Notes:
1 . The supply fan % output is in reference to the user selected maximum unit fan speed.
2 . The supply fan and compressor outputs shall follow all startup and shutdown requirements prior to moving through test
mode steps that change the states of the compressor output from ON to OFF or OFF to ON.
3 . All compressor % outputs are in reference to the 100% capacity point per unit tonnage.
(a) During step 1 of the short-circuit based service test sequence; the IGV output is driven to 0%. However, for the 2.2kOhm resistance based service test
step approach - the IGV output is driven to 100%.
(b) For multi-zone VAV units, the VFD command when "In-Control" will be controlled based on supply air pressure requirements for the unit.
(c) Condenser fan operation will be controlled based on the active OAT as during normal operation.
(d) VAV boxes are commanded to an open position during service test. However, six minutes must be allowed for the VAV boxes to reach a fully opened
position. During these 1st six minutes, duct static pressure control has control priority over the supply fan command of 100%.

Notes:
1 . The supply fan % output is in reference to the user selected maximum unit fan speed. Unit will operate at 100% fan
speed during heating unless configured for SZVAV heating operation.
2 . The supply fan and compressor outputs shall follow all startup and shutdown requirements prior to moving through test
mode steps that change the states of the compressor output from ON to OFF or OFF to ON.
3 . All compressor % outputs are in reference to the 100% capacity point per unit tonnage.
(a) First % shown is the control signal percentage. Second % is the actual fan speed percentage.
(b) Condenser fan operation will be controlled based on the active OAT as during normal operation.
