FSD NRM
At Terminal Block 3, short Terminals 1 and 2. Verify that the display changes to FSD ALM. Verify the
following:
• Supply fan is OFF
• Outside air and exhaust dampers (if applicable) close
• Return fan is OFF
• Supply fan IGVs close (VAV units)
• Return fan IGVs close (VAV units equipped with return fan)
• Heat Interlock relay is OFF (VAV units)
MTR XXX
If applicable, verify that the display increments following the connected pulse-type meter measuring power.
OAVP 0.00
Verify that the velocity pressure reads 0.00 in. wg with the fan OFF and the mixed-air damper closed
(0 setting).
AQ1 XXX
Verify the displayed value using field-supplied instrumentation located near the sensor.
AQ2 XXX
Verify the displayed value using field-supplied instrumentation located near the sensor.
CUST EN
Verify condensing unit lockout operation by rotating thermostat so display changes to CUST DSB. Reverse
thermostat to change setting back to CUST EN and reenable unit.
DXSD NRM
Verify that the direct expansion cooling shutdown value is normal.
Proceed with the testing of the outputs options (Table 19).
