[QUOTE="ProDave, post: 266036, member: 6969"] A set back stat is just an admission from under floor heating suppliers, that under floor heating takes a long time to heat up. Sometimes too long in some installations, so a set back stat is just a bodge to keep the heating going, but at a lower setpoint, so it won't take so long to warm up. My own system doesn't have it. Yo just learn what the warm up times are for your system, and make allowances when setting your programmer. The system I was working on today goes one dafter. Not only does it have a set back stat, it also has an outside temperature probe so it can compensate for weather changes. WTF would it need to do that? it has a room stat for each zone so what more does it need? The owner wants me to remove the set back stat and outside temp. probe but I'm waiting on him getting another ordinary thermostat and to find the user manual (because you have to program the system to tell it what stat controls what etc) [/QUOTE]
