IR33 TEMPERATURE CONTROLLER

The IR33 controller is the replacement for the IR32 range. It has all

of the functions of the IR32 plus additional features such as PID

control. All of the parameters on the IR33 have the same meaning

as on the IR32 so the IR33 will work in exactly the same way as

the IR32 if the same parameters are entered.
