You really don't need the resolution of a 10-bit result for this purpose.
Left justify the result and take the upper byte only.  This is the same as
using a regular 8-bit A/D.

Why do subtraction if you just want to match up a set point?  Just XOR the
setpoint bytes with the ADRES:

    movlw SetPointHI
    xorwf ADRESH
    btfss STATUS, Z
    goto No_Match
    movlw SetPointLO
    xorwf ADRESL
    btfss STATUS, Z
    goto No_Match
    .
    (otherwise, set point == ADRES)
    .
No_Match
    .
    .
    .
