Features & Capabilities

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.

User Reviews

User reviews largely reflect a regression after the latest update. Common issues include the app crashing or failing to open (including on iPhone X), difficulties with selecting/searching refrigerants, and the PT chart not displaying temperatures or readings. Several users report subcooling and superheat calculations no longer work, and some want the chart to show pressures and temperatures. While quick SC/SH calculations were valued, overall feedback calls for a rollback or major bug fixes and data enhancements.

Pros

Useful for quick calculations of subcooling and superheat (SC & SH).
Historically reliable/good performance prior to the latest update.

Cons

App crashes or wont open after the latest update (reports of instant crashes on various devices).
Difficulties with refrigerant search/selection, with some users noting crashes when trying to select a refrigerant.
PT chart lacks temperatures/readings or fails to display data (missing temps/readings on the chart).
Subcooling and superheat calculations no longer work after the update (calculation features broken).

Recent reviews

Need updated refrigerants including A2L.

Great update. App shuts off now every time I have to try to select a refrigerant. Worked fine before the update. Oh well, pt charts aren't hard to find
