Solar collector controller


Principle of operation

EU-401N type thermoregulator is intended for operation of solar collector systems. This device controls the main (collector) pump on the basis of temperature measurement on the collector and in the accumulation tank. It may be connected to additional devices such as a mixing pump or an electric heater. It also enables to send a signal to the CH boiler to fire it up. Control of the circulation pump and sending the firing-up signal to the CH boiler is possible directly from the controller whereas in the case of the heater control an additional signal relay is necessary.

Functions performed by the controller:

  • - Control of the operation of pumps
  • - Supervision and handling the solar system operation
  • - Protection against overheating and freezing of the collector

Equipment of controller:

 

  • - Large and clear LCD display
  • - Collector temperature sensor
  • - Heat accumulator temperature sensor
  • - Casing made of high-quality materials resistant to high and low temperatures
  • Specifications Unit
    Supply voltage V 230V/50Hz +/- 10%
    Maximum power consumption W 4
    Accuracy of measurement °C 1
    Range of temperature settings °C 8÷90
    Thermal resistance of the tank sensor °C -25 : 100
    Thermal resistance of the collector sensor °C -24÷90/-30÷180 (krótkotrwała 200°C)
    Type of collector sensor   PT1000
    Output load of the collector pump A 1
    Output load of the additional device A 1
