Product description
Function
High-precision digital display, intelligent temperature controller, mainly used in the circulation of hot water, water return control system and other cases. Digital tube in real time high and low temperature zone temperature measurement Point temperature value. Through the high and low temperature difference between temperature and temperature setpoint, and the lower limit of the temperature difference to control the relay output, the implementation of the cold, thermal cycle, improve thermal efficiency. The operation and the control power supply are used to isolate the power supply, and the voltage fluctuations of the control board do not allow starting and stopping large power equipment.
Description of work
Two operating modes of the integration of this product: one mode of operation mode and two modes of operation mode.
One way of operating mode: when the DS-A temperature minus the DS-B temperature is greater than the set temperature difference, the relay is action, you can start the relay associated with the equipment. When the difference in temperature is less than the specified difference in temperature, relay A is disabled and the associated equipment stops working. DS-B is larger than DS-A, the relay does not move.
Two-way operation: when the absolute value of the difference between the two temperature sensors is greater than the specified temperature difference, the action relay, you can start the relay equipment. When the difference in temperature is less than the specified difference in temperature, relay A is disabled and the associated equipment stops working.
Example 1: Solar hot water circulation, high temperature sensor — low temperature sensor> 5.0 degrees, action relays, the difference back to 4.5 degrees is off. The low temperature sensor is larger than the high temperature sensor and the relay does not move.
Set the temperature difference to 5.0C, the reverse difference is set to 0.5 degrees, the operating mode is set to PP 1.
Example 1: air convection cycle, difference between two probes> 3.0 degrees, relay action, difference back to 2.7 degrees relay off. Low temperature
Set the temperature difference to 3.0C, the reverse difference is set to 0.3 degrees, the operating mode is set to PP 2.
Technical specifications
1. Based on a comparison of the temperature difference between the two points for measuring the temperature of high and low temperature, the operation of the water pump:
1) temperature difference = high temperature value low temperature value.
2 Operation mode: high temperature-low temperature> set the temperature, open the output, high temperature-low temperature <set the temperature-temperature return temperature, stop the output.
2 downloads automatically detect the number of sensors, there is no plug sensor, or simply plug in the probe, the alarm indicator is 0000.
3 permanent memory: after turning off the power again on the last set of parameters and starting the state.

Temperature Controller Parameter Table
Note: Initially there were two relay designs, the lower right corner of the four white terminals is all welding, but also leads to the fact that many customers accept the wrong ones, so Avoid customers choosing the wrong line. Please most buyers restored for purchase. New photos do not come and do not upload.
Connection description: Power supply side: blue P 2 P terminal + is positive, is negative, you can directly use the DC power line. Connect the power line through the handset, the flat right end can be used for dialing.
Output terminal: using a relay output, the output interface is a graph label: The middle is a common end, the graph connection is usually closed, the other end is often open.
Boot process
Connects to the power source and equipment, you can power (5-24 V)
Bootstrap detection sensor
Probe less than 2, the screen shows 0000 and with LED1, LED2, LED3 flash.
Two probes are inserted, the controller automatically reads the saved parameters.
Then show the set temperature difference, the LED yellow LED flashes 3 times (mode).
Then automatically enter the operation mode.
Two-sided temperature displays signs and indicators for use.
Relay action with sound and light alarm.
Parameter setting method
Press the set key, the yellow light flashes, the display sets the temperature difference, according to T-T + +, to set the required temperature difference. Display templates, such as 7.1C
Press the SET button again. Yellow Start flashing, display settings to set the temperature difference, in accordance with T-T + +, to set the temperature difference. Display templates such as H 1,2
Press the SET button again. Green Start blinking; the display settings are working in the mode according to T - T + + to set the model. Display patterns such as PP 2. PP 1 on behalf of one-way operation, PP 2 representative two-way operation.
Press the SET button to exit the setting again, the LED is fully showing the actual temperature of the measurement, this time the system automatically saves the settings, started to enter the work.
Special note: In the dial, T + +, T-key settings 4S without any key actions, the system automatically saves the current parameter settings, and then show the measurement temperature and enter the operation mode. Click the button, the button is automatically enlarged.
