Product Details
The C-220 dual-output temperature controller accepts one 10K thermistor temperature input, with measurement and display accuracy up to 0.1℃ for intuitive monitoring of temperature trends.
One input and two outputs independently control two relays for constant-temperature control (for example, output 1 heats the tank water, while output 2 controls a water solenoid valve for constant-temperature water supply).
Powered by a switching power supply with a wide AC80～240V input range, it is suitable for various temperature-control applications, including solar and other hot-water systems and heat-pump hot-water systems.
