the end of the manual, before attempting installation.

1.0 General
The KOBOLD TDD Series is a solid state, electronic temperature switch which employs

a Pt-100 R TD as the heart of the sensing system. The measuring p robe and hou sing ar e
constructed of 316L stainless steel providing excellent corrosion resistance. The TDD’s
microprocessor based electr onics allow the user to program a setpoint, adjust switching
hysteresis, dampening and switch logic. There is virtually no calibration drift over its
service life.

In addition to the switch output, t he TDD has a d i g ital display for local indicati on of
temperature.
