Excellent Temperature Switch
Used this switch to automatically turn on heat trace for freeze protection on well pump piping and tank. Worked as designed.

TH-5-20
Best thermostats that I have used in greenhouse and high tunnels. Can’t go wrong with these. It’s actually a TH-5-20.

Works Well, but be aware of how it operates
Takes a bit of tweaking to get the system working as desired. Be aware that this unit will run heating AND cooling units, but it will switch back and forth at the designated temp in an attempt to keep the temperature right where you want it without a "swing range." Bought a second one so I could have a range between heat and vent in my greenhouse - one set to activate the heater if too cold, the other runs the vent fans when too warm. Good solid unit so far.

Perfectly Accurate and Dependable
Sure, you can buy a cheap Chinese plug in temperature control but they are faulty and unreliable.This one, I wired to be able to plug it in wherever needed.It is 100% accurate and dependable for heat or air conditioner. Don't waste money on junk, buy this one and you will know that it's always working properly.
