It works because the tech set it. I cannot change the temp or the mode. Have read the instructions twice and tried many times to reset it with no sustained results.
Came with a new heat pump system, professionally installed. Very difficult to find programming how-to, as the online info does not apply to this model. Schedule does not support 7, 5-2 5-1-1,1 even though the box clearly says the unit offers this flexibility.
We have this thermostat at our second home at which we allow guests to stay. It is perfect for keeping the temperature at a level of efficiency when we are not there but allowing us to move the temperature to a more normal level just prior to the guests' arrival. The equipment responds well remotely. Glad we made the purchase!
