It can't run a heater on its own. It sits alongside your Xenio or Fenix control unit and shares the heater load, so a single touch panel can drive a far more powerful heater than the standard power unit could handle by itself.\u003c\/p\u003e\n\u003cp\u003eIt's the piece that makes large home saunas, commercial saunas and high-output heaters work with the same modern controls you'd use on a smaller build.\u003c\/p\u003e\n\u003ch4\u003eDo you need one?\u003c\/h4\u003e\n\u003cp\u003eYou'll need an LTY17 if either of these applies:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour heater is rated higher than your control unit can switch.\u003c\/strong\u003e A Xenio CX170 or Fenix FX170 handles up to 17 kW on its own, so any heater above 17 kW needs an LTY17.

For the Qube Pro 360, a control unit plus one LTY17 tops out at 34 kW with each power group limited to 17 kW, which suits its 30 kW setting. The full 36 kW setting needs a different control setup, so talk to us first and we'll confirm the right combination.\u003c\/p\u003e\n\u003cp\u003eIf your heater sits comfortably under your control unit's rating and has a single supply cable, the power unit supplied with the control unit is all you need.
