4.2 Setting Differential

The differential setting determines the pressure difference between the cut-in and cut-out points. Adjust this setting as required for your application, typically found near the main setpoint adjustment.

5. Manutenzjoni

The Danfoss RT-112 is designed for minimal maintenance. Regular inspections are recommended to ensure optimal performance and longevity.

Spezzjoni Viżwali: Periodically check for any signs of physical damage, corrosion, or leaks around the pressure connection.
Integrità tal-Konnessjoni: Ensure all electrical and pressure connections remain tight and secure.
Tindif: Keep the exterior of the unit clean and free from dust or debris. Do not use abrasive cleaners.
Kontroll tal-Kalibrazzjoni: If precise pressure control is critical, periodically verify the switch's setpoint accuracy using a calibrated pressure gauge.
