Main computer is not setup for alarms. U.N.T. c0ntr0lier is not programmed properly: pres..... will always read O. <br />2. Unable 10 test because of ouIside air temperature. <br />3. SUpply Ian status does not work. S1a1us continually shows on. <br />4. intlne Ian S, (IF-5) has 00 points on controller. Fan Is only controlled by local sw~ch in mech. room. <br />5. Fan status is not wired to proper point on c0ntr0lier. <br />6. C0ntr0lIer Is not programmed for warm up mode. <br />7. Economizer mode is locked out on outside airtemperalure set point. <br />8. DX coorong is never locked out. Outslde air temperature is not being written 10 controler and set point for Iocl<out is at 20". <br />9. Low imft protection device is wired to the supply fan status point. No alarm is generated. <br />10. Opening contacts didn, shut down unit. No alarm Is generated. <br />II. Main computer is not setup for alam1s. U.N.T. controller Is not prograrrvned property: pressurewil always read O.Fiterstatus Is <br />not on computer. <br />12. No motorized relief damper installed. <br />13. Radiation valve Is controlled by separate zone set point not from slider on thermostat <br /> <br />. <br /> <br />File: AHU3_FinaIReport.doc <br /> <br />Page 2 of 6 <br />
