Description
TWO TEMPERATURE ZONES: It is equipped with two output controls, temperature difference control, and two temperature zones. SCHOOL USE: The products are used in solar water heaters; the temperature difference and temperature control the output. SMART: When the temperature reaches the set value, the water pump circulation is automatically activated, and temperature balance between the two temperature zones is achieved. AUTOMATIC: It controls the heating system and automatically maintains the water temperature within the temperature difference range. The other channel controls the electric heating; when the solar heating does not reach the set temperature, the electric heating system can automatically start and heat to the set temperature. Specification: Operating Voltage: AC220V±10% (50Hz/60Hz) Output Load: 5A/220V/AC Power Consumption: ≤3W Heating Control Range: 2°C~99°C Temperature Difference Start Control: 3°C~50°C Resolution: 1°C Accuracy: ±1°C Input Signal: 2-channel sensor, 20KX2MX2
