JADE™ ECONOMIZER MODULE
21
63-2700—11
SETPOINTS MAT SET
53ºF
38 to 70 ºF;
increment by
1
The economizer will modulate the OA damper to maintain the mixed
air temperature at the setpoint.
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. At or below the setpoint the Y1-O and
Y2-O will not be energized on the controller.
DRYBLB SET
63ºF
48 to 80 ºF;
increment by
1
Dry bulb setpoint will only appear if using dry bulb change over.
Setpoint determines where the economizer will assume outdoor air
temperature is good for free cooling; e.g.; at 63 ºF setpoint unit will
economizer at 62 ºF and below and not economize at
64 ºF and above. There is a a 2 ºF deadband.
DRYBLB DIF
Available firmware
1.15, June 2018, and
later.
0ºF
0 to 6ºF;
increment by
2
Drybulb Differential will only show if using dual drybulb, i.e., when an
outdoor air temperature sensor C7250 is attached to OAT terminals,
and a C7400S sensor is wired to S-Bus and configured for RAT (return
air). Free cooling will be assumed whenever OA Temp is below
RAT
minus this drybulb differential setting
.
ENTH CURVE
ES3
ES1, ES2,
ES3,
ES4, or ES5
ES curve will only appear if using enthalpy changeover.
Enthalpy boundary “curves” for economizing using single enthalpy.
See page 22 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
Displays only if a CO2 sensor is connected.
Used for Vbz (ventilation max cfm) setpoint. VENTMAX is the same
setting as MIN POS would be if you did not have the CO2 sensor.
100 to 9990
cfm
increment by
10
If OA, MA RA and CO2 sensors are connected and DCV CAL ENABLE is
set to AUTO mode, the OA dampers are controlled by CFM and displays
from 100 to 9990 cfm.
2 to 10 Vdc
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
Displays only if CO2 sensor is connected.
Used for Va (ventilation min cfm) setpoint. This is the ventilation
requirement for less than maximum occupancy of the space.
100 to 9990
cfm
increment by
10
If OA, MA RA and CO2 sensors are connected and DCV CAL ENABLE is
set to AUTO mode, the OA dampers are controlled by CFM and displays
from 100 to 9990 cfm.
2 to 10 Vdc
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
