2SP FAN DELAY
5 Minutes
0 to 20 minutes in 1
minute increments
TIME DELAY ON SECOND STAGE ECONOMIZING
When in economizing mode this is the delay for the high speed fan to try to sat-
isfy the call for second stage cooling
b
efore the first stage mechanical cooling
is ena
b
led.
CHECKOUT
DAMPER MINIMUM
POSITION
N/A
N/A
The checkout for the damper minimum position is
b
ased on the system.
DAMPER OPEN
N/A
N/A
Position damper to the full open position.
Exhaust fan contacts ena
b
le 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
b
ut 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 num
b
er of active alarms in parenthesis ( ). When using SYLK
b
us
sensors, “SYLK” will appear on the screen, and when using 20k OA temperature sensors, “SENS T” will appear on the screen

under voltage and actuator count. Replace actuator if damper is mova
b
le and
supply voltage is
b
etween 21.6 V and 26.4 V. Check actuator count on STA-
TUS menu.
FREEZE ALARM
N/A
N/A
Check if outdoor temperature is
b
elow the LOW Temp Lockout on setpoint
menu. Check if Mixed air temperature on STATUS menu is
b
elow the Lo Set-
point on Advanced menu. When conditions are
b
ack in normal range then the
alarm will go away.
