EBV dual differential temperature controller CETA 103

Dual differential temperature controller for one or two heat sources and one or two hot-water storage tanks.
The controller can be used, for example, to combine a solid-fuel boiler with buffer tank and solar system, and it also allows you to control solar systems with different roof orientations or to charge two separate storage tanks; a circulation pump in the system can be speed-controlled via a PWM signal.
The CETA differential temperature controller provides four relay outputs, four sensor inputs and a clear LCD display, is suitable for wall or DIN-rail mounting, and can be extended via data bus to up to four controllers, with heat balancing possible using an optional return sensor.
