Hygrotherm VU

Sauna control for dry saunas (80…110…°C) or wet saunas (40…60…°C), max. 9kW

Electronic sauna control for “Finnish” (dry) or “hygro” (wet) saunas. Temperature and humidity can be adjusted smoothly in accordance with the desired type of sauna – “Finnish” or “hygro”. The device has a switch for light / fan / heating, a pre-selection timer (max. 12 hours), illuminated displays ON/OFF / dry/hygro mode / furnace heating phases / evaporator heating phase, low-water detection and acoustic low-water signal, sensor failure/sensor short circuit, heating-time limitation (6h/12h/without), connection for remote ON/OFF switching. The automatic follow-up dry heating (+60…+80…°C, max. 3.5h) with fan connection prevents mould formation. A temperature sensor with safety thermal cut-out (141…°C) and 3m silicon cable is included in the delivery. It is possible to increase the load using LG x/xx power switching units. The light, fan and internal electronics are all fused separately.
