STEP #4 TEST OPERATION Turn the power on to the Heating/Air AUTO Conditioning system. Press the MODE button repeatedly until AUTO the HEAT icon appears on the display. Press the UP or DOWN buttons until the set temperature is 10 degrees above room temperature.
TROUBLESHOOTING SYMPTOM: When using 4 wires (R, G, W, Y), AUTO the air conditioning equipment tries repeatedly to turn on, but cannot. At times the display dims or disappears. CAUSE: There is not enough power available to "power share". REMEDY: Connect a 270 ohm, 10 watt power resistor at the furnace as shown below.
