50 for the ECO series

and reduced emissions

An additional advantage: The pump does not require separate motor protection because it is short-circuit proof

TECH EU-21 CWU Pumpensteuerung Umwälzpumpe Kessel Boiler Sensor the EU-21 reduces unnecessary operatingThe TECH EU 21 CWU is a compact controller for automatic regulation of a circulation pump between the boiler and the hot water tank or buffer tank. It operates based on temperature difference and reliably protects the system from unnecessary pump operation and frost. Highlights Benefits Differential temperature control Pump runs only when there is actual heat demand Two temperature sensors Separate detection of boiler and tank buffer temperature Frost
