JADE™ ECONOMIZER MODULE

SPECIFICATIONS

W7220A Economizer Module
The module is designed for use with any Honeywell 2 to 10
Vdc or Honeywell Sylkbus communicating actuator. The
module includes terminals for a CO
and an Outdoor Dry Bulb sensor. Enthalpy and other options
are available with Sylk Bus sensors.
User Interface: Provides status for normal operation, setup
parameters, checkout tests, and alarms and error
conditions with a 2-line 16 character LCD display and a four
button keypad.
Electrical
Rated Voltage: 20 to 30 Vac RMS; 50/60 Hz
Nominal Power Consumption (at 24 Vac, 60 Hz): 11.5 VA
without sensors and actuator
Relay Contact Rating at 30 Vac (maximum power from
Class 2 input only): 1.5A run;
3.5A inrush @ 0.45PF (200,000 cycles) or
7.5A inrush @ 0.45PF (100,000 cycles)
External Sensors Power Output: 21 Vdc +/- 5% @ 48mA
IMPORTANT
All inputs and outputs must be Class 2 wiring.
Inputs
SENSORS:
NOTE: A Mixed air (MA) analog sensor is required on all
W7220 units; either an OA (Outdoor Air) sensor for
dry bulb change over or an OA Sylkbus sensor for
outdoor enthalpy change over is required in addition
to the MA sensor. An additional Return Air (RA)
Sylkbus sensor can be added to the system for
differential enthalpy changeover.
Dry Bulb Temperature and Mixed Air, C7250A:
2-wire (18 to 22 AWG);
Temperature range -40 to 150 °F (-40 to 65 °C).
Temperature and Humidity, C7400S1000 (optional):
Sylk Bus; 2-wire (18 to 22 AWG)
Temperature: range -40 to 150 °F (-40 to 65 °C)
Humidity: range 0 to 100% RH with 5% accuracy.
NOTE: Up to three (3) SYLK Bus sensors may be connected
to the JADE™ Economizer module.
DCV (CO ) Sensor (C7232):
