## Questions & Answers

**Q: What batteries does it take?**
A: Model I have is hard wired - so no batteries.

**Q: How to pair to relay box**
A: It's basically a straight replacement for your existing thermostat.  If you don't have an existing thermostat and are trying to do this yourself then the answer depends on your relay box / programmer etc.

**Q: How to hard wire neutral live and N/O**
A: Sorry but it was fitted by our plumber who was here servicing our boiler!

**Q: If you programme it to 20 is that actually the right setting**
A: Yes. The thermostat will prompt the boiler to fire until the desired set temperature is reached and the moon cycle to maintain that temperature.  What is changeable is the number of potential firing cycles in a given period of time.
The instructions and explanations provided are quite comprehensive.
