【Connect heater & cooler at the same time】No more frequently change wiring between heater and cooler. This temperature regulator has 2 relays. Compared with other 1 relay temperature controllers, you can wire 2 appliances (heater and cooler) at the same time. (Please kindly note no outlets, wiring needed).<br>【High accuracy】Made of ABS heavy-duty and anti-flamming plastic shell with embedded structure, this digital dual relay thermostat is safe and energy saving. Accuracy: ±1°F, Temperature control range: -58~212°F, Power consumption: ≤3W, Power Supply: 110VAC 50Hz/60Hz. Output: 2 Relays, Cooling (10A/110-220VAC) / Heating (10A/110-220VAC).<br>【Multi-functional】This incubator thermostat ac110V supports temperature calibration, compressor delay protection, alarm when temperature exceeds temperature limit or when sensor error, all parameters setting can be saved after restart. There is no voltage output directly, you need to connect additional power supply for the load.<br>【2m Waterproof probe】Digital temperature controller 110V can be used in moisture and water environment, you can use it in home brewing, fridge, pet breeding, reptile, tank, incubation, fermentation, seedling heat mat, accelerating germination, ect.<br>【Keep temperaure in desired range】It's on/off control mode. You can program by simply setting temperature set value and difference value, heating and cooling mode can be automatically switched. Fully utilize the stc microcontroller and NTC probe to have this temperature regulator has great accuracy.
