    My thermostat is showing 3 dashed lines where the temperature display is supposed to be and the thermostat will not control my water furnace 2 stage heat pump.

    Is this a bad thermostat? If so which thermostat would be a direct replacement? Thanks!
    It has worked for 10 years just fine until this morning.

    So, it was the stat and was replaced under warranty with a $530 one.
