CHECKOUT
DAMPER VMIN .HS n/a n/a Positions OA damper to VMIN High Speed position
DAMPER VMAX .HS n/a n/a Positions OA damper to VMAX High Speed position
DAMPER OPEN n/a n/a Positions OA damper to the full open position.
DAMPER CLOSE n/a n/a Positions damper to the fully closed position
CONNECT Y1---O n/a n/a Closes the Y1---O relay (Y1---O)
CONNECT Y2---O n/a n/a Closes the Y2---O relay (Y2---O)
CONNECT AUX1O n/a n/a 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 good for ERV
operation.
d
• SYS ‒ 24 Vac out. Issues a system alarm
ALARMS(_)
Alarms display only when they are active. The menu title “ALARMS(_)”
includes the number of active alarms in parenthesis ( ).

When AUX1-0 is set to SYS and there is any alarm (e.g., failed
sensors, etc.), the AUX1-0 terminal provides 24 Vac out.

CHECKOUT TESTS
Use the Checkout menu (see Table 11) to test the damper operation
and any congured outputs. Only items that are congured are
shown in the Checkout menu.
NOTE: See User Interface for information about menu navigation
and use of the keypad.
To perform a Checkout test:
1. Scroll to the desired test in the Checkout menu using the ▲
and ▼ buttons.
2. Press the button to select the item.
3. RUN? appears.
4. Press the button to start the test.
5. The unit pauses and then displays IN PROGRESS.
6. When the test is complete, DONE appears.
7. When all desired parameters have been tested, press the
↑ (Menu up) button to end the test.
Checkout test can be performed at any time during the operation of
the system as a test that the system is operable.
CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in damage to equipment
Be sure to allow enough time for compressor startup and
shutdown between checkout tests so that you do not short-cycle
the compressors.
