PROGRAMMING THE JADE W7220
CONTROLLER
The next several pages detail the dierent status displays,
setpoints, setup, and alarms available on the controller. This list
below and Table 10 summarizes the inputs required for a standard
application with a single outside air sensor. NOTE: instead of
setting the SETPOINTS you can use the defaults already set in
the Jade controller – see default settings below. See Table 10 for
summerized standard settings or for more detail see Table 11 –
Menu Structure.
SETPOINTS
‒ MAT SET: this sets the mixed air temperature (MAT) setting.
The controller has a default of 53 degrees, but the range is
anywhere from 38 to 70 degrees F.
‒ LOW T LOCK: This setting locks out the compressor (or
mechanical cooling) at a given temperature. The default is 32
degrees F, but the controller’s range is from -45 to 80 degrees
F.
‒ DRYBULB SET: if you have an economizer with a dry bulb
outside air sensor you will see and set the DRYBULB SET. The
default setting is 63 degrees F but the controller’s range is 48
to 80 degrees F.
‒ ENTH CURVE: if you have a single enthalpy outside air sensor
instead of a dry bulb, you will see and set the ENTH CURVE
setting. There are 5 setting options: ES1 thru ES5. Check the
economizer literature for the limits for each of these settings.
ES3 is the default setting.
SYSTEM SETUP
‒ INSTALL: Allows you to set the current date. Use the keypad
buttons to scroll to the correct date.
‒ EQUIPMENT: Always set to CONV even if the unit is a heat
pump.
‒ AUX2 IN: Always set to W1.
‒ FAN TYPE: Set for either single or 2 speed. The default is 2
speed.
‒ AUX1 OUT: If remote Fault Detection and Diagnostic (FDD)
monitoring is required select SYS.
‒ OCC: occupancy, always set to INPUT
‒ MIN POS: The minimum position allows for ventilation even
when not in the free-cooling mode. If you have a single speed
unit there will be only one minimum position setting. The
default is 2.8 volts, but the range is 2-10Vdc.
o MIN POS H and MIN POS L: If your unit is 2 speed, there
will be 2 minimum position settings that show up on the menu.
The rst is MIN POS H (for high speed) which has a default of
2.8 volts. The second is MIN POS L (for low speed), which has
a default of 3.2. Note that MIN POS H and MIN POS L are only
displayed if under SYSTEM SETUP: AUX2 IN is set to “W1”,
and FAN TYPE is set to 2 speed.
