Dual Relay Thermostat Cooling and Heating STC-1000 Digital Temperature Controller with Waterproof Probe 220V <p>【Connect the heater and cooler at the same time】No need to frequently change the wiring between the heater and the cooler. This temperature controller with sensor has 2 relays. Compared to other temperature controllers with 1 relay, you can wire 2 devices (heating and cooling) at the same time. Please note that there are no sockets, wiring required.</p> <p>【Keep the temperature within the desired range】It is the on/off control mode. Control the temperature by adjusting the temperature setting and the difference, the heating and cooling mode can be automatically switched. Make full use of the STC microcontroller and NTC probe to make this temperature controller have high accuracy.</p> <p>【High precision】Made of a sturdy and anti-flame ABS plastic shell with integrated structure, this dual relay digital thermostat is safe and energy-saving. Power consumption: ≤3W, Temperature control range: -50℃~99℃, Accuracy: ±1℃, Power supply: 110-220Vac 50Hz/60Hz, Output: 2 relays, Cool/Heat (10A/250Vac).</p> <p>【Multifunctional】This incubator thermostat supports temperature calibration, compressor delay protection, alarm when the temperature exceeds the temperature limit or sensor error, all parameter settings can be saved after restarting.</p> <p>【2m Waterproof Probe】This digital temperature controller can be used in humid and aquatic environment. Such as aquarium, seafood machine, aquaculture, hatchery, terrarium, vivarium, seedling heat mat, incubator, brewing, freezer, water tanks, refrigerator, industrial chiller, fermentation, industrial equipment, etc.</p> <p>Specification:</p> <p></p> <p>Temperature control range: -50 ~ +99 °C</p> <p>Difference set value: 0.3 ~ 10 °C</p> <p>Accuracy: ±1 °C</p> <p>Measuring input: 2m waterproof probe</p> <p>Power supply: 220VAC 50 / 60Hz</p> <p>Output relay: Two Cool 10A / 250VAC relays; Heat 10A /250VAC</p> <p>Size: 75mm * 34mm * 85mm</p> <p>Power consumption: ≤3W</p> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
