In the standby position, only one control lamp is visible on the Vitotronic 300 boiler controller. Only when the settings are to be changed is the control mechanism opened out like a drawer and swung free. The terminal box, which is easily accessible for installation and maintenance work, is located beneath the control panel. Only one fastening has to be released to swing the control unit upwards.
