Latched Heater Control

[GRMAN]

I am new to Labview and this is giving me a little problem. I want to have a setpoint for temperature, and set an on/off range for the heater to turn on and off. For example, if my setpoint is 150 and my on/off range is 5, the heater would come on at 145 and stay on until it reaches 155. I have the heater coming on at 145 but it doesnt go off at 155. Any help is greatly appreciated

Post your code so we can look at it. Also state which version of Labview you are using.

I am including a vi that I used in project a few years ago. What you actually want is one of the sub-vi's called "Process Limits". Just change the values on the controls to match your ranges.

Good luck,
