Know before you buy
Yes, the TN311C is designed for both indoor and outdoor use. However, ensure it is plugged into a GFCI-protected outlet and positioned in a way that prevents water from pooling directly on the unit.
This model supports up to three on/off cycles per 24-hour period. It is a mechanical timer, so you set these cycles using the physical pins on the dial.
While it is built with heavy-duty construction, it is primarily designed for lighting and smaller appliances. Always check the wattage and amperage requirements of your specific device against the timer's maximum load specifications before connecting it.
No, this is a mechanical timer and does not include a battery backup. If the power goes out, the timer will stop, and you will need to manually reset the current time once power is restored.
It is very straightforward. You simply rotate the dial to the current time and push down the pins for the duration you want the device to be powered on.
