MIL-HDBK-1003/3
(1) With the fan ready to start, apply the
optimized start mode command, and observe that the designated
supply fan starts. Observe that the outside air damper and
relief air damper are closed, the return air damper is open, and
the heating coil valve and preheat coil valve (cooling coil
valve) are in the warm-up (cool down) position. Change the
command to occupied mode and observe that the outside air damper,
return air damper, relief air damper, heating coil valve, preheat
coil valve, and chilled water valve are in control, by changing
the controller output.
(2) Apply the minimum outside air mode signal.
Observe that the outside air damper opens to its minimum
position.
(3) With the supply fan running, simulate a high
static pressure input signal at the device by pressure input to
the sensing device. Observe HVAC system shutdown and that the
high pressure alarm is activated. Restart the HVAC system by
manual reset, and observe that the high static pressure alarm is
deactivated.
(4) Index the supply fan static pressure
controller manual-automatic switch to the manual position and
perform a two-point accuracy check of sensing element-to-
controller readout. Place the controller in the local setpoint
mode. Index the controller manual-automatic switch to the
automatic position, and perform the controller tuning procedure.
Set the controller at the specified static pressure setpoint, and
log the mode constant setpoints.
(5) Index the supply air temperature controller
manual-automatic switch to the manual position, and perform the
two-point calibration accuracy check of sensing element-to-
controller readout. Index the controller manual-automatic switch
to the automatic position, and perform the controller tuning
procedure. Set the controller at the temperature setpoint as
shown. Index the mixed air low limit temperature controller
manual-automatic switch to the manual position. Change the
controller output to open the preheat coil valve slightly.
Perform the two-point calibration accuracy check of sensing
element-to-controller readout for outside air, return air, and
mixed air temperatures. Index the mixed air low limit
temperature controller manual-automatic switch to the automatic
position. Apply the economizer mode input signal, and observe
that the outside air, return air, and relief air dampers are
under control. Perform the controller tuning procedure. Set the
controller at the predetermined temperature setpoint.
