EU402N - solar heating controller

EU-402 regulator is intended for controlling solar collector installation. It controls the main pump (collector pump) + other pump or valve 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:

- Control of the pumps (or a pump and a valve)

- Supervision and handling the solar system operation for 15 configurations of the system

- Protection against overheating and freezing of the collector

- The possibility of connecting EU-500 ETHERNET module

- The possibility of connecting EU-65 GSM module

- The possibility of connecting an additional device: (circulation pump or heater)

- Sending a signal to the Central Heating boiler to fire it up
Equipment of controller:

- Large, clear LCD display

- Collector temperature sensor

- Heat accumulator temperature sensor

- Casing made of high-quality materials resistant to high and low temperatures
