Ranco support FAQ

Preguntas frecuentes sobre manuais, rexistro e asistencia técnica para esta marca.

  • How do I change the temperature scale to Celsius on a Ranco ETC control?

    To switch between Fahrenheit and Celsius, press the SET key once to access the scale mode. The display will show the current status (F or C). Use the up or down arrow keys to toggle the selection.

  • What does the E1 error message mean on my Ranco controller?

    An E1 error message typically appears if the up or down key is pressed when the unit is not in programming mode. If the message appears constantly without any keys being pressed, the control may need replacement.

  • How do I reset a Ranco pressure control with a manual reset?

    For manual reset controls (such as the O16 series), the system pressure must return to a safe operating range before the device can be reset. For low-pressure controls, pressure must rise approximately 10 PSIG above the cut-out setting; for high-pressure controls, it must drop approximately 40 PSIG below the cut-out setting.

  • What is the E2 error on a Ranco thermostat?

    The E2 error indicates that control settings are not properly stored in the memory. To correct this, check all programming settings and save them again consistent with your application requirements.

  • Are Ranco ETC controls water resistant?

    Many Ranco ETC models, such as those with NEMA Type 4X enclosures, are rated watertight and are suitable for outdoor use or high-moisture environments like agricultural buildings.
