STG3 DLY 2.0h
0 min, 5 min,
15 min, then
15 min intervals.
Up to 4 hrs or OFF
COOLING STAGE 3 DELAY
Delay after stage 2 cool has been active. Turns on second stage of
cooling when economizer is first stage and mechanical cooling is
second 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.

Used for alarm for when the DA air temperature is too high. Set
upper range of alarm, above this temperature the alarm will show
on the display.
DCVCAL ENA MAN

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.

increments
TIME DELAY ON SECOND STAGE ECONOMIZING
When in economizing mode this is the delay for the high speed fan
to try to satisfy the call for second stage cooling before the first
stage mechanical cooling is enabled.
CHECKOUT
DAMPER MINIMUM
POSITION
N/A N/A
The checkout for the damper minimum position is based on the
system.
DAMPER OPEN N/A N/A
Position damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make
sure you pause in the mode to allow exhaust contacts to energize
due to the delay in the system.
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 AUX1-O N/A N/A
Energizes the AUX 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
CONNECT EXH1 N/A N/A Closes the power exhaust fan 2 relay (EXH1)
ALARMS
Alarms display only when they are active. The menu title “ALARMS(#)” includes the number of active alarms in parenthesis ( ).
When using SYLK bus sensors, “SYLK” will appear on the screen, and when using 20k OA temperature sensors, “SENS T” will
appear on the screen
MA T SENS ERR N/A N/A

Mixed air sensor has failed or become disconnected - check wiring
then replace sensor if the alarm continues.

check wiring then replace sensor if the alarm continues.
OA SYLK H ERR N/A N/A
RA SYLK T ERR N/A N/A RETURN AIR S-BUS SENSOR ERROR
