JADE™ ECONOMIZER MODULE
13 63-2700—01
SETPOINTS MAT SET 53ºF 38 to 65 ºF;
increment by 1
Setpoint determines where the economizer will modulate the OA
damper to maintain the mixed air temperature.
LOW T LOCK 32ºF -45 to 80 ºF;
increment by 1
Setpoint determines outdoor temperature when the mechanical
cooling cannot be turned on. Commonly referred to as the
Compressor lockout.
DRYBLB SET 63ºF 48 to 80 ºF;
increment by 1
Setpoint determines where the economizer will assume outdoor air
temperature is good for free cooling; e.g.; at 63 ºF unit will
economizer at 62 ºF and below and not economize at 64 ºF and
above. There is a a 2 ºF deadband.
ENTH CURVE ES3 ES1, ES2, ES3,
ES4, or ES5
Enthalpy boundary “curves” for economizing using single enthalpy.
See “Enthalpy Settings” on page 15 and Product Data sheet form
63-2700 for description of enthalpy curves.
DCV SET 1100ppm 500 to 2000 ppm
increment by 100
Displays ONLY if a CO2 sensor is connected.
Setpoint for Demand Control Ventilation of space. Above the
setpoint, the OA dampers will modulate open to bring in additional
OA to maintain a space ppm level below the setpoint.
MIN POS 2.8 V 2 to 10 Vdc Displays ONLY if a CO2 sensor is NOT connected.
VENTMAX 2.8 V 2 to 10 Vdc
or
100 to 9990 cfm
increment by 10
Displays only if a CO2 sensor is connected.
Used for Vbz (ventilation max cfm) setpoint.
Displays 2 to 10 V if <3 sensors (RA,OA and MA).
VENTMIN 2.25 V 2 to 10 Vdc
or
100 to 9990 cfm
increment by 10
Displays only if CO2 sensor is connected.
Used for Va (ventilation min cfm) setpoint.
Displays 2 to 10 V if <3 sensors (RA,OA and MA). Va is only set if
DCV is used. This is the ventilation for less than maximum
occupancy of the space.
ERV OAT SP 32ºF 0 to 50 ºF;
increment by 1
Only when AUX = ERV
EXH1 SET 50% 0 to 100%;
increment by 1
Setpoint for OA damper position when exhaust fan 1 is powered by
the economizer.
EXH2 SET 75% 0 to 100%;
increment by 1
Setpoint for OA damper position when exhaust fan 2 is powered by
the economizer. Only used when AUX is set to EHX2.
SYSTEM
SETUP
INSTALL 01/01/10 Display order = MM/DD/YY
Setting order = DD, MM, then YY.
UNITS DEG ºF ºF or ºC Sets economizer controller in degrees Fahrenheit or Celsius.
EQUIPMENT CONV CONV
HP(O)
HP(B)
CONV = conventional; enables configuration of shutdown
parameter.
HP(O) = energize heat pump on Cool
HP(B) = energize heat pump on Heat
FAN CFM 5000cfm 100 to 15000 cfm;
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 configured (output is not used)
• ERV= Energy Recovery Ventilator
d
• 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
briefly flash YES and change to NO but all parameters will change
to factory default values.
