function
High precision digital display intelligent temperature controller, mainly used in hot water circulation, return water system control and other occasions. Digital tube real time high and low temperature zone temperature measurement point temperature value. Through the high and low temperature difference between the temperature and the set temperature value, and the lower limit of the temperature difference to control the relay output, realize the cold, thermal cycle, improve the thermal efficiency. The work and the control power supply are used to isolate the power supply, and the voltage fluctuation of the control board is prevented from starting and stopping of the large power equipment.
Job description
Two working modes of this product integration: one way working mode and two way working mode.
One way working mode: when the DS-A temperature minus the DS-B temperature is greater than the set temperature difference, the relay A action, you can start the relay related equipment. When the temperature difference is less than the preset temperature difference return difference, the relay A is disconnected, and the related equipment stops working. DS-B is greater than DS-A, the relay does not move.
Two way working mode: when the absolute value of the difference between the two sensor temperature is greater than the preset temperature difference, relay A action, you can start the relay related equipment. When the temperature difference is less than the preset temperature difference return difference, the relay A is disconnected, and the related equipment stops working.
Set example 1: solar hot water circulation, high temperature probe - low temperature probe >5.0 degrees, relay action, the difference back to 4.5 degrees relay off. The low temperature probe is larger than the high temperature probe, and the relay does not move.
Set the temperature difference is 5.0C, the return difference is set to 0.5 degrees, the working mode is set to PP 1.
Set example 1: air convection cycle, the difference between the two probes >3.0 degrees, relay action, the difference back to 2.7 degrees relay off. low temperature
Set the temperature difference is 3.0C, the return difference is set to 0.3 degrees, the working mode is set to PP 2.
technical parameter
1. based on the comparison of the temperature difference between the two temperature measuring points of the high temperature and low temperature, the operation of the water pump:
1) temperature difference = high temperature value low temperature value.
2 operating mode: high temperature - low temperature > set temperature, open the output, high temperature - low temperature < set temperature - return temperature, stop the output.
2 boot automatically detect the number of sensors, no plug sensor or just plug in a sensing probe, the alarm display 0000 indicator light.
3 permanent memory: after the power is cut off again on the last set of parameters and running state into operation.
