SYSTEM
SETUP
AUX2 I SD SD/W or HP(O)/HP(B) In CONV mode:
SD = Enables conguration of shutdown (default);
W = Informs controller that system is in heating mode.
In HP O/B mode:
HP(O) = energize heat pump on Cool (default);
HP(B) = energize heat pump on Heat.
FAN SPEED 1 speed 1 speed/2 speed Sets economizer controller for operation of 1 speed or 2 speed supply

increment by 100
This is the capacity of the RTU. The value is found on the label from the
RTU manufacturer.
AUX OUT NONE NONE
ERV
EXH2
SYS
• NONE = not congured (output is not used)
• ERV= Energy Recovery Ventilatord
• EXH2 = second damper position relay closure for second exhaust fan.
• SYS = use output as an alarm signal
OCC INPUT INPUT or ALWAYS
When using a setback thermostat with occupancy out (24 Vac), the 24
Vac is input “INPUT” to the OCC terminal. If no occupancy output from
the thermostat then change program to “ALWAYS” OR ad a jumper
from terminal R to OCC terminal.
FACTORY DEFAULT NO NO or YES Resets all set points to factory defaults when set to YES. LCD will
briey ash YES and change to NO but all parameters will change to
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 2nd stage of
cooling when economizer is 1st stage and mechanical cooling is 2nd
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.
DA LO ALARM

DCVCAL ENA MAN MAN (manual)
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. Not aperable with 2-speed fan.

2-SPEED FAN DELAY 5 MIN 0-20 Min
in 1 min increments
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
rst stage mechanical cooling is enabled.
CHECKOUT DAMPER VMIN-HS
Positions damper to VMIN position.
DAMPER VMAX-HS
(LS)
Positions damper to VMAX position. With 2-speed fan units the
damper will position to VMAX low speed fan.
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)
