Selection & installation notes
- The source explicitly says part of its naming explanation is inferred. Its 1K model rows list both 1 K and 3 K differential. Confirm the exact switching differential and full part number before ordering.
- Select contacts according to the heating/cooling terminal diagram and observe the applicable AC load category or DC power limit. Confirm inductive-load suitability for the actual load.
- The mechanical thermostat does not require a separate sensor supply; confirm any LED/compensation wiring requirements from the exact model diagram.
- Install where air temperature is representative, away from direct hot or cold airflow. Adjust the dial gently and allow wiring access.
- Use inside an appropriately protected enclosure. The product is not explosion-proof. Isolate power before wiring or inspection.
