So I was excited to see I could make a routine for my Ecobee3 whereby I could chose the heat source for the specific time of day. Long story but I wanted to use my Aux heat (NG) during times of high electricity costs (TOU).
Unfortunately the allotted time frame I gave it lapsed and the Thermostat stayed on Aux. I then tried to create a second routine to turn the command back over to the Ecobee but there was no option for regular heat, Heat pump in my case.
