I know this probably isn't as difficult as I'm making it out to be, but I'm having a hard time understanding the Auto setting on my Honeywell TH5220D thermostat.
When the system is on Auto, do the heat and cool temeratures tell the system when to kick on and off? I'm trying to keep my house at 67. What would I need to set the heat and cool settings at to keep it at or as close to 67 as possible? Right now I have the cool setting on 69 and the heat setting on 66. Is that what I should have it on? The manual mentions a 3 degree deadband and won't let them go any closer together than that.
Thanks for any info.
