1) According to the deviation between the measured temperature of the air duct and the set temperature, adjust the opening of the waterway electric control valve according to the PID, so that the measured temperature reaches the set temperature.
Summer: If the air duct temperature is less than the set temperature, close the opening of the cold water valve to reduce the amount of chilled water.
If the air duct temperature is greater than the set temperature, increase the opening of the cold water valve and increase the amount of chilled water.
Winter: If the air duct temperature is greater than the set temperature, close the opening of the hot water valve to reduce the amount of hot water.
If the air duct temperature is less than the set temperature, increase the opening of the hot water valve to increase the amount of hot water.
2) Interlocking: When starting up, open the fresh air valve first and then the fan; when shutting down, turn off the fan first and then close the air valve. After the fan stops, the electric regulating water valve is automatically closed, and an alarm message is issued when the antifreeze switch is activated, and the coil water valve is automatically opened.
3) When the pressure difference between the two ends of the air filter is too large, an alarm will be given to prompt cleaning.
4) It has both on-site and remote control functions.
