Application • This electronically controlled mini instantaneous water heater can supply DHW to one hand washbasin. • Can be operated with pressure taps or non-pressurised taps.
Convenience features • Electronically controlled mini instantaneous water heater with closed-loop control, outlet temperature sensor and variable flow rate limitation. • Accurate temperature delivery up to the maximum output. • Internal temperature limit. • Including special aerator for perfect water flow pattern and integral flow controller for fitting in existing taps. • Anti-scalding protection for high inlet temperatures via automatic output matching. • Suitable for oversink or undersink installation.
Efficiency • Electronic output control for energy efficient and water saving operation. In conjunction with closed-loop control, the outlet temperature sensor ensures the set temperature achieved is accurate to the degree. For this, only the amount of energy required is expended; there is no need to add cold water at the tap. • The water is heated directly at the draw-off point and only when required. This prevents the energy and water losses caused by long pipe runs. This ensures maximum energy efficiency. • Suitable for preheated water from solar thermal and heat pump systems.
Installation • PROFI-RAPID installation system for time saving and straightforward installation. Straightforward wall mounting with 2-point attachment. The back panel simultaneously acts as a drill template; slots compensate for drill hole discrepancies. • The appliance cover and internal assembly can be removed with just one hand movement. • Fast water connection thanks to external metal water fittings for direct, universal installation of taps. • Simple electrical connection as power cable is wired up as standard. • Fault analysis with LED diagnostic traffic light.
Safety • Maintenance-free bare wire heating system, suitable for hard and soft water. • Safety system with high pressure switch and electronic temperature monitoring.
