Description
The Pro-B3 is IKI’s digital control unit for electric sauna heaters up to 10.5 kW, extended to larger heaters with S2-18 or S2-30 power boosters sold separately. Two illuminated dials and clear digital displays set the temperature between 30 and 110 °C and preset heating up to 24 hours ahead, while remote start terminals, door monitoring and an RS485 connection suit hotels and commercial saunas as well as the home. It runs on a 400 V three-phase supply, is wall-mounted outside the sauna room, and arrives with the heater sensor (F1) and installation material; a bench sensor (F2) and humidity sensor (FTS2) are optional extras. Combi mode and a post-drying programme support combi heaters with a vaporiser up to 3.5 kW, though IKI heaters are dry sauna heaters, so with them we recommend dry mode for the soft, generous löyly IKI is known for.
