Reference information in the attached FHMT spreadsheet.
The attached VOP Readings TWIN 9 13.xlsx workbook contains an FHMT worksheet headed Tempzone Twin 120V and 15 W/sq. ft. technical data. It lists mat area and dimensions, wattage, cable length in meters and feet, resistance in ohms, current in amps, and VOP/SS cable-length columns.
For example, its 1.5 × 4 ft, 6 sq. ft. row lists 90 W, 22.98 ft of cable, 160 Ω and 0.75 A. These are values from that historical workbook, not specifications for every current TempZone product.
For installation or resistance testing, identify the actual mat and compare readings with its factory label and applicable manual. Do not substitute a nearby spreadsheet row for the label or apply the workbook to 240 V products. The workbook does not define a complete fault-location procedure or a universal VOP setting.
