This device is widely used in incubators, refrigerators, and laboratories to provide an ideal and stable environment. Setup and Programming Guide The device has two separate screens; the left side (OUT1) is for controlling temperature in degrees Celsius (°C), and the right side (OUT2) is for controlling relative humidity (%RH). 1. Setting Temperature (OUT1) Set Operating Temperature (Start Temperature): Press the up arrow button (for temperature) once to display the current start temperature. Press and hold the same button for 3 seconds until the numbers start flashing. Use the up and down arrow buttons to set the desired temperature for the heater or cooler to turn on. Set Stop Temperature: Press the down arrow button once to display the current stop temperature. Press and hold the same button for 3 seconds until the screen flashes.
