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.

C-599T is a five-period scheduled heating controller, mainly for applications requiring multi-period scheduled temperature-controlled heating.Controls scheduled heating in up to [five time periods] per day, with a separate heating temperature for each period.During scheduled periods, the controller can control the relay output (NO and NC contacts) based on temperature.

BF-D220A+ is widely used in temperature control applications, including hot water, solar, and heat pump systems.

C3-200A+ Upper/Lower-Limit Temperature Controller, widely used in solar and heat pump water heating and various other heating applications. One temperature input uses a BESFUL NTC-220 thermistor with measurement and display accuracy up to 0.1℃, allowing users to monitor temperature trends intuitively;One output controls one relay (NO and NC contacts) for temperature control over a range of 0°C–120°C;Extremely easy to configure: simply adjust the upper and lower limits, and changes take effect immediately. The wide-range power supply automatically adapts to AC80V–240V for stable, reliable, long-term operation.

C-440 provides two independent temperature-control channels, each with a dedicated NTC 10K thermistor sensor for independent temperature measurement and output control;Channel 1 temperature control relay output has NO and NC contacts; Channel 2 has NO contacts.
