    Hello,

    We have two 4T Hydron Module Units (1 combo unit, 1 split) that I feel are consuming more Kw than they should be.

    Speaking to one of the original contractors he suggested increasing the 2nd stage temperature differential (Honeywell Vision Pro 8000 stats) to allow for longer run times. I went through and increased both 2nd state temp differentials to 2.0 degrees (up from 1.0 degree). I wanted to get some opinions on this as well as the current settings on the t-stats.

    - system changeover: auto
    - auto changeover deadband: 3 degrees
    - finish w/ high cool stage: no
    - finish w/ high heat stage: no
    - cool stage differential stage 2: 2 degrees
    - comp heat differential stage 2: 2 degrees
    - backup head droop: 3 degrees
    - upstage timer for backup heat: off
    - compressor cycles per hour stage 1: 3
    - compressor cycles per hour stage 2: 3
    - backup heat cycles per hour: 9
    - compressor off time: 5 mins
    - extended fan run time in cool: off
    - extended fan run time in heat: off

    Thank you all in advanced!
