Ultimate Timer User Manual

What this software does

Ultimate Timer is a programmable timer with two operating modes:

Cyclic Timer: repeats ON and OFF periods for a fixed number of cycles or forever.
24h Timer: follows a 24-hour schedule built from 15-minute blocks.

You can use it from the local TFT display with the rotary encoder, or from a web browser when WiFi is available.

Important behavior to know

Profiles: cyclic profiles are stored normally, while 24h profiles use an automatic -24h suffix.
Default profiles: default and default-24h are always available and cannot be deleted.
Auto Save Profile = No: timer-setting changes affect the running timer immediately, but you must use Save Profile to keep them permanently.
24h timer: start/stop/reset buttons are hidden because the schedule follows wall clock time automatically.
Warp Speed: only affects cyclic timers, resets to Disabled after every restart, and accelerates 60x (remaining active across both phases when either cyclic unit uses minutes).
