Ok guys, i need some help. I am looking for a timing mechanism for this controller. Trying to save a local school some money instead of having to put in a EHC. Any where in your areas that might have one or repair one? Must be missing some cogs on the gears cause it is skipping zones. Fine tuning the run time knobs had no affect. Trying not to have to send it to TORO in CA. Been there done that.
