Temperature Controller

The FY-WK(TH) is a fundamental temperature controller developed for maintaining safe operating temperatures inside electrical enclosures. It continuously monitors the ambient temperature using its built-in sensor and displays the current value on a digital indicator (if equipped).

When the temperature rises above the preset upper limit, the controller activates the connected cooling fan to reduce heat. When the temperature drops below the preset lower limit, it activates the connected heater to prevent condensation. Once the temperature returns to the normal range, the controller automatically deactivates the output.
