Does anyone know of a PID controller that can have three setpoints, selectable by volt free normally open contacts?
 
Honeywell UDC 3200 1/4 DIN single loop controller has 3 setpoints, any of which can be selected from a front panel pushbutton labeled "SP Select" or with the the optional digital inputs (dry contact).

Ascon AC-20 programmable multiloop controllers or similar controllers can be programmed for 2 or more setpoints. The required setpoint can be made selectable using the DI's for certain preset conditions that can be programmed with ease.
