This will unlock the 9000 Press copy then nest then hold then energy usage. This locks and unlocks tstat.Russ
I dont recognize any button you listed except the hold. The thermostat has a dial on the left side that is for programming. turning it you can set weekend programming and weekday programming. right side has slide that sas heat, off, cool. Middle slide says auto and on for fan.
try this for a model number Psph521
the model number may be: Psph521
Got it . Push next next next hold It should unlock. Russ
Thanks I will try this.
