[The Atomic Ass]

Lately I've become interested in these. My current central controller is just a digital thermostat only, no program ability.

But I also see a marked difference between running my space heater, and running my central, to keep the the temperature comfortable while above freezing. I use WAY less running the space heater above freezing. Below freezing, however, the space heater runs out of heat and I start losing temperature, thus needing to use the central, while the space heater basically stops cycling and runs constantly.

Then when it gets warm again, the space heater needs to be adjusted manually to prevent over-running up to obscene temps and bills.

Is there a programmable thermostat that will switch on and off a space heater while at warmer outside temps, and then, perhaps based on the duty cycle of the space heater, at some point decide to run the central, while still running the space heater so as to lower the cycling of the central? Or is this asking way too much?
