EU 400

Solar collector controller

EU-400 regulator is intended for controlling solar collector installation. It controls the main pump (collector pump) using temperature data measured on the collector and accumulation tank.

Optionally, it is possible to connect additional devices such as mixing pump or electric heater as well as to send a signal to initiate fire-up of the CH boiler. Controlling the mixing pump and sending CH boiler fire-up signal may be done directly from the controller whereas controlling the heater requires an additional signal relay.

Functions performed by the controller:

  • Pump operation control
  • Pump speed control
  • One configurable voltage output
  • Operating modes (vacation, defrosting)
  • Supervision and handling of the solar system operation
  • Protection against overheating and freezing of the collector
  • Anti-stop function
  • Anti-freeze function

Equipment of controller:

  • LED display
  • Collector temperature sensor
  • Accumulation tank temperature sensor
  • Casing made of high quality material resistant to high and low temperatures

EU 401 N

Solar collector controller

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
