You'll have to see what ""Cell Types"" your control box can handle (instructions below). You would only want to get a cell that your control box has an option for. Many times, older T-5 models will only have the choice between T-5 and T-15. If that is the case, the T-15 is recommended; bigger is better, it just means your system will work less hard to do the same job and will last you longer.
