Does anyone know what Mechie is talking about? He's talking about a resistor for the auto controls. I have the manual HVAC and read the instructions above and monkey says nothing about resistors. My only questions are of monkey's provided site. The site diesn't say what the color of the bulbs are. My other question is of the voltage. And can anyone tell me what the Ma is?
