Does the mat have a timer? Can I use an additional plug-in timer?

All mats have heavy duty analog timers with different settings, but It is a great idea to use an additional electronic plug-in one. First, you can set it to the exact minute. Also, if you use your mat for sleeping and do not want it to stay on all night, you can program your plug-in timer to shut it off after 1 or 2 hours. It will also protect you in case the controller’s timer fails.
