## Questions & Answers

**Q: Can the sensor be submerged in a water tank to read water temperature?**
A: I sealed the sensor at the end of the wire inside a 4-inch length of heat-shrink tubing and sealed the ends with silicone.  I use mine to turn a heating element on/off during the winter to keep a small livestock water tank from freezing.

**Q: can the sensor wires be lengthened**
A: Simple answers: It uses an 10K NTC sensor that can be lengthened up to 100 feet with 18 gauge (AWG) SHIELDED wire. Up to 10 feet non-shielded.

**Q: Can you turn it on and off?**
A: Yes. You can turn it on and off. Press the button "Rst" to turn it on/off.

**Q: How do I switch between cold and hot mode**
A: Just change the HC value. HC=H for Heating Mode. HC=C for Cooling Mode
1.Press SET for 3 secs, HC appears on screen, release SET button
2.Press SET once to enter HC parameter
3.Press UP/DOWN button to select C or H, Press SET once again and back to HC(main menu)
