Pushbutton functions
The AFA4000/2 has 3 programmable pushbuttons. The pushbutton Icon is displayed on
the screen, above the relevant pushbutton. The pushbuttons are identified as Pushbutton
I, Pushbutton II and Pushbutton III.
Each Pushbutton has a Power Up Memory function. The Power Up Memory function sets
the pushbutton back to its last status, following a power fail cycle. For example, when the
Fan is On during a power failure, the AFA4000/2 powers up with the Fan pushbutton set
to On.
The AFA4000/2 pushbuttons are typically set with Pushbutton I used for Fan On/Off and
Pushbutton II used for Lights On/Off.
