KT8230 °F/℃ Temperature Controller

The KT8230 Temperature Controller offers a wide range of features suitable for various applications. It supports temperature control from -22°F to 572°F (-30℃ to 300℃) and features a robust 30A relay output for controlling high-power devices such as incubators, refrigerators, fermenters, and greenhouses with precision down to ±1°F.

Features and Modes

Heating and Cooling Modes: - Cooling Mode: Activates when the measured temperature is above the set temperature plus the differential. - Heating Mode: Activates when the measured temperature falls below the set temperature minus the differential.

Applications

The KT8230 is versatile and can be used in various settings including: - Domestic freezers - Refrigerators - Industrial chillers - Steamers - Other industrial equipment requiring temperature regulation.

Error Codes

• EE1: Sensor fault. Check sensor for damage or poor contact.
• HH1: High temperature alarm. Activates when the measured temperature exceeds the upper limit.
• LL1: Low temperature alarm. Activates when the measured temperature falls below the lower limit.

2-Wire Connection

FAQs:

Q: Why is there no output voltage? A: The KT8230 is a relay temperature controller and does not provide direct voltage output. You need to connect an additional power supply to the load for it to function as a switch.

Q: How can I calibrate the temperature if there's an error? A: Press the SET button for 3 seconds in normal operating mode to enter parameter setting mode. Navigate to the CA code (-30.0°F to 30.0°F / -7℃ to 7℃) using the UP or DOWN buttons for temperature calibration.

Q: Why doesn't it turn off the device as set? A: Ensure that the PL (delay start time) is set to 0. If PL ≠ 0, the display will flash, indicating that the cooler or heater will only activate after the programmed delay time.

Q: Why can't I set a temperature beyond the specified range of -22~572℉ / -30~300℃? A: Adjust the HS (high limit) and LS (low limit) settings. For instance, setting HS = +60 and LS = -10 limits the temperature range to -10℃ to +60℃. Modify these settings to extend beyond the default range.
