Operational faults

8 Operational faults

Malfunctions or faults are indicated by the

icon blinking on the display.

8.1Sensor failure

The following list explains how the controller responds to the failure of the different sensors. Safety functions such as frost protection and excess temperature protection no longer work when a sensor fails.

￿Outdoor sensor AF: When the outdoor sensor fails, the controller uses a flow temperature set point of 50 °C or the Max. flow temperature (when the Max. flow temperature is smaller than 50 °C).

￿Flow sensor in heating circuit VF1/VF2: When the flow sensor is defective, the controller continues to work with the associated valve in the 30 % valve position. DHW heating which uses such a sensor to measure the charging temperature is interrupted. In systems Anl 4, 5, 6 and 11, the failure of flow sensor VF2 cause the DHW control valve to close.

￿Flow sensor in DHW circuit VF3: When the flow sensor VF3 is defective, the DHW heating takes place without change in lag/lead sequence.

￿Return flow sensor RüF1/RüF2: The controller continues to function without the return tem- perature limitation when the return flow sensor fails.

￿Room sensor RF: The controller functions using the settings for operation without room sen- sor when the room sensor fails. For example, optimization mode switches to the reduced op- eration mode. Adaptation mode is interrupted. The last defined heating characteristic is not changed anymore.

￿Storage tank sensor SF1/SF 2: When one of the sensors fail, DHW heating no longer takes place.

￿Solar circuit sensor SF2/CF: When one of the sensors fails, the solar circuit pump is switched off.

8.2Collective error alarm

As an alternative to the Pump management function, a fault alarm can be indicated over the bi- nary output BA8. Should the error status register FSr indicate a fault, the binary output BA8 is activated.

5476 specifications

The Samson 5476 is a high-performance microphone designed for professional audio applications, offering exceptional quality and versatility for various recording environments. Known for its robust build and advanced features, the 5476 is a reliable choice for musicians, broadcasters, and sound engineers.

One of the standout characteristics of the Samson 5476 is its cardioid polar pattern, which effectively isolates the sound source while minimizing background noise. This feature is especially beneficial in live performance settings or during studio recordings where external noise can be a challenge. The microphone’s frequency response ranges from 20 Hz to 20 kHz, making it suitable for capturing a wide variety of sound sources, from deep bass notes to crisp high frequencies.

The 5476 incorporates a dynamic transducer that enhances its durability and reliability, ensuring it can withstand the rigors of frequent use. The built-in shock mount system further reduces handling noise and vibrations, allowing for clearer audio capture. Additionally, the microphone is equipped with a built-in pop filter, which mitigates plosive sounds that can occur during vocal recordings.

This microphone also features a low impedance output, ensuring compatibility with a wide range of mixing consoles and recording interfaces. Users can easily connect the 5476 to XLR inputs, making it straightforward to integrate into any professional audio setup. The microphone’s high output level ensures excellent signal integrity, providing clean and precise audio reproduction.

Another notable technology in the Samson 5476 is its advanced capsule design, which helps to enhance the microphone's sensitivity and transient response. This results in natural-sounding audio, whether it’s used for vocals, instruments, or ambient sounds. The microphone’s construction also includes a durable metal body that can withstand the wear and tear of live performances and frequent handling.

In summary, the Samson 5476 is a versatile and reliable microphone that combines advanced technology with practical features suited for both studio and live environments.
