Thank you for viewing. This is a stainless steel sauna heater with digital temperature control. The cord is not connected, and wiring is required, but there are no instructions for wiring, etc. Since the operation has not been confirmed, it is sold as-is (junk) without warranty. At the time of purchase, it was described as being for 200V, but the label on the main unit indicates 380V 4.5kw. The wiring inside the controller is as shown in the photo (with the controller cover removed). - Shape: Oval - Material: Stainless steel - Controller: Digital controller - Size: Medium
