Frequently Asked Questions

Q: What sensor types are compatible with the TC Series PID temperature controller?

A: The TC Series controller is compatible with a wide range of sensors. Thermocouple types supported include K, J, R, S, B, E, N, T, W4Re/W26Re, and PLII. It also works with RTD sensors Pt100 and JPt100, making it highly versatile for diverse industrial and lab temperature control applications.

Q: What is the difference between PID and ON/OFF control mode on this thermostat?

A: PID (Proportional-Integral-Derivative) control continuously calculates and adjusts the output to maintain the target temperature with minimal overshoot — ideal for precise process control. ON/OFF mode simply switches the output fully on or off when the temperature crosses the set point, which suits simpler applications where tight precision is less critical.

Q: Can this temperature controller be used with both 110V and 220V power supplies?

A: Yes. The TC Series PID digital thermostat accepts a supply voltage of AC 100–240V, making it fully compatible with both 110VAC and 220VAC electrical systems worldwide.

Q: Which model size should I choose for my panel installation?

A: Choose based on your panel cutout dimensions: TC4S fits a 45×45mm cutout, TC4H fits 45×92mm, TC4M fits 68×68mm, and TC4L fits 92×92mm. All models share the same 75mm depth behind the panel.
