-90 comes pre-programmed with an Energy-Star
TM
approved program. This program is
recommended by the EPA for energy efficiency. We strongly recommend that you Auto-Run this
program for one week, and see if it works for you. If it does not fit your needs you can always input a
custom program.
• To Auto-Run the Energy-StarTM program, press and select HEAT or COOL with the mode
selection. Set the time and Day and Press HOME. The unit is now running the Energy-Star
TM
program.
