RT-SVX50F-EN
programmable, wall-mounted thermostat, and it can be
used for economizer operation.
CO
2
Sensor
This optional sensor can be added for Demand Control
Ventilation (DCV) functionality.
On units with a low leak economizer, configure the JADE
controller by setting the following parameters:
SETPOINTS Menu:
DCV SET = desired CO
2
ppm to start DCV
VENTMAX = desired maximum position w/DCV &
occupied status (2-speed applications require LO & HI
settings)
VENTMIN = desired minimum position w/DCV & occupied
status (2-speed applications require LO & HI settings)
ADVANCED SETUP Menu:
CO2 ZERO = set to detector's start level
CO2 SPAN = detector's max level minus start level
Attach the sensor to the CO
2
and "R" terminals (at
customer connections).
Note:
When using any 0-10 Vdc CO
2
sensor with the JADE
you will need to set CO2 ZERO to 400 ppm and the
CO2 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.
Low Leak Economizer Units
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.
Initiation of Operating Modes -
JADE Controller
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 Y2 or W
states 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 Y2 IN and/or the Y1 IN terminals from the
thermostat.
