HKG-IV Type Control Cabinet Function Introduction I.Full-automatic type: (all the following functions are automatic) Water temperature display: both water temperature display of large tank and that of collector and pipeline range between 0 and 99 and the display accuracy is 1 . Water level display: water level display of large tank ranges between grade 0 and grade 4. Water tank display: running conditions of two water tanks are displayed on separate screens. Collector display: running conditions of two groups of collector are displayed on separate screens. Temperature-controlled water inlet: in case tank temperature is 5 higher than the set temperature and water level is lower than grade 4, solenoid valve will be started. Timed water inlet: under timed water inlet state, if the set time is reached, solenoid valve will be started. Constant-level water inlet: in case tank water level is lower than water inlet level, solenoid valve will be started. Dry burning-resistant function: in case electric heating conditions are met but water level is Lower than grade 1, solenoid valve will be started. Timed electric heating: under timed electric heating state, if the set time is reached, solenoid valve will be started. Intelligent electric heating: Intelligent turns on after the key is pressed and then intelligent electric heating function will be started. Anti-freezing electric heating: in case tank temperature is lower than the set temperature and water level is higher than grade 1, electric heating will be started. Circulation of temperature difference: inspect difference in temperatures of collector and water tank. In case the temperature difference is greater than the set value, circulation pump will be started. Anti-pipe-explosion circulation: in case collector temperature is higher than 95 , circulation Pump will run in accordance with the set time period. Timed circulation at constant temperature: within the set time, if pipeline temperature is 5 lower than the set temperature, circulation pump will be started; if the set temperature is reached, circulation pump will be shut down. Timed pipeline circulation: under timed water use state, if tank water level is higher than grade 1, the circulation will be enabled and circulation pump will be shut down after 10 minutes. Anti-freezing circulation: inspect the pipeline temperature and conduct circulation to prevent pipeline being frost-damaged. Separate anti-freezing control function: in case the temperature of anti-freezing sensor is lower than the starting temperature, anti-freezing circulation pump (ribbon heater) will be started to prevent header being frost-damaged. Timed water use: under timed water use state, if the set time is reached, water pump will be Started. Earth leakage protection: leakage circuit breaker is set in power supply line. In case the phase line has the operable leakage current to ground, power supply will be cut off automatically. Power-off anti-pipe-explosion function: in case of energizing after power off, to prevent pipe explosion of collector, when collector temperature is greater than or equal to 90 and temperature difference between collector and water tank is greater than or equal to 30 , all circulation functions of heat collecting temperature difference will be disabled.
