- Updated the calculations and added refrigerants

App Description

HVAC mechanics have a new option when it comes to the standard paper pressure-temperature (PT) chart they currently carry. Honeywell offers a colorful display in which users can select a refrigerant and get all of the data they need to perform their tasks in the field. Using the touch screen, users can quickly calculate superheat and subcool averages to set a control from either their iPhone or iPad device.
