KTNH models are much stronger than KTSH(or other local sauna stove) in body, also it has (three-phase) limit-temperature protection function. For example, if your setting temp. Is 50C, when the room temperature arrive at 50C, the heater heating should be timeout, but at this time, if this thermostat function is broken/malfunction, then the temperature will continue increasing(it won't timeout as it should be). Don't worry, The KTNH heater's limit-temperature protection function will work, which is only permitted the temperature arrived at 55C, then this function will force the sauna heater stopped heating. So it won't produce safe problem for heater itself and people, 100% safe guarantee.
