I replaced an existing automatic thermostat with a new 2441TH Insteon thermostat today. The previous thermostat was wired with a 5 wire cable. I carefully moved the wires to the new Insteon device. The screen on the Insteon never powers up (remains blank) and no LEDs are lit. Maybe this is a defective unit?
I took a picture of the completed wiring (attached)
Thanks in advance
