Balancing the Water Loop for Direct Return Piping 
Several factors must be accounted for when balancing the water loop of a Protocol™ 
installation using direct return piping.  Two major factors stand out: 
 
1 – Balancing to attain the correct water flow for each Protocol™; and 
2 – Balancing the system for Piping Head Loss. 
 
Since these factors have nearly unlimited combinations, finding the appropriate setting for 
each combination is unrealistic.  However, if these factors are separated, their effect on the 
system can easily be defined.
