Initiation of Operating Modes
The JADE controller is able to initiate the following
modes: Compressor, Economizer, Fans, Heating
System, and Cooling System. The Compressor mode is
initiated by either the OAT going above the DRYBLB
SET setting or by the thermostat initiating a call to cool
when the damper is at 100% open. The Economizer
mode is controlled by the MAT getting above the MAT
SET setting while the OAT is below the DRYBLB SET
setting. While the fans are not controlled by the
controller, the Fan mode is dependent on what state
the system is in (OCC or Y1 states will cause the
damper to go to a LOW fan speed damper setting,
while W state will cause the controller to open the
damper to the HIGH fan speed damper setting). The
Heating System mode requires an input to the AUX2-1
terminal from the thermostat, and the Cooling System
mode requires an input to the Y1 IN terminals from the
thermostat.
Economizer Setup and
Configuration (Field and Factory
Installed Option)
Before being placed into service the controller must be
setup and configured for the installed system.
IIm mp po orrtta an ntt:: During setup, the economizer controller is
live at all times.
1. Using the keypad on the controller scroll through
the Setpoints, System Setup, and Advanced Setup
menus and verify or set/change the parameters.
See
Table 4, p. 10 .
2. Install front filter access panel back on to unit and
secure with previous screws.
N No otte ess::
• The W (heating mode) is not controlled by
the controller but it requires the status to
know where to position the outside air
damper for minimum position for the fan
speed.
• All setpoints and advanced settings are
restored after any power loss or interruption.
