FAN SPEED (c)
1 speed 1 speed/ 2 speed
See unit
nameplate:
Digit 15 = 0 or 1 -
1 speed;
Digit 15 = 7 or 9 -
2 speed
Sets economizer controller for
operation of 1 speed or 2 speed supply
fan. The controller does not control the
fan but positions the OA and RA
dampers to the heating or cooling
mode. See page 23 for modes and
position.
Note: 2-speed fan option also needs
Heat (W1) programmed in AUX
2 In.
FAN CFM (c)
5000cfm
100 to 15000 cfm;
increment by 100
5000 cfm
This is the capacity of the RTU. The
value is found in the Unit Catalog. The
cfm of the fan is only used with DCV
CAL ENABLE AUO.

AUX1 OUT is a programmable output
used for System Alarm output.
OCC (c)
INPUT INPUT or ALWAYS 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 add a jumper from
terminal R to OCC terminal.
FACTORY DEFAULT (c) NO NO or YES NO
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 factory
default values.
MA LO SET (c) 45ºF

2.0h
Delay after stage 2 for cool has been
active. Turns on 2nd stage of
mechanical cooling when economizer
is 1st stage call and mechanical
cooling is 2nd stage call. Allows three
stages of cooling, 1 economizer and 2
mechanical. OFF = no Stage 3 cooling.
SD DMPR POS CLO
CLO
OPN
CLO
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., Y1-O, EXH1, etc. will
shut off.
