Two elements, One Kettle, one Temp

[chettoone]

Hi all,

Trying to figure out how to program the BCS-462 to control two electric elements in one kettle, with one input.

The main idea is to turn on both elements to heat up the kettle quickly, and then when temperature gets within 5 degrees of desired temperature, turn one element off, and only use one element to fine tune and control the temperature around the set point.

Any advice on how to achieve this?

Thanks!

There's a few ways to accomplish this, but the first way that comes to mind is to use two states. You'll use two outputs to drive the two elements. One output should have a temp probe association and the second one doesn't need it. In your first state of the process, turn both elements on and then use an exit condition to jump to state 2 when you hit a specified temperature. In state 2, only use the single element that is tied to the temp probe for further heating.
