Start indicator, LED and buzzer status description:

Start indicator: START (red) light,meaning relay is closed,device start working

Stop lights: STOP (green) light,meaning relay is off,device stop working

Screen:Middle red number means the detected temperature;
Left green number means the set start temperature;
Right green number means the set stop temperature;

Key:

START "▲ ▼" set the start temperature

STOP "▲ ▼" set the stop temperature

Operating Instructions

1. High temperature start:
Set the starting temperature value> stop temperature value,
When the detected temperature ≥ start temperature, the relay is closed, refrigeration equipment begin to work;
When the detected temperature ≤ stop temperature, the relay off, refrigeration equipment stops working
For example: Set the starting temperature is 20 ℃, stop temperature is 15 ℃,
When the detected temperature ≥ 20 ℃, the relay is closed, the start Indicator (red) lights;
When the detected temperature value ≤ 15 ℃, the relay off, stop Indicator (green) light.

2. Cold start:
Start temperature set value< stop temperature value,
When the detected temperature ≤ start temperature relay is closed, the heating device operates;
When the detected temperature ≥ stop temperature, the relay off, the heating device is stopped.
For example: Set the starting temperature is 15 ℃, stop temperature is 20 ℃,
When the detected temperature value ≤ 15 ℃, the relay is closed, the start Indicator (red) lights;
When the detected temperature ≥ 20 ℃, the relay off, stop Indicator (green) light.

3. set to start when the temperature value = stop temperature value, the relay off.
