Product information:
This product adopts STM8 high-speed professional temperature control chip, and adopts binary dial switch for temperature control and hysteresis.
It has the advantages of small size, convenient installation, accurate temperature control, adjustable backlash, etc., although it is not displayed compared with the professional thermostat.
Screen and temperature control buttons, but the control accuracy and professional no difference, and the price is only a fraction of a thousand, the cost is very high, this product can be used in (liquid, mold, space) and other control heating, can also be used (box, device control, cooling, etc., water, pet room, air conditioning, etc., of course, in the case of heat dissipation, for example, control the chassis, greenhouse, server heat dissipation, set the number of degrees above the start to stop below.

Product parameter setting:
According to your own needs, connect the circuit according to the drawing, the power supply is DC12V (+12V is positive GND is negative)
Placed by a temperature-controlled probe on an object that requires temperature control
For heating: please connect the 12V heater to -H+ (note the positive and negative poles)
For cooling: please connect the refrigerator to +C- (note the positive and negative poles)
For heat dissipation: please connect the refrigerator or cooling fan to +C- (note the positive and negative poles)
Indicator status description:
The red indicator light on the board illuminates to indicate that the cooling (+C-) has an output.
No light indicates that the heating (-H+) has an output
Parameter function description
The temperature control switchboard is set by dialing mode, 1-4 is the temperature control select 5-6 as the hysteresis setting, from right to left in binary mode from small to the large setting when the temperature control switch is fully closed, Only -H+ has output, not controlled
Example: Add a temperature control switch to the radiator, turn on the cooling fan when the temperature is higher than 40 degrees, and turn off the cooling fan when the temperature is lower than 35 degrees.
Connect the DC12V to the power supply terminal and connect the cooling fan to the +C-
The parameter we want to set is temperature control = 40 hystereses = 5
According to the parameter table, it is known that 24 is controlled to 40 degrees, 5 is 5 degrees, and the other is fully closed.
Package includes:
1 x High precision digital temperature control switch
