I have my Nest learning thermostat scheduled to change from an overnight temp of 62 to a morning temp of 74 beginning at 5:30am so that the house is warm by 7;30am. I've noticed that the house isn't close to the 74 degree temp setting, even after 7:30am. I have the "True Radiant" setting turned on with a maximum preheating time at 2 hours. Eventually (after a few hours) the 12'x14' room will get to the proper temperature, but it's far more than the 2 hours I have programmed it for. Everything seems to be working fine on the actual thermostat (i.e. - I can communicate effectively with the Nest thermostat via my iOS app and physically on the thermostat itself, so it appears that everything was set up properly). Can anyone help me understand why my heat doesn't seem to be getting to the temperature settings at the time that I've programmed my Nest thermostat to warm to? Thx, EBnMN
