T775A2009

The T775A/B/M installation instructions describe stand-alone electronic controllers for remote temperature sensing, with switched and/or proportional outputs. The sheet says each T775A/B/M controller is an operating control, not a limit or safety control, and that a separate safety or limit device is required when the application needs one. A note says all models include a digital input for a disable or setback option.

Table 1 lists T775A2009 as the standard model that replaces T775A1001. That row shows 1 SPDT relay output, no analog output, no floating output, 1 sensor input, 1 sensor included, and a NEMA 1 enclosure. This page already describes the controller as having 1 temperature input, 1 SPDT relay, and 1 sensor included. Other rows in the same table are different models, including NEMA 4X enclosures and modulating outputs of 4-20 mA, 0-10 Vdc, 2-10 Vdc, or Series 90 on the modulating versions. Those other rows are not the T775A2009 configuration.
