Narvi Logi sauna controller manages the Narvi Heat industrial electric heater in pools, hotels and other professional saunas. Control runs over the facility local network, so staff can operate it from a control room or reception.
The package includes two waterproof PT100 temperature sensors with overheat protection. Temperature adjusts from 60 to 105 °C with 1 °C accuracy, with two operating periods per day, user and admin access, anomaly alerts, maintenance program and resistor group rotation. Modbus TCP allows building automation integration, with optional steam and lighting control.
