Description
The Honeywell Wall Mount Temperature Sensor – Non Linear (e.g. C7772A1012, TR21-A) is a direct-wired, non-linear NTC wall sensor compatible with Spyder, Excel, and Excel 10 controllers. Available in temperature-only or combined temperature-and-humidity models, with a 20K ohm NTC space sensor on most models (10K ohm variants also available), and an override button with LED. Low-profile flush wall mounting design, roughly 2-3/4″ wide by 4-1/2″ high, with shielded cable connection. Operating temperature range typically 45 to 99°F. Unlike averaging or linearized sensor variants, this non-linear NTC type is matched specifically to controllers programmed for its native resistance curve.
