Programming 3 zone thermostat
I have a multi level home, and it's set up in 3 zones so I can set my thermostat for each zone, up to 4 periods per day, for the whole week(HVAC tech says they now claim this method really doesn't save $). We are comfy at 68 for heat, so if other zones aren't being used for a period, what is the lowest I can set them without causing a problem? Is it efficient to have different temps set for each zone? Will it harm the system? Or should we keep all zones and periods set at 68?
Once summer hits, what should we do there? Our comfort level set for air conditioning to go on after room hits 77 or higher. But some days we are not in the house all day and summer is different than winter, in winter, I would not want to turn the heat totally off, in summer though, is it necessary to run AC if we're not even home?
Some people play with thermostats all the time, up, down, etc, while others claim setting ot and leaving it constant.
