Hi I'm Wayne

I will help you with this

the LP is a low pressure warning

the unit is low on freon,

you can not clear this code until the freon is

brought back up to Spec.

but for the future press and hold the down arrow and the equal sign (=)

at the same time, the screen will change to all modes

when you get to the code LP, the press the (=) sign again

that will clear it

Hi I said that wrong for the codes

to be seen and erased

Press and release the Select key to display the current alarm code on screen. If there is more than one active alarm, all the alarm codes on the unit can be viewed in sequence by pressing and releasing the Select key

then to remove press the equal sign
