KT-2X series thermostats are specially developed for direct cooling refrigerators and freezers; Turn the knob to set the temperature, suitable for all ages.
Short Description
KT-2X series thermostats are specially developed for direct cooling refrigerators and freezers; The function of adjusting the target temperature can be achieved through the rotary knob; the operation is convenient and fast, suitable for all ages, and the performance is stable and reliable.
This serial includes functions such as temperature display, temperature control, compressor start-up delay protection, sensor fault code display, etc.; they are widely used in commercial refrigeration equipment, HVAC, and other industries.
This microcomputer controller determines whether to power the compressor by comparing two temperature parameters. One parameter is the target temperature corresponding to the user’s knob position, and the other parameter is the instantaneous temperature measured by the sensor.

FAQ
What conditions need to be met for the compressor to start?
The following two conditions must be met:
- Time condition: The compressor is shut down for more than 3 minutes.
- Temperature condition: The temperature detected by the sensor is 3 degrees higher than the set temperature (3 degrees is the hysteresis value); for example, if you turn the knob to level 5 on the KT-213, the corresponding target temperature is 2 degrees, and the compressor will start when the temperature is higher than 2+3=5 degrees.
What does EEE mean?
EEE means that the sensor is faulty. At this time, you can try to reinstall the sensor. If the problem still cannot be solved, then you should replace it with a new sensor.
How to install it?
- Open a rectangular hole in the panel of the freezer. Its size should be 112*39mm
- According to the wiring diagram, pass the power bus compressor wires, and sensor wires through this hole and connect them to the controller.
- Ensure everything is working well after powering on, plug the thermostat into the hole, and the buckle behind the front panel will automatically fix it.
