Fourtech controllers feature universal inputs. Wire your sensor to the dedicated input terminals according to its specific type:
No system is immune to error, and the Fourtech manual anticipates this reality through a comprehensive troubleshooting guide. This section categorizes common error codes (e.g., sensor burnout, communication failure, output saturation) and provides step-by-step diagnostic procedures.

SSR (Solid State Relay) Output: Delivers a 12V DC pulse to drive an external SSR directly.
Proper installation prevents equipment damage and ensures accurate temperature readings. Always disconnect the power supply before handling the wiring. Wiring Terminal Configuration
Temperature Controller Parameter Setting #PID #Controller with #SSR Sets the maximum temperature threshold before the alarm
Relay Output: Acts as a dry-contact switch to trigger an external contactor.
Always disconnect the power supply before handling terminal connections to avoid electrical shock.
Connects to your primary heating or cooling element actuator.
Depending on your specific hardware configuration, you will use either mechanical relay contacts or a Solid State Relay (SSR) driver.
