On/Off Rate

On/Off Rate is for optional additives. You define the Product Rate and Rate Units ahead of time, so the operator doesn't need to do any calculations in the field — during Mix Preview, they just enter 1 (ON) to include the product in the mix, or 0 (OFF) to skip it entirely.

Use this for products that aren't always needed — a drift retardant, a conditioner, an occasional additive — where the rate is fixed whenever it's used, but whether it's used at all should be an in-field decision.

See Mix Preview for how this behaves live during a mix.
