Heat Pump, Auxiliary Heat, and Adaptive Intelligent Recovery
We have a heat pump and a White-Rogers programmable thermostat, model number 1f82-261. We have checked and it is properly set to use the Energy Management Recovery (EMR) option. However, it never goes on before the program is set to have the temperature change. You can see/hear it click on and off when the program calls for a temperature change. And, now that it is the winter, it is using the auxiliary heating a lot to get up to the set temperature at the programmed time instead of starting early and getting there gradually without the auxiliary heat. How do we know if the White-Rogers programmable thermostat is working properly? Specially, how do we know the EMR option is working? How do we stop the auxiliary heat from being used?
If we can't get the EMR to work, would it be better to keep the heat pump at a constant temperature? I know most people say that a programmable thermostat, which allows you to change the temperature when you are not home is better, and that it does not use more power to reheat the house when you get home. But, is that true for a heat pump using the auxiliary heat?
