What to do if my Venstar T1010 Thermostat dims or disappears when using 4 wires?

If your Venstar Thermostat display dims or disappears when using 4 wires (R, G, W, Y) and the air conditioning equipment tries repeatedly to turn on but cannot, it's likely due to insufficient power for "power sharing." To resolve this, connect a 270 ohm, 10-watt power resistor at the furnace as illustrated in the manual.
