6 FACTORY OPTIONS AND/OR ACCESSORIES Economizer (dry- -bulb or enthalpy) Economizers save money. They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low- -ambient cooling. When coupled to CO 2 sensors, Economizers can provide even more savings by coupling the ventilation air to only that amount required. Economizers are available, installed and tested by the factory, with either enthalpy or dry- -bulb temperature inputs. There are also models for electromechanical as well as direct digital controllers. Additional sensors are available as accessories to optimize the economizers. Economizers include gravity controlled, barometric relief equalizes building pressure and ambient air pressures. This can be a cast effective solution to prevent building pressurization. CO2 Sensor Improves productivity and saves money by working with the economizer to intake only the correct amount of outside air for ven tilation. As occupant s fill your building, the CO 2 sensor detects their presence through increasing CO2 levels, and opens the economizer appropriately. When the occupants leave, the CO 2 levels decrease, and the sensor appropriately closes the economizer. This intelligent control of the ventilation air, called Demand Control V entilation (DCV) reduces the overall load on the rooftop, saving money. Smoke Detectors Trust the experts. Smoke detectors make your application safer and your job easier. Carrier smoke detectors immediately shut down the rooftop unit when smoke is detected. They are available, installed by the factory, for supply air, return air, or both. Louvered Hail Guards Sleek, louvered panels protect the condenser coil from hail damage, foreign objects, and incidental contact. Non- -fused Disconnect This OSHA- -compliant, factory- -installed, safety switch allows a service technician to locally secure power to the rooftop. Power Exhaust with Barometric Relief. Superior internal building pressure control. This field- -installed accessory may eliminate the need for costly, external pressure control fans. PremierLinkt This CCN controller regulates your rooftop’s performance to tighter tolerances and expanded limits, as well as facilitates zoning systems and digital accessories. It also unites your Carrier HV AC equipment together on one, coherent CCN network. The PremierLink can be factory- -installed, or easily field- -installed. RTU Open Multi- -protocol Controller Connect the rooftop to an existing BAS without needing complicated translators or adapter modules using the RTU Open controller. This new controller speaks the 4 most common building automation system languages (Bacnet, Modbus, N2, and Lonworks). Use this controller when you have an existing BAS. Time Guard II Control Circuit This accessory protects your co mpressor by preventing short- -cycling in the event of some other failure, prevents the compressor from restarting for 30 seconds after stopping. Not required with PremierLink r,R T UO p e n ,o r authorized commercial thermostats. Filter or Fan Status Switches Use these differential pressure switches to detect a filter clog or indoor fan motor failure. When used in conjunction with a compatible unit controller/thermostat, the switches will activate an alarm to warn the appropriate personnel. Motorized 2- -Position Damper The new Carrier 2- -position, motorized outdoor air damper admits up to 100% outside air. Usin g reliable, gear- -driven technology, the 2- -positio n damper opens to allow ventilation air and closes whe n the rooftop stops, stopping unwanted infiltration. Manual OA Damper Manual outdoor air dampers are an economical way to bring in ventilation air. The dampers are available in 25% and 50% versions. Motormaster Head Pressure Controller The Motormaster motor controller is a low ambient, head pressure controller kit that is designed to maintain the unit’s condenser head pressure during periods of low ambient cooling operation. This device should be used as an alternative to economizer free cooling not when economizer usage is either not appropriate or desired. The Motormaster will either cycle the outdoor- -fan motors or operate them at reduced speed to maintain the unit operation, depending on the model. 50TC
