Solar Collector Controller

* EU-401N controller in a new casing

Principle of Operation

The EU-401 temperature regulator is intended for the operation of the solar collector installation. This device controls the main (collector) pump on the basis of temperature measurement on the collector and in the accumulation tank. Optionally, it is possible to connect additional devices such as a mixing pump or an electric heater as well as feed the signal to the CH boiler in order to fire it up. It is possible to control the circulation pump as well as to feed the firing-up signal to the CH boiler directly from the controller, but an additional signal relay is necessary to control the heater.

Functions Performed by the Controller:

• Control of pump operation
• Supervision and handling the solar system’s operation
• Protection against collector overheating and freezing

Controller’s Equipment:

• Large clear display
• Collector temperature sensor
• Heat container temperature sensor
• A casing made from high-quality materials resistant to high and low temperatures
