Product detailsAPPLICATION: Comfort instantaneous water heater suitable for DHW supply to multiple draw-off points (single and group supply), e.g. simultaneous supply to the bathroom and kitchen. Sealed unvented, pressure-tested appliance for use with all commercially available pressure taps.
EQUIPMENT/CONVENIENCE: Instantaneous water heater with full electronic control and 4i technology. Accurate temperature delivery at all times thanks to electronic flow rate control. Variable, digital temperature selection via rotary selector, temperature adjustment in 0.5 °C increments. Backlit multifunction display to show values such as set temperature, current power consumption, energy consumption, flow rate, time, status and service information. ECO button. Two temperature memory buttons for programmable preferred temperatures. Four wellness shower programs, automatic bath filling. LED scalding risk indicator at temperatures above 43 °C or unexpectedly high outlet temperatures caused by preheated water; displays the inlet temperature in the lower section. Individually adjustable temperature limit (childproofing). Optional convenient remote control available. Rotatable appliance cover and programming unit for increased operating convenience in undersink installations.
EFFICIENCY: Energy and water savings of up to 30 % through full electronic output control with 4i technology. 3 sensors and an additional motorised valve ensure accurate temperature delivery at all times. For this, only the amount of energy actually required is expended; there is no need to add cold water at the tap. This ensures maximum energy efficiency. ECO mode can be individually selected for particularly economical operation. Transparent energy and water consumption. Suitable for preheated water (e.g. in solar thermal and heat pump systems).
PROFI-RAPID INSTALLATION: PROFI-RAPID – The improved installation system for even quicker and simpler installation. Easy replacement of all conventional instantaneous water heaters. Easy wall mounting: Universal mounting rail with integrated compensation for unevenness in the wall and drill hole discrepancies; designed to match commonly used fixing points. Fast and universal water connection: Enlarged installation area with pivoting cold water inlet, threaded water fittings, twin nipple technology for easy replacement, installation on finished/unfinished walls with 3-way shut-off, suitable for plastic pipes (observe manufacturer's instructions). Straightforward electrical connection: From above or below; cable entry gland for cable.
PROFI-DIRECT: Fault memory can be called up on the display for fault analysis, plus LED diagnostic traffic lights. Inner assembly can be removed using the handle.
SAFETY: Rapid bare wire heating system, suitable for hard and soft water. Electronic safety concept with air bubble detection. Anti-scalding protection adjustable only by qualified contractors, for permanent limiting of the water outlet temperature to max. 43, 50 or 55 °C.
