Device Calibration Checks. The actuators or devices listed below checked for calibration. This is a spot <br />check on a sample of the calibrations done during field verification checklist and startup. <br />"In calibration" means observing readout in the BAS and going to theaetuator or controlled.device and veriJYing thai the BAS <br />reading is correct. For items out of calibration or adjustment, fix now ifeasy, via an offset in the BAS. or a mecbanicallix. <br /> <br />Device or Actuator & Location 1st Site Final BAS Pass <br /> Procedure I State BAS Value Observation Reading YIN <br />D.X. cooling stages control <br />Stage I I.

Verity thai readings in BAS reasonably <br />.correspond to the actual positions. For D.X. coolin2 control: Procedure 2. Lower dischatge air sel point to 20F below discharge air <br />temperaltrre. Verity BAS reading says DX cooling is staged on. Visually verity cooling relays are being called on. For bealin. coil <br />valves (NO): Procedure 2. Raise dischatge set point to 20F above<lischarge temperature. Verity BAS reading says heating coil control <br />valve is 100% open. Visually verity valve is 100% open. ForD.X. coolin. coil control Procedure 3. Set discharge air sel poinl to 20F <br />above dischatge air temperature. Verity BAS reading says D.X. cooling is staged off. Visually verity cooling relays are being called off. <br />For heatin. coil valves (NCl: Procedure 3. Sel discharge air gel point 10 20F below discharge air temperature. Verity BAS reading says <br />heating control valve is closed_ Visually verify valve is closed. <br />". Command damper closed and verity thai damper is shul and BAS reads shut. 2. Do the same; conunanding damper fully open. <br />"'VFD: Procedure 1. Verity that the minimum and maxim\lU\ speeds of the variable frequency drives match the building automation <br />system reading. <br /> <br />Notes:" Testing 01 AHU 112 was performed using HVACPm. <br />1.
