Start and stop switches and seven segment display , led status description:
Start led indicator : START (red) indicator light, said the relay is ON, the device starts to work
Stop lights : STOP (green) light is on, the relay is OFF, the device stops working
Seven segment display: middle red LED display for the current temperature detected
- Left side seven segment to set the start temperature
- Right side seven segment to stop temperature
START "▲ ▼" to set the starting temperature
STOP "▲ ▼" set the stop temperature
1. High temperature start - cooling mode : set the start temperature value> stop temperature value, when the current temperature ≥ start temperature, the relay is ON(red led indicator ON), the device will work; when the current temperature ≤ stop temperature, the relay is OFF, the device will stop working (green led indicator ON).
2. Low temperature start - heating mode : set the start temperature <stop temperature value, when the current temperature ≤ start temperature, the relay is ON(red led indicator ON), the device will work; when the current temperature ≥ stop temperature, the relay is OFF, the device will stop working (green led indicator ON).
