Specifications:

Dimensions: 78mm x 50mm
Temperature Range: -9℃ – 99℃
Accuracy: +/- 1℃
Input Power Supply: 9V – 12V DC
Output Relay: 220V 10A AC / 12V 10A DC

Operation:

Starting Indicator Light: (RED) indicates that the relay is currently closed and providing power to the load.
Cutoff Indicator: (GREEN) indicates that the relay is currently open and no power is flowing to the load.
Left Display: (GREEN NUMBERS) displays the set starting temperature.
Middle Display: (RED NUMBERS) displays the current detected temperature.
Right Display: (GREEN NUMBERS) displays the set cutoff temperature.
Arrow Buttons: Below the left and right displays are 2 +/- buttons, these are for setting the target temperature for both Starting and Cutoff.

Usage Examples:

Using the controller for cooling – for this kind of operation, the Starting temperature needs to be higher than the Cutoff temperature, for example.
You would like a fan to come on when a room reaches 30℃ or above and then turn off when the room cools down to 25℃ or below. Set the starting temperature to 30℃ and the cutoff temperature to 25℃.

Using the controller for heating – for this kind of operation, the Starting temperature needs to be lower than the Cutoff temperature, for example.
You would like a heater to come on when a room is 20℃ or below and turn off when the room is 25℃ or above. Set the starting temperature to 20℃ and the cutoff temperature to 25℃.
