Logic Modules

Using sensors and actuators, Honeywell's Solid State Economizer Logic Modules determine whether Free-Cooling can be used by bringing in outdoor air instead of energizing a compressor. Some Logic Modules, control based upon DCV, using a CO2 sensor.

JADE economizers are the perfect examples of Honeywell innovation that makes saving energy easier for your customers. For buildings with less than 50,000 sq ft and standalone rooftop unit (RTU) applications, JADE is the best solution for a fresh air ventilation system. JADE Fresh Air Economizers with integrated demand control ventilation (DCV) systems are compatible with most individually packaged rooftop or built-up air handling units.
