## Questions & Answers

**Q: What is the hexagonal part in the middle of the body that has a hole in the middle for?**
A: I holds the cylinder stat together. You need to undo this rand remove the front to wire it

**Q: Can it be fitted in a bathroom on pipe work**
A: This is a thermostat for an immersion tank so, NO.

**Q: Your text says it is suitable for foam lagged tanks but how does it measure the temperature?**
A: You would have a hole in the lagging just big enough to fit the unit and the sensor on the back of the thermostat would measure the temperature.

**Q: Is the thermostat a simple on/off switch for a wired connection?  The description says it has WiFi connectivity.**
A: Yes
