FACTORY DEFAULT
NO
NO or YES
Resets all set points to factory defaults when set to YES. LCD will briefly
flash YES and change to NO but all parameters will change to the
factory default values.

STG3 DLY
2.0h
0 min, 5 min, 15 min, then
15 min intervals. Up to 4 h
or OFF
Delay after stage 2 for cool has been active. Turns on 2
nd
stage of
cooling when economizer is 1
st
stage and mechanical cooling is 2
nd
stage. Allows three stages of cooling, 1 economizer and 2 mechanical.
OFF = no Stage 3 cooling.
SD DMPR POS
CLO
CLO or OPN
Indicates shutdown signal from space thermostat or unitary controller.
When controller receives 24 Vac input on the SD terminal in conventional
mode, the OA damper will open if programmed for OPN and OA damper
will close if programmed for CLO. All other controls, e.g., fans, etc. will
shut off.
DCVCAL ENA

AUTO
Turns on the DCV automatic control of the dampers. Resets ventilation
based on the RA, OA and MA sensor conditions. Requires all 3 RA, OA
and MA sensors.

Positions damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make sure
you pause in this mode to allow exhaust contacts to energize due to the
delay in the system.

Closes the Y2---O relay (Y2---O)
CONNECT AUX
n/a
n/a
Energizes the AUX output. If Aux setting is:
S
NONE --- not action taken
S
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
S
SYS --- 24 Vac out. Issues a system alarm

When AUX is set to SYS and there is any alarm (e.g., failed sensors,
etc.), the AUX terminal has 24 Vac out.
NOTE
: The alarms listed are examples. Additional alarms display depending on the parameter settings and configuration.
For example if you do not have a DCV (CO
2
) sensor, then none of the DCV parameters appear.

Table 2 illustrates the complete hierarchy. your menu parameters may be different depending on your configuration.
For example if you do not have a DCV (CO
2
) sensor, then none of the DCV parameters appear.

When values are displayed, pressing and holding the
Y
or
B
button causes the display to automatically increment.
c
n/a = not applicable
d
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.
