## Questions & Answers

**Q: I’m getting it for my cat’s 5” cube fountain, can i get the 30w one for the dry run feature? or i should go with the 10w for the tiny fountain**
A: this is a heater
it's about 3" in length 
and you can monitor the temp which sits outside of the container

**Q: What is the diameter of this heater?**
A: The diameter is 2cm (0.8").

**Q: My heater is displaying “ 8,8,8 and when I click the button nothing happens, how do I fix this?**
A: Well, that's a tough one.  The error codes are like E1, E2 etc.  so its not that.  Assuming the device is under water, and electricity is flowing to the heater, the only thing I would try is unpluging it, wait a minute or two and plug it back in.  Sorry I could not help more.

**Q: Does it turn off once it reaches the temp the user sets it at?**
A: You can see the temperature displayed at all time. It is maintained at the set temperature.
