7.5 SUPERHEAT OFFSET DIP SWITCH SETTINGS

7.6 EXV STEP DIP SWITCH
The EXV dip switch has an optional 500 or 1600 steps setting. This dipswitch should
currently be in the 500 step position only. Rheem does not currently supply 1600 step
EXV's. The dipswitch makes the control forward compatible with a 1600 step EXV for
possible future use.
