Supply water temperature is bouncing <br />between 150' and 180.. Boilers need tuning to improve temperature control. Pump leadl1ag does not work. If <br />one pump fails the second pump does not turn on as a backup. No set points are available on the computer. <br />The heating water differential pressure is reading .163 P.S.I. and the control valve is open 100%. <br /> <br />. <br /> <br />File: Boiler_FinaIReport.doc <br /> <br />Page 2 of 3 <br />
