If a heating or cooling system is operated with too much water, this cannot be converted into higher heating or cooling capacity. In this case, the temperature spread between supply and return decreases. The so- called low delta T syndrome occurs. This impairs the efficiency of the entire system and increases the energy requirement of the pumps and generating system. Possible causes of low delta T syndrome are operational soiling of the heat exchanger, incorrectly dimensioned control valves, lack of hydronic balancing and differen- tial pressure fluctuations.36%e r u t a r e p m e t/r e w o PAdjustable delta T limiting valuea e r a t n e c ffi e niI
