SOLAR CONTROLLER FOR COLLECTORS ST-402N PWM TECH

Controller for solar collectors

Functions performed by the controller:

• control of pumps (or pump and valve)
• control of pump operation with PWM signal
• Supervision and operation of the solar system for nine system configurations
• protection against overheating and freezing of the collector
• possibility of connecting an additional device: circulation pump, electric heater or giving a signal to the central heating boiler in order to ignite it

Controller equipment:

• large clear LCD display
• collector temperature sensor
• heat storage temperature sensor
• housing made of high quality materials
