JADE™ ECONOMIZER MODULE
21 63-2700—05
SETPOINTS MAT SET 53ºF 38 to 70 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 17 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.
With 2-speed fan units MIN POS L (low speed fan)
and MIN POS H (high speed fan) settings are
required. Default for MIN POS L is 3.2V and MIN
POS H is 2.8V
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).
With 2-speed fan units VENTMAX L (low speed fan)
and VENTMAX H (high speed fan) settings are
required. Default for VMAX L is 3.2V and VENTMAX
H is 2.8 V
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.
With 2-speed fan units VENTMIN L (low speed fan)
and VENTMIN H (high speed fan) settings are
required. Default for VENTMIN L is 2.5V and
VENTMIN H is 2.25V
ERV OAT SP 32ºF 0 to 50 ºF;
increment by 1
Only when AUX1 O = ERV
EXH1 SET 50% 0 to 100%;
increment by 1
Setpoint for OA damper position when exhaust fan
1 is powered by the economizer.
With 2-speed fan units Exh1 L (low speed fan) and
Exh1 H (high speed fan) settings are required.
Default for Exh1 L is 65% and Exh1 H is 50%
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
AUX1 O is set to EHX2.
With 2-speed fan units Exh2 L (low speed fan) and
Exh2 H (high speed fan) settings are required.
Default for Exh2 L is 80% and Exh2 H is 75%
a
ERV Operation: When in Cooling mode AND the conditions are NOT OK for economizing - the ERV terminal will be energized. In
the Heating mode the ERV terminal will be energized when the OA is below the ERV OAT setpoint in the setpoint menu.
