How do I change the temperature unit from Celsius to Fahrenheit?
In the configuration menu, set parameter Unit to 1 for Fahrenheit or 0 for Celsius. The change takes effect immediately.
What is the maximum current rating of the relay output?
The built-in relay is rated for 3 A at 250 V AC (resistive load). For higher loads, use the SSR driver with an external SSR.
How do I lock the front panel keys to prevent tampering?
Set parameter Loc to 1 (full lock) or 2 (partial lock). To unlock, press ▲ + ▼ simultaneously for 3 seconds.
The controller is not responding. What should I check?
