DIGITAL CLIMATIC CONTROL UNIT

Geca has engineered a very simple thermoregulation control unit with the same concept of its chronothermostats, suitable for centralized heating systems, to control and program thermal flows. A big display and only four keys and the programming is already done. The evolution of control unit RE150 is the new control unit RE200 completely digital with climatic compensation function; modular regulation with characteristic of integrative proportional to control mixing valves or burner. The control unit simply regulate the inlet water temperature in relation to the external ambient temperature. The external temperatures are normally detected by special probes indicating the values detected to the control unit which modify the inlet water temperature proportionally to the external temperature. The control unit will be available in both wall mounting or DIN rail mounting box.
