Line voltage usually controls the timer functions when properly wired until a power outage occurs; then battery power takes over until utility power is restored. Should utility power be off for an extended period of time, eventually the battery will drain completely
Double check to make sure you wired your wall switch timer properly.
Make sure there are no loose wiring connections.
Even though you purchased a new replacement timer wall switch, it could be a manufacturer's defect.
Has your home electrical system experienced any signal spikes? Electronic components are very sensitive to impulse spikes/surges and can be damaged very easily.
If you are experiencing surges or spikes, perhaps investing in a whole house surge protection system (Intermatic IG series) would be the way to go as well. It'll protect all your electronic devices and appliances through-out the house.

that should work no problem , but do make sure its only a gfci model not a combo acfi/gfci as with a mechanical timer the acfi is gonna misinterpret the switch closure and shut the power off

ohh and do remember just because the timer is rated at 40 amps and your feeding it with a 20 amp gfci doesn't mean it will work too 40 amps !!

Try connecting a lamp (correct voltage, etc) directly to the transformer. Most likely, the wire from the transformer to your lights is broken... The reset button can't reset anything, if there's nothing wrong there.

both are timers and the possible difference is the current rating for the unit
the rating for the heater may be higher so be careful in that aspect
talk with an accredited electrician for exacting advice

Open following link to see clear drawing and instructions for wiring ST01C timer.
Page also has EZ programming steps:

Red wire is capped.
Blue wire goes to Load (wire to sconces)
Black wire connects to Line wire (wire from breaker)
Green wire goes to ground.
If you are uncertain about Load and Line wires, just connect them either way, turn power ON, push on-off button, it lights don't come on, then reverse wires.
I have tested this timer, and information here is correct.
Don't forget to install CR2 battery, otherwise display will not show.

The timer may be working, but the switch has failed. This is a common failure of electro-mechanical timers.
