Product Data WeatherMaker® Single Packaged Rooftop Heat Pump Units 6 to 12.5 Nominal Tons 50TCQ*07, 08, 12, 14 Electric Cooling Rooftop Units with Heat Pump and Optional Electric Heat with Puron® (R-410A) Refrigerant © 2019 Carrier Corporation Form 50TCQ-7-14-02PD

Features/Benefits The Carrier Packaged Heat Pump rooftop unit (RTU) was designed by customers for customers. With no-strip screw collars, handled access panels, and more, we’ve made your unit easy to install, easy to maintain and easy to use. Easy to install All WeatherMaker® units are field-convertible to horizontal air flow which makes it easy to adjust to unexpected job site complications. Lighter units make easy replacement. Carrier 6 to 12.5 ton 50TCQ rooftops fit on existing Carrier curbs dating back to 1989. Also, our large control box gives you room to work and room to mount Carrier...

Model number nomenclature Staged Air Volume (SAV™) fan speed system utilizes a Variable Frequency Drive (VFD) to automatically adjust the indoor fan motor speed between cooling stages. Available on single stage cooling model 07 and 2-stage cooling models, 08-14 with electro-mechanical controls or RTU Open controller. Note that SAV is required on all units for installation in the United States as per the Department of Energy (DOE) efficiency standard of 2018. Series - WeatherMaker® 50TC - Packaged Rooftop Refrig. Systems Options A = One Stage Cooling Models D = Two Stage Cooling Models...

MINIMUM - MAXIMUM AIRFLOWS (CFM) COOLING AND ELECTRIC HEAT 50TCQ UNIT ‘Minimum electric heat CFM exceptions (see table below): LEGEND dB — Decibel NOTES: 1. Outdoor sound data is measured in accordance with AHRI standard 270. 2. Measurements are expressed in terms of sound power. Do not compare these values to sound pressure values because sound pressure accounts for specific environmental factors which do not match individual applications. Sound power values are independent of the environment and therefore more accurate. A-weighted sound ratings filter out very high and very low...

Power Exhaust Pressure Relief Economizers can reduce operating costs. 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 CO2 sensors, economizers can limit 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 electro-mechanical as well as direct digital controllers. Additional sensors are available as accessories to optimize the...

IMPORTANT: Data based on 0.10 ($/kWh) in an office application utilizing Carrier’s HAP 4.6 simulation software program. Compared to single speed indoor fan motor systems, Carrier’s SAV system can save substantial energy, 25%+, versus single speed indoor fan motor systems. The VFD used in Carrier’s SAV system has soft start capabilities to slowly ramp up the speeds, thus eliminating any high inrush air volume during initial start-up. It also has internal over current protection for the fan motor and a field-installed display kit that allows adjustment and in depth diagnostics of the VFD....
