User Manual V1.0 2015-10-1
1. Overview 3. Keys instruction
●ITC-308 is an easy-to-use, safe and reliable dual relay output temperature
controller. 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.
●This product has Plug and Play design with dual relay, be able to connect with
refrigeration and heating equipment easily to realize ideal temperature control.
It’s equipped with dual LED display, and offers display options of Centigrade and
Fahrenheit, enabling more humanized temperature control. With large output
power 1,000W(110V) /2,000W(220V), it’s suitable for most applications.
● ITC-308 is designed with compressor delay protection for refrigeration, high and ① PV: Process Value. under running mode, display current temperature; under

●Heating/Cooling differential function could be set separately for refrigeration
and heating to protect temperature controller from violent change. 4.1 When the controller is working normally, short press “ ” key for one time,
then the heating differential (HD) will be displayed; short press “ ” for one time,
2. Specification then the cooling differential (CD) will be displayed. The screen will return to
normal display mode after 2 seconds.
