Thermostat Dual Relay Heating and Cooling Temperature Controller for Carboy, Fermenter, Greenhouse, Terrarium, Home Brewing

Heating and Cooling Temperature Controller


ITC-308 is an easy-to-use, safe and reliable dual relay output temperature controller. D esigned with compressor delay protection for refrigeration, high and low temperature alarm, and sensor fault alarm, which makes the ITC-308 more safe and reliable. Functions such as temperature calibration, separately set differential for refrigeration and heating, enable more accurate temperature control.

With large output power 1,000W(110V) /2,000W(220V), it’s suitable for most applications.   It can be used as Over-temperature protection and automatic temperature control system for various electric appliances such as equipment for home-brew, aquarium, pet breeding, incubation, BBQ, seedling heat mats, oven temperature control, terrestrial heat control, constant temperature cycle of heating pump, culture fermentation, accelerating germination, electric radiator, electric oven, etc.
