controller?\u003c\/h4\u003e\n\u003cp\u003eA: The E5C4 thermostat supports both \u003cstrong\u003eK Type thermocouples\u003c\/strong\u003e and \u003cstrong\u003ePT100 RTD sensors\u003c\/strong\u003e. K Type sensors are commonly used for higher-temperature industrial applications, while PT100 RTDs offer slightly higher precision at lower temperature ranges. Choose the model variant that matches your existing sensor infrastructure.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum temperature range this controller can handle?\u003c\/h4\u003e\n\u003cp\u003eA: The E5C4 model covers a measurement and control range of \u003cstrong\u003e0–399°C\u003c\/strong\u003e. The E5C2 variant extends this range up to \u003cstrong\u003e0–999°C\u003c\/strong\u003e. Both models feature the same dial-code adjustment method and LCD digital display, making them easy to configure for your specific process temperature requirements.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I install the E5C4 thermostat into my panel?\u003c\/h4\u003e\n\u003cp\u003eA: The controller is designed for standard \u003cstrong\u003e45×45mm panel cutout\u003c\/strong\u003e mounting. Simply cut the appropriate opening in your enclosure, slide the unit in from the front, and secure it with the included socket base at the rear. The relay output connects directly to your heating or cooling element. No advanced tools are required for a standard installation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this controller suitable for home use or is it industrial only?\u003c\/h4\u003e\n\u003cp\u003eA: While the E5C4 is primarily designed for \u003cstrong\u003eindustrial and workshop applications\u003c\/strong\u003e — including food ovens, greenhouses, fermentation chambers, and plastic machinery — it can also be used in well-ventilated home workshop or hobbyist setups where a 220VAC power supply is available.
