ECONOMIZER FEATURES
•
One piece construction—easy to install.
•
Exhaust air damper—built in with positive closed
position. Provides exhaust air capability to prevent
pressurization of tight buildings.
•
JADE
™ controller provides nearly limitless
customization on a solid, intuitive electronic
platform.
•
Actuator Motor – 24 volt, power-open, spring-
return, direct-coupled with stall protection. Self-
centering shaft clamp and access cover facilitate
ease of replacement/maintenance.
•
Proportioning-type control for maximum “free”
cooling economy and comfort with up to 100%
outside air.
•
Enthalpy sensor to monitor outdoor air conditions.
•
Minimum Ventilation Position available for required
ventilation of occupants or dilution of pollutants.
•
Mixed air sensor to monitor outdoor and return air
to automatically modulate damper position.
