Shows the Derating Value from the altitudeselected on the Info Page

Clickable option to select the type ofoperation the unit will be used for.In this example we have selected

Heating & Cooling.

With the proper amount of vents inputtedThe vent check will approve

With too long of flex runs the vent check fails on Bedrm 2. A branch plenum should berun to shorten the flex runs, or a different

configuration of flex runs tried.

Clickable option to select type ofInsulation used on the flex.

Heating and Cooling requiredfor both areas

Units required for minimumHeating and Cooling

Clickable drop down Fancoil selection menus, here were selecting the

HV-70 to meet the minimum cooling requirements for Area 1.

A/B/C – Additional input boxes for vents in unconditioned spaces.

Information box showing how many vents have been placed in all areas, and how much extension flex is used.

Information box showing• Minimum number of vents allowed.• Total of number vents placed in all areas.• Maximum number of vents allowed before degrading system performance.• If the number of vents placed is incorrect Vents placed will disagree

to the design with a N.
