Bryant 551B Light Commercial Thermidistat, Time Guard Control, Durablade Economizer, Economi$Er

OPTIONS AND ACCESSORIES (cont)

LIGHT COMMERCIAL THERMIDISTAT

Field-installed, wall-mounted device combines temperature and humidity control in one device. The dehumidifier output is used to control the Perfect Humidity dehumidification package. The occu- pied space humidity has a set point range between 50% and 90% relative humidity and provides constant fan operation in occupied mode.

TIME GUARD® CONTROL

Time Guard II Control automatically prevents compressor from restarting for at least 5 minutes after a shutdown. Accessory pre- vents short cycling of compressor if thermostat is changed rapidly. Time Guard II control mounts in the control compartment of unit.

DURABLADE ECONOMIZER

Exclusive Durablade economizer damper design saves energy while providing economical and reliable cooling. A sliding plate on the face of the economizer controls the amount of outdoor air entering the system. When the sliding plate is closed, it provides a leakproof seal which prevents ambient air from seeping in or conditioned air from seeping out. It can be easily adjusted for 100% outdoor air or any proportions of mixed air. Design includes standard dry-bulb control and 30% barometric relief capability.

BRYANT COMMERCIAL THERMOSTAT

Designed specifically for use with Bryant commercial systems, this Bryant programmable thermostat features LED occupied/ unoccupied displays and setback mode which can override continu- ous fan operation.
