The problem I have with my heat pump programmable thermostat is that when it goes to step up the temp in the AM, it does so in a single 62 to 68 degree jump which brings on the elec heat (and my elec bill!!) I think they do this when there is a 2 degree or so diff between set temp and actual.
It should be easy with a microprocessor controlled stat to bring it up in staggered 1 degree jumps.
The manual for mine says it "Learns" how long it takes to come to the newly set temp and adjusts the time it comes on so you'r up to temp by the time you set but that still doesn't avoid the elec heat.
Anyone know of an even smarter stat??
