Kromschroeder Lago FB Open Therm clock thermostat

Digital remote control unit with integrated room temperature sensor and an OpenTherm interface for the connection to a heat generator.
The remote control allows a variety of functions to be monitored from the living-room such as heating according to time schedule, setting the desired room and hot-water temperature and the control of the boiler values. Lago FB OT uses the weather or regulating function to give the boiler setpoint to the boiler controller so that the heat generator can deliver the optimum heat quantity as required. In conjunction with boiler controllers that support the OpenTherm SmartPower function, the display of the Lago FB OT remote control is illuminated during operation.
