Description
The Helo OLET 6-1 is a replacement temperature sensor for Helo sauna control systems, supplied complete with a 5 m connection cable. It reads the temperature in the sauna room and feeds it back to the control unit, so the heater holds the bathing temperature you have set. The sensor and cable are the only items included; the control unit and heater are sold separately. Check your Helo control system and part number (SP6214020) before ordering.
