Temperature controller TMS Europe Pro-Ind 220 series Model 221 Mains 230V power Look at the rear connectors and the label on the top of the unit to see what features it offers Not all the label features are connected. My other unit I listed at the same time is also labelled Model 221 and has different connections Thermocouple supplied Panel clamps supplied but might need pliers to tighten up I used these just to indicate temperature
