JADE™ ECONOMIZER MODULE
17 63-2700—05
SETUP AND CONFIGURATION
Before being placed into service, the JADE™ Economizer
module must be setup and configured for the installed system.
IMPORTANT
During setup, the Economizer module is live at all
times.
The setup process uses a hierarchical menu structure that is
easy to use. You press the
and arrow buttons to move
forward and backward through the menus and press the
↵
button to select and confirm setup item changes.
Time-out and Screensaver
When no buttons have been pressed for 10 minutes, the LCD
displays a screen saver, which cycles through the Status items.
Each Status items displays in turn and cycles to the next item
after 5 seconds.
Enthalpy Settings
When the OA temperature, enthalpy and dew point are below
the respective setpoints, the Outdoor Air can be used for
economizing. Fig. 16 shows the new single enthalpy
boundaries in the W7220. There are 5 boundaries (setpoints
ES1 through ES5), which are defined by dry bulb temperature,
enthalpy and dew point.
Refer to Table 6 for the ENTH CURVE setpoint values.
ALARMS(_) MA T SENS ERR n/a n/a Alarms display only when they are active. The menu title “ALARMS (_)”
includes the number of active alarms in parenthesis ().
CO2 SENS ERR n/a n/a
OA T SENS ERR n/a n/a
DA ENTHL ERR n/a n/a
SYS ALARM n/a n/a When AUX1 O is set to SYS and there is any alarm (e.g., failed sensors,
etc.), the AUX1 O terminal has 24 Vac out.
ACT UNDER V n/a n/a Voltage received by Actuator is above expected range
ACT OVER V n/a n/a Voltage received by Actuator is below expected range
ACT STALLED n/a n/a Actuator stopped before achieving commanded position
NOTE: The alarms listed are examples. Additional alarms display depending on the parameter settings
and configuration.
a
Table 5 illustrates the complete hierarchy. Your menu parameters may be different depending on your configuration.
For example if you do not have a DCV (CO
2
) sensor, then none of the DCV parameters appear.
b
When values are displayed, pressing and holding the or button causes the display to automatically increment.
c
n/a = not applicable
d
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.
e
When used with Honeywell communicating actuator the damper out is reported in XX.X% open versus XX.X Vd.
f
After 10 minutes without a command or mode change, the controller will change to normal operation.
