ZL-6210A+ Digital Thermostat Temperature Controller Switch — 30A Output, Dual-Relay, °C/°F

The ZL-6210A+ is a straightforward digital temperature controller with a 30A output, designed to manage heating and refrigeration systems. It supports display in either °C or °F and features dual-relay operation to drive cooling and heating equipment, switching between them automatically as conditions change. Temperature is regulated by setting a desired set value and an adjustable differential. Built-in safety alerts sound if the temperature exceeds preset limits or if a sensor fault occurs. You can also configure temperature parameters and a compressor delay to protect your refrigeration/heating gear and extend component life.
