VENTMAX = desired maximum position w/DCV &
occupied status
VENTMIN = desired minimum position w/DCV &
occupied status
ADVANCED SETUP Menu:
CO
2
ZERO = set to detector's start level
CO
2
SPAN = detector's max level minus start level
Attach the sensor to the CO
2
and “R” terminals (at
customer connections).
N No otte e:: When using any 0-10 Vdc CO
2
sensor with the
JADE you will need to set CO
2
ZERO to 400 ppm
and the CO
2
SPAN to 1600 ppm in the
ADVANCED SETUP menu.
Occupancy Sensor
A customer-supplied occupancy sensor can also be
added to provide damper control based on occupied/
unoccupied conditions. To configure the JADE
controller, set:
SYSTEM SETUP menu: OCC = INPUT
Attach the occupancy sensor to the OCC SENSOR wire
and “R” terminal (at customer connections). The
occupancy sensor must utilize a normally open contact
for proper operation.
If an occupancy sensor is not used, another option to
controlling occupied and unoccupied status is to use
the 'G' input (fan is running). Connect the G input to the
OCC SENSOR wire (at customer connections). The
controller will then operate in the occupied mode every
time the indoor fan is running.

Inspect all wiring connections at the Economizer
module’s terminals, and verify compliance with the
installation wiring diagrams.
For checkout, review the status of each configured
parameter and perform the checkout tests.
Power Up
After the module is mounted and wired, apply power.
Power Up Delay
Upon power up (or after a power outage or brownout),
the controller module begins a 5 minute power up
delay before enabling mechanical cooling.
Initial Menu Display
On initial start up, “Honeywell” displays on the first
line and “Economizer W7220” on the second line. After
a brief pause, the revision of the software appears on
the first line and the second line will be blank.
Power Loss
All setpoints and advanced settings are restored after
any power loss or interruption.
N No otte e:: If power goes below 18 Vac, the controller
module assumes a power loss and the 5 minute
power up delay will become functional when
power returns above 18 Vac.
Status
Use the Status menu (see Table 4, p. 10 ) to check the
parameter values for the various devices and sensors
configured.
N No otte e:: See “Controller User Interface and Keypad,” p. 8
for information about menu navigation and use
of the keypad.

items that are configured are shown in the Checkout
menu.
To perform checkout tests:
1. Scroll to the desired test in the Checkout menu
using the ∆ and ∇ buttons.
2. Press the button to select the item.
3. “RUN?” is displayed.
4. Press to start the test.
5. The unit pauses and then displays “IN PROGRESS”.
6. When the test is complete, “DONE” appears.
7. When all parameters have been tested, press
(Menu Up) to end the test (e.g. turn off the relay).
