## Questions & Answers

**Q: Can this be controlled by smartphone**
A: Hi Andrew, unfortunately i don't know if it is controllable by your smartphone but if you Google search the whole part number you will see the user instruction manual on the Danfoss site and hopefully that will answer your query. Alternatively, if you phone Danfoss technical sales helpline they will be able to assist. Regards James

**Q: is this compatible/replaceable with Danfoss cet2000b-rf hot water cylinder thermostat?**
A: I think that's the one I had that I bought this to replace, that one is discontinued I believe. I had to replace both components for it to work, noth the thermostat and the remote part but none of this required an electrician. I just removed the old fronts and switched them for this one and it worked. No wiring involved just replacing the fascias essentially
