1、 Overview
This series of temperature controllers is an intelligent digital temperature measurement and control product that integrates temperature measurement, display, output, and control. This product is a fully electronic structure, with a front end equipped with an isolation film filled oil pressure resistance temperature sensor. It is converted by high-precision A/D, processed by a microprocessor, displayed on site, and outputs one analog signal and four switching signals.
This intelligent digital temperature transmitter is flexible to use, easy to operate, easy to debug, and safe and reliable. Widely used in industries such as hydropower, tap water, petroleum, chemical, mechanical, hydraulic, etc., for on-site measurement, display, and control of fluid medium temperature

5.2 Electrical connections
The switching point is determined by the configuration of the pull-in value and release value. When the pull-in value is greater than the release value, it is the upper limit alarm output (normally open function), and when the pull-in value is less than the release value, it is the lower limit alarm output (normally closed function). The difference between the pull-in value and the release value is the return difference of the switching point.
Example: To set the switch point 1 as the upper limit alarm output (normally open function) at 4 ℃ for suction and below 3.9 ℃ for disconnection,; Switch point 2 is the lower limit alarm output (normally closed function) that is disconnected at 10 ℃ and absorbed below 9.9 ℃:
Enter menu: Settings
AL1H=4.00 AL1L=3.9
AL2H=9.9 AL1L=10.00
Press the "SET" button
● Display "LOCK" (prompt for password input)
Press the ▲ or ▼ keys to enter the password "1",
Press the "SET" button to confirm
Press the ▲ or ▼ keys to scroll up or down for menu selection (AL1H, AL1L, AL2H
AL2L, END)
Press the "SET" button to enter the selected menu. Switch when the suction value reaches and reply when the temperature drops below the release value
6.2 Setting Switch Points

AL1H is the pull-in value of switch 1, AL1L is the release value of switch 1
AL2H is the pull-in value of switch 2, AL2L is the release value of switch 2
AL3H is the pull-in value of switch 1, AL3L is the release value of switch 1
AL4H is the pull-in value of switch 2, AL4L is the release value of switch 2
END Save Exit
Press the ▲ or ▼ keys to change the settings

Press the "SET" key to confirm, and if necessary, use the ▲ or ▼ keys to select other menus for modification.
After completing the modifications, select the "END" menu and press the "SET" button to confirm saving and exit.
If there is no key pressed for 30 seconds, the setting state will automatically exit, but the modified data will not be saved
