System Setup
INSTALL
01/01/10 Display order = MM/DD/YY Setting order = DD , MM, then YY.
UNITS DEG ° F ° For° C
Sets economi zer controller in degrees Fahrenheit or Celsius.
EQUIPMENT
CONV Conventional or HP
CONV = conventional; HP O/B = Enable Heat Pump mode. Use
AUX2 I for Heat Pump input from thermostat or controller.
AUX21
W SD/W or HP(O)/HP(B)
In CONV mode: SD + Enables configuration of shutdown
(default); W = Informs controll er 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 TYPE
2 speed 1 speed/2 speed
Sets the economizer controller for operation of 1 speed or 2 speed
suppl y fan. (Note: for 3 speed units (48/50LC 07- 12), setpoint is a
2 speed).
FAN CFM
5000 cfm
100 to 15000 cfm
Increment by 100
This is the capacity of the RTU. The value is found in the Project
Submittal documents for the specific RTU .
AUX OUT
NONE
NONE
ERV
EXH2
SYS
NONE = not configured (output is not used).
ERV = Energy Recovery Ventilation.
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 V ac is input “INPUT” to the OCC terminal. If no occupancy
output from the thermostat then change p rogram to “ALWAYS” OR
add a j umper from terminal R to OCC terminal.
FACTORY
DEFA ULT
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.
Adva nced Setup
MA LO SET 45%
35 to 55° F
Increment by 1%
Temperature to achieve F reeze Protection (close damper and
alarm if temperature falls below setup value).
FREEZE
POS
CLO CLO or MIN Damper position when freeze protection is active (closed or MIN POS).
CO2 ZERO 0ppm
0 to 500 ppm
Increment by 10
CO2 ppm level to match CO2 sensor start level.
CO2 SPAN 2000ppm
1000 to 3000 ppm
Increment by 10
CO2 ppm span to match CO2 sensor.
STG3 DLY 2.0h
0 min, 5 min, 15 min,
then 15 min intervals.
Up to 4 h or OFF
Delay after stage 2 cool has been active. Turns on 2nd stage of
cooling when economizer is 1st stage and mechanical cooling is
2nd stage. All ows three stages of cooling, 1 economizer and 2
mechanical. OFF = no Stage 3 cooling.
SDDMPR
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
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.
MATTCAL 0.0° F +/- 2.5° F
Allows for the operator to adjust for an out of calibration
temperature sensor.
OA T CAL 0.0° F +/- 2.5° F
Allows for the operator to adjust for an out of calibration
temperature sensor.
OA H CAL 0% RH +/- 10% RH
Allows for operator to adjust for an out of calibration humidity
sensor.
RA T CAL 0.0° F +/- 2.5° F
Allows for operator to adjust for an out of calibration temperature
sensor.
RA H CAL 0% RH +/- 10% RH
Allows for operator to adjust for an out of calibration humidity
sensor.
DA T CAL 0.0° F +/- 2.5° F
Allows for the operator to adjust for an out of calibration
temperature sensor.
