JADE™ ECONOMIZER MODULE
63-2700—05 14
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).
In AUTO mode dampers controlled by CFM
With 2-speed fan units VENTMAX L (low speed fan) and VENTMAX H (high
speed fan) settings are required. Default for VENTMAX L is 3.2V and
VENTMAX H is 2.8V
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.
In AUTO mode dampers controlled by CFM
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%
