I had an issue with underfloor heating not working - everything had been fine before. I did my own troubleshooting and thought it must be the Wundersmart controller. I called the technical support team and they went through the issue methodically with me - one step at a time. It actually ended up being an issue with one of Honeywell heating valves and nothing to do with the Wundasmart unit. Even although this was the case, the technician made sure I exactly understood the issue. I went and bought a new valve and installed it - all works now. Thank you for a super service. These units have been flawless and we have a pretty big house and zones in every room. Great product.
