This means the thermostat did not detect a heater connected to Mysa's load wire. A good way to check this is to make sure the wires connecting Mysa to your heater are touching in the wire nut. As more wires are put in a wire nut it is possible for them to come loose from each other. 

E4, H1, Hi and F6
