Ketotek STC-1000 Temperature Controller

What should I do if the screen displays 'Er.' when I power on the device?

The 'Er.' display indicates that an error has been detected during the system's self-check on startup. Press any key to restore the default values and enter normal working mode. It is advisable to reset the parameter values under this condition.

How do I enter parameter setting mode on the STC-1000?

In normal working status, press the 'S' button for 3 seconds to enter the parameter setting mode. You can then use the designated buttons to navigate through the menu codes (F1 to F4) and adjust the parameter values as needed.

What happens if I don't save my parameter changes within a certain time?

If no key operation occurs within 30 seconds after making parameter changes, the system will not save the modified parameters, and the screen will revert to displaying the normal temperature. You must press and release the back button to save changes before the 30-second timeout.

How does the heating mode work on this temperature controller?

Heating starts when the real-time temperature (RT) is less than or equal to the set temperature (ST) minus the difference value (F2), and the heating indicator light turns on. When RT ≥ ST, the heating indicator turns off and the heating relay disconnects, stopping the heater.

What is the refrigerating control output delay protection feature?

This feature prevents compressor damage by introducing a delay before the cooling output is activated, allowing the system to stabilize. During this protection period, the cooling indicator light will flash to indicate that the refrigerating equipment is under compressor delay protection.

What temperature control range does the STC-1000 support?

The Ketotek STC-1000 supports a temperature control range of -50~99°C with an accuracy of ±1°C for temperatures between -50°C to 70°C. The resolution is 0.1°C.
