Will this work with my system?

Match your equipment to these requirements before ordering.

Works with

  • Walk-in coolers and commercial refrigeration applications requiring a remote temperature display and illuminated light switch.

System requirements

  • 110 VAC supply for power code 4.
  • Fahrenheit measurement range -40 to 230°F; one-second display update.
  • Provide a suitable switch-plate mounting location and sensor routing; compare the installed sensor arrangement with the standard detachable 5 ft sensor.

Limitations & exclusions

  • Temperature indication does not provide a thermostat heating/cooling control output.
  • The 12 V and 230 V family power options are different order codes.

Check before you buy

  1. Read all code fields: L = lighted-switch plate; 4 = 110 VAC; F = -40 to 230°F; 0 = one-second update.
  2. Compare the supply, sensor reach, mounting arrangement, and lighting circuit with the equipment requirements; the datasheet lists a 15 A light switch without a load-class qualification.

Overview

The Weiss Instruments 24DT-L-4F0 combines a remote LED thermometer with an illuminated light switch on a switch plate. Weiss is a DwyerOmega brand. This configuration is intended for temperature indication and lighting access in walk-in coolers and other commercial refrigeration applications.

Exact configuration

The ordering table identifies L as the lighted-switch plate, 4 as 110 VAC power, F as the -40 to 230°F range, and the final 0 as a one-second update. The standard sensor is detachable with a 5 ft lead. A 9 V battery-backup harness and longer sensor lengths are optional family accessories, not confirmed package contents.

Selection considerations

Compare the entire order code and supply with the installation. The temperature range belongs to the measured temperature; it is not an ambient operating rating. The unit displays temperature and switches lighting; it should not be selected as a replacement refrigeration temperature controller.
