Weather-compensated heating circuit controller EU-i-1 with LCD display including wiring and flow sensor

The heating circuit controller EU-i-1 is the successor to DE.100

The convenient weather-compensated EU-i-1 heating control unit is used to control a servomotor in three- or four-way heating circuit mixers. The heating control unit can also be used as a return temperature booster in large boiler systems with a four-way mixer. This device regulates not only the flow temperature (output temperature) but also the return temperature, controlling the mixer motor so that the return temperature booster function is always active in the four-way mixer. The output temperature can also be controlled based on weather conditions using an outside sensor (included in delivery).

The second function of the heating control system is the weather-dependent, room-thermostat-controlled, or fixed-value-controlled control of a heating circuit mixer. Of course, the controller also controls a circulation pump and calibrates itself to the respective actuator.

The EU-i-1 heating controller features a very elegant design and a weekly programming with time-adjustable temperature reductions.
