Service Hours

Service Hours (Pro) counts your heater's running time, recorded on this phone while it's connected.

• Heating time: time with a steady flame.
• Starts and failed starts: a failed start is a run that never reached steady heating.
• Since last service: hours since you last tapped Mark as serviced today.
• Recent runs: how long each one took to light, how long it heated, its lowest battery voltage and its estimated energy (est. Wh and Ah; see Heat Graph and energy).

Time while the phone wasn't connected can't be counted, and the app tells you when part of a run was missed.

Your heater's manual has its service schedule.

Same help as in the app (More → How to use).
