1. Overview 

What is ITC-308? 

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-n-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  1200W(110V)  /  2200W(220V), 

it’s suitable for most applications. 

 

ITC-308  is  designed  with  compressor  delay  protection  for  refrigeration,  high  and  low 
temperature alarm, and sensor fault alarm, which makes the temperature controller more 

safe and reliable. Functions such as temperature calibration, separately set differential for 

refrigeration and heating, enable more accurate temperature control. 
 

Main features 

 

 

Plug and play design, easy to use;  

 

Dual relay output, be able to connect with refrigeration and heating equipment at the 

same time;
