To Next PageTo Next PageWhy is the display blank on my Venstar Thermostat?
A blank display on your Venstar Thermostat typically indicates a lack of proper power. Ensure that the power to the furnace is turned on and that there is 24VAC between R and W. If the C wire is used, there should be 24VAC between R and C.
How to fix Venstar TSTATEZ Thermostat when AC repeatedly tries to turn on?
If your air conditioning equipment repeatedly tries to turn on but fails, and the display dims or disappears when using 4 wires (R, G, W, Y), it indicates there is not enough power available. To resolve this, connect a 270 ohm, 10 watt power resistor at the furnace.
