STC-1000 Digital Temperature Controller – 220V Dual Relay Thermostat, Cooling and Heating

【Simultaneous Connection of Heating and Cooling】Frequent switching of cables between heating and cooling is not required. This sensor-controlled temperature controller is equipped with two relays. Compared to other temperature controllers with only one relay, you can connect two devices (heating and cooling) simultaneously. Please note that no plugs are included; no wiring is necessary. 【Maintaining Temperature in the Desired Range】This is an on/off control mode. The temperature is regulated by setting the temperature controller, and switching between heating and cooling modes is automatic. By fully utilizing the STC microcontroller and NTC sensor, this temperature controller offers the highest precision. 【High Precision】The digital dual-relay thermostat is housed in a robust, flame-retardant ABS plastic casing with an integrated structure, making it safe and energy-efficient. Power consumption: ≤3 W, Temperature control range: -50 °C to 99 °C, Accuracy: ±1 °C, Power supply: 110–220 V
