ITEM NAME:2-CH 5-24V Digital LED Display Intelligent Temperature Controller with 2 probe F unction: 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 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.
