temperature sensor bias is used to adjust the room air

temperature reading when in heating mode. (Not

normally required.)

Indoor Temperature Display:

Change between showing setpoint only on the display

during heating and cooling modes “SP” or displaying

“AA”. “SP” mode is the default mode.

S

If “SP” is selected, only the setpoint will be

displayed during heating and cooling modes,

regardless of what the real temperature is in

the room.

S

If “AA” mode is selected, the room

temperature will be displayed during heating,

cooling and fan only modes.

— If the mode button has been changed to

either heating or cooling modes, setpoint

the unit is off) and the last mode was
either cooling or heating mode, the
setpoint will be displayed for 10 seconds
before displaying room temperature.

— During heating and cooling modes, if

either the up or down setpoint key is
depressed, the display will show the
setpoint until 10 seconds after the last up
