Grasslen FM 24 Hour timer.
24 Hour 120V timer for your hot tubs mechanical control system.
When replacing your old hot tub timer with a new one, ensure the new one is of the same volts as the old one, as they are available in 120V 240V.
These hot tub timers were used in older mechanical hot tub control systems before the newer electronic system came out. They are used to set the hot tubs filtration cycle manually and run on a 24 hour cycle.
If you have an older hot tub that uses one of the hot tub timers it's a great idea to set the hot tubs filters cycles to off peak times to save on energy cost.
