Accusensor economizer controls help provide efficient, economical economizer operation. The Accusensor I dry-bulb sensor measures out- door temperature and is standard with the Durablade economizer.

The accessory Accusensor II solid-state enthalpy control senses both dry and wet bulb of the outdoor air to provide an accurate enthalpy read- ing. Accusensor II control is available as a field-installed accessory for the Durablade economizer.

The accessory Accusensor III differential enthalpy sensor control com- pares outdoor temperature and humidity to return-air temperature and humidity and determines the most economical mixture of air. Accu- sensor III is available for Durablade economizers.

BRYANT COMMERCIAL PROGRAMMABLE THERMOSTAT

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

BRYANT LIGHT COMMERCIAL THERMIDISTAT

The light commercial thermidistat combines temperature and dehumidifica- tion control in one device and provides continuous fan operation in occupied mode. Recommended for use with the Perfect Humidity™ package.
