Notes 
* Best used with supply water reset from outdoor air temperature.
 
** Can dead-head pumps.  Use with VFD-controlled pumps with maximum pressure cut-out
 
*** Maximum operating differential pressure.  Static close-off pressure may be higher. Maximum pressure for quiet service may be less.
 
**** Stem down to close
 
***** Stem up to close
