Lennox Prodigy vs CaptiveAire Toolbox

The most intelligent rooftop unit control system now has tools on the go. The Lennox Prodigy® Control System is now accompanied by the Lennox Prodigy app providing immediate access to valuable technical information to help you save time and money on service calls. Whether you need videos that show how the Lennox Prodigy Control System is operated in different modes, or access to FAQs and technical literature, the Lennox Prodigy app provides a single source for all of your needs. Troubleshooting guides and a searchable list of configuration parameters minimize your need for any printed materials at the job site. With the Prodigy app, you will now be able to: -Watch how-to videos -Access Prodigy related technical literature -Review alarm lookup tables with step by step troubleshooting guide -Search a list of configuration parameters with detailed description -Visit Frequently Asked Questions Note that this app will not directly connect to the Lennox Prodigy Control System. The app is a central database of technical, service, installation, and troubleshooting guides.

The CaptiveAire Toolbox puts 40+ HVAC and building-systems engineering calculators in your pocket. Designed for engineers, contractors, and technicians, every formula uses standard industry references (ASHRAE, AMCA, NEC), sized so you can run sanity checks in the field instead of pulling out a laptop. Cooling: Total Cooling Load (enthalpy-based with humidity), Sensible Cooling Load, Latent Cooling Load, SEER, Cost of Cooling, Tons to BTU/hr conversions, DX/MPU Cooling, Evaporative Cooling, DMUA mode logic, Cooling Density Factor. Heating: BTU output for direct and indirect fired heaters, Input and Output BTU/hr for IBT systems, Temperature Rise from BTU and CFM, Heat Pump capacity with airflow and outdoor temperature adjustment, Reheat Coil leaving conditions, Manifold Pressure for natural gas and LP, Heating Density Factor. Ventilation and Airflow: Room Volume CFM, Sensible Heat CFM, Cooling Load CFM, Duct Velocity CFM, Outdoor Air Load (sensible plus latent), Psychrometric properties from dry bulb plus RH or wet bulb, Fan Energy Index per AMCA 208, Motor Adjusted Frequency for VFDs, ERV ROI Calculator with degree-day economics. Electrical Sizing: Wire Size per NEC Table, MCA and MOCP for motor circuits, Amperage from horsepower. Piping and Structural: Round Duct Sizing using Darcy-Weisbach and Colebrook-White, Duct Velocity and Friction, Piping Pressure Drop with fittings equivalent length, Pitched Roof curb height variation. Valve and Flow Sizing: Kv from flow rate, flow rate from Kv, pressure drop from Kv, Cv to Kv conversion, Heat Load to Flow Rate for water and glycol. Reference: ASHRAE Weather Station data with autocomplete address search, returning heating and cooling design temperatures, solar irradiance, wind speeds, and monthly design-day temperatures.
