I bought this unit to replace a brand new Honeywell unit. the Honeywell unit could not adjust span and held temperature to 1 degree at a very high cost. this unit is tedious to program but not difficult. the span is set able a few degrees which allows the unit to NOT short cycle and holds temperature to your programming. this also cut a/c cost! wish I bought this one before the Honeywell, I could have saved 100+ dollars on the electric bill.
