Menu Structure

Table 11 illustrates the complete hierarchy of menus and parameters for the Economizer system.
The Menus in display order are:
• STATUS
• SETPOINTS
• SYSTEM SETUP
• ADVANCED SETUP
• CHECKOUT
• ALARMS
Programming the JADE W7220 Controller
The next several pages detail the different status displays, setpoints, setup, and alarms available on the controller. This list below and Table
4 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 7 for summarized standard settings or for
more detail see Table 8 – Menu Structure.
Setpoints
• MAT SET: This sets the mixed air temperature (MAT) setting. The controller has a default of 53°, but the range is anywhere from 38°F to
70°F.
• LOW T LOCK: This setting locks out the compressor (or mechanical cooling) at a given temperature. The default is 32°F, but the controller's
range is from -45°F to +80°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°F to 80°F.
• ENTH CURVE: If there is a single enthalpy outside air sensor instead of a dry bulb, see and set the ENTH CURVE setting. There are five
(5) setting options: ES1 thru ES5. Check the economizer literature for the limits for each of these settings. ES3 is the default setting.
• MIN POS: The minimum position allows for ventilation even when not in the free-cooling mode. If there is a single speed unit, there will be
only one minimum position setting. The default is 2.8 volts, but the range is 2-10Vdc.
System Setup
• INSTALL: Allows setting of 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
