DescriptionConnect heater and cooler at the same timeNo need to change the wiring between heater and cooler frequently. This temperature controller with sensor has 2 relays. Compared to other 1-relay temperature controllers, you can wire 2 devices (heating and cooling) at the same time. Please note there are no outlets, wiring required.Keep the temperature within the desired rangeThis is 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 stc microcontroller and NTC probe to make this temperature controller have high accuracy.High AccuracyMade of sturdy and flame-proof ABS plastic shell with integrated structure, this thermostat dual relay digital is safe and energy efficient. Power consumption: 3W, temperature control range: -50~99, accuracy: 1, power supply: 110-220Vac 50Hz/60Hz, output: 2 relays, Cool/Heat (10A/250Vac) .MultifunctionalThis incubator thermostat supports temperature calibration, compressor delay protection, alarm when the temperature exceeds the temperature limit or when there is a sensor error, all parameter settings can be saved after reboot.2m waterproof probeThis digital temperature controller can be used in wet and aquatic environment. Such as aquarium, seafood machine, aquaculture, hatchery, terrarium, vivarium, seedling heating mat, incubator, brewer, freezer, water tanks, refrigerator, the industrial chiller, fermentation, industrial equipment, etc.Specification:Temperature control range: -50~+ 99CDifference set value: 0.3 ~ 10CAccuracy: 1CMeasurement input: Waterproof probe 2mPower supply: 220VAC 50/60HzOutput relays: Two Cool 10A/250VAC relays; Heat 10A /250VACSize: 75mm*34mm*85mmPower Consumption: 3W
