ON: To manually turn ON the fan, touch the FAN icon and then touch ON.
The FAN icon will begin turning and the fan will run continuously until switched to AUTO. Fan ON
function is available in OFF mode to allow simple ventilating.
POWER BUTTON and MODE selection
The power button brings up your mode selection options: COOL HEAT AUTO OFF
COOL - This will operate the cooling portion of your HVAC system until it is turned off.
HEAT - This will operate the heating portion of your HVAC system until it is turned off.
AUTO - The
LS-90 TRUE AUTO mode switches automatically between heat and cool throughout
the year. Unlike other manufacturers, the
LS-90 TRUE AUTO has no temperature or time limitations
(Patent pending), just program your desired HEAT and COOL temps and select the AUTO mode. The
LS-90
will switch from HEAT to COOL as needed.
OFF- This takes your HVAC system “off-line” and it will not control HVAC functions. In this mode your
house may experience extreme heat or cold.
The HVAC STATUS indicator shows what HVAC function is active. It glows orange when the HEAT
function is active, blue when the COOL function is active, and green when the fan is
active. These indicators can combine, where orange-green indicates HEAT-FAN and
BLUE-GREEN indicates COOL-FAN.
RESET button - The RESET button re-boots the
LS-90 processor. It does not effect the user
programs that have been stored in permanent memory.
