ECONOMI$ER ® X (FACTORY-INSTALLED OPTION)
Product Description — The EconoMi$er X system is an ex-
pandable economizer control system, which includes a W7220
economizer module (controller) with an LCD and keypad (see
Fig. 36). The W7220 can be configured with optional sensors.
Fig. 36 — W7220 Economizer Module
The W7220 economizer module can be used as a stand-
alone economizer module wired directly to a commercial set-
back space thermostat and sensors to provide outside air dry-
bulb economizer control.
Economizer Module — The economizer module is the core of
the EconoMi$er X system. The module is mounted in the unit's
control box, and includes the user interface for the system. The
W7220 economizer module provides the basic inputs and out-
puts to provide simple economizer control. When used with the
optional sensors, the economizer module provides more ad-
vanced economizer functionality.
S-Bus Enthalpy Control Sensors — This sensor is a combina-
tion temperature and humidity sensor which is powered by and

Specifications
W7220 Economizer Module — The module is designed for
use with 2 to 10 Vdc or bus communicating actuator. The mod-
ule includes terminals for CO2 sensor, mixed air sensor, and an
outdoor dry bulb sensor. Enthalpy and other options are avail-
able with bus sensors.
User Interface — Provides status for normal operation, setup
parameters, checkout tests, and alarm and error conditions with
a 2-line 16 character LCD display and four button keypad.
