3. Appliance description

The electronically controlled small instantaneous water heater maintains a constant outlet temperature up to its output limit, irrespective of the inlet temperature.This appliance has been factory-set to the outlet temper-ature required for washing hands. Once this temperature has been reached, the PCB automatically reduces the output. The output is matched to the required tempera-ture, this prevents the temperature being exceeded.The appliance heats the water directly at the draw-off point as soon as the tap is opened. The short pipe runs ensure that energy and water losses are minimal.The DHW output depends on the cold water temperature, the heating output and the ow rate.The bare wire heating system is suitable for hard and soft water areas. This heating system has a low susceptibility to scale build-up. The heating system ensures quick and efcient DHW provision at the hand washbasin.Your qualied contractor can adjust the maximum tem-perature and ow rate (see chapter "Commissioning / Settings").Fitting the special aerator supplied provides an optimum water jet.Operation - for users and contractors

The appliance heating system switches on automatically as soon as you open the DHW valve at the tap or activate the sensor of a sensor tap. The water is heated. The water temperature can be adjusted at the tap: For initial ow rate and ow rate limiting, see chapter "Specication". Increasing the temperature » Reduce the ow rate at the tap. Reducing the temperature » Open the tap further or add more cold water. Following an interruption of the water supply See chapter "Commissioning / Recommissioning".
