Temperature control The electric flow control valve is used to control the flow rate of the primary network so that the outlet of the secondary network maintains the set temperature. The flow rate of the primary network is controlled by a self-standing temperature regulating valve, so that the outlet of the secondary network maintains the set temperature. The outlet temperature of the secondary network is automatically adjusted according to the outdoor temperature. 2. Pressure and differential pressure control Secondary side supply and return water pressure difference control, secondary side return water pressure control 3. Automatic hydration Frequency conversion water supply, the pressure signal of the secondary network backwater is used to control the output of the frequency converter to achieve automatic water supply, so that the system maintains constant pressure. With the electrical control of the electric contact pressure gauge, the secondary network system is used to control the start and stop of the make-up pump compared with the upper and lower limits of previous years, so that the system maintains a constant pressure. 4. Local optimization Backwater temperature limit, heat flow (water flow) limit, backwater temperature difference limit, scale detection 5. Display alarm The parameters of temperature, pressure, heat, flow and outdoor temperature of the inlet and outlet of the primary and secondary networks are automatically monitored and controlled by the microcomputer, and the system overpressure, motor overheating, power phase loss, decontamination device clogging, etc. are automatically performed. Call the police. 6. Communication function The controller of the unit has a standard 485 communication interface, which can collect the parameters of the power station controller through the next round and the monitoring center in the active and passive mode, and upload the controller when the alarm occurs. 7. The function of the control zone of the unit is determined according to the actual situation of the heat exchange station, and it can be unattended.
