Checkout Tests
Use the Checkout menu (see Table 11) to test the damper
operation and any configured outputs. Only items that are
configured are shown in the Checkout menu.
NOTE: See User Interface for information about menu navigation
and use of the keypad.

Energizes the AUX1O output. If Aux setting is:
• NONE= not action taken
• ERV = 24 Vac out. Turns on or signals an ERV that the conditions are not
good for economizing but are for ERV operation††
• SYS = 24 Vac out. Issues a system alarm

When AUX1-0 is set to SYS and there is any alarm (e.g., failed sensors,
etc.), the AUX1-0 terminal has 24 Vac out.
ACTUATOR VOLTAGE LOW
Voltage received at actuator is below expected range
ACTUATOR VOLTAGE HIGH
Voltage received at actuator is above expected range
ACTUATOR STALLED
Actuator stopped before reaching commanded position.

Table 11 illustrates the complete hierarchy. The menu parameters
may be different depending on the configuration. For example, if
there is no DCV (CO
) sensor, then none of the DCV parameters
2
appear.
† When values are displayed, pressing and holding the ▲ or ▼ button
causes the display to automatically increment.
** N/A = Not Applicable.
†† ERV Operation: When in cooling mode AND the conditions are NOT
OK for economizing - the ERV terminal will be energized. In the
Heating mode, the ERV terminal will be energized when the OA is
below the ERV OAT setpoint in the setpoint menu.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage.
Be sure to allow enough time for compressor start-up and
shutdown between checkout tests so that you do not short-
cycle the compressors.
