## Questions & Answers

**Q: Do the btc 201 / btc 211 have battery backup or memory? if the power goes off, will they resume without me resetting it when power returns?**
A: We own the BTC211 and can definitely confirm that it has battery backup/memory.

**Q: Is there an option for a longer temperature probe cable, or a way to extend it?**
A: Seems like you could extend it easily as it is just a standard 3.5 mm connection. Though I have not tried it. This is an excellent reliable product!

**Q: What size screw do you use for mounting it to the wall? Must have a thin head**
A: Just try and find screws with a <1/4" diameter head and flat, good luck, they don't specify screws by head size. 
WTH these don't come with any hardware, IDK.

**Q: Does this Temp controller have solid-state relays or mechanical contacts?**
A: I'm sorry, I am not a technical person.  All I can tell you is - I set the parameters on the controller to keeps my greenhouse between 62 and 66 and it does all day and all night.  If the temperature goes above 66 the controller will not come on until it drops to 62.
