Ereada Purple Mini Mat Controller

The controller allows selecting seven levels of heat on the controller.   

Level 1 is 86°F or 30°C ( used for Negative Ions and Potential, all-night sleep low heat mode )  
Level 2 is 98°F or 36°C ( Low mode )  
Level 3 is 110°F or 43°C ( Low, medium mode )  
Level 4 is 120F or 49C ( Medium mode )  
Level 5 is 133°F or 56°C ( Medium-High mode )  
Level 6 is 145°F or 63°C ( High mode )  
Level 7 is 158°F or 70°C ( Highest mode )

• Red Light is activated by the Photon button for 1 hour every 4 hours, so during 8 hours, you have two cycles of 1 hour each. It is quite enough for stimulation. After one hour, the red light will switch itself off. In 4 hours, it will resume. In 1 more hour, it will switch off again.
• You can also manually deactivate the Photon function any time, and in this case, cycling will be interrupted. Or you can re-activate it, and the lights will be ON.
• Static magnets in the leg zone are always ON and work without electricity-generating the powerful 300 gauss intensity permanent magnetic field. Purple Mini mats have twelve static (permanent) magnets distributed throughout the mat. 
• Magnetic Field disappears with distance as per the reverse square law. The intensity goes down in direct proportion to the square of the distance from the coils. 
• Negative Ions are always generated by crystals and anion fabrics upon heat distortion. 
• The controller has a built-in eight hours auto-timer feature. It will stop heating when the time set is over.

You can use the mat in several modes all together or each separately:

If you are falling asleep, the best way to use it is to turn off the Photon function (so it does not wake you up when the Red Light resumes in 4 hours). But most important is to choose 1-2 low levels of FIR heat before going to bed. 

If you feel that 8 hours is too much, please use an external timer. A heavy-duty one with a built-in surge protector may be the right choice for double protection in the nighttime.
