Functions of the DHW circuit

Once a parallel pump operation cycle has been activated and the time for Stop parallel opera- tion has elapsed, system deviations greater than 5 °C cause the controller to suspend parallel operation for 10 minutes and to apply priority operation.

Function	WE	Configuration
Parallel pump operation	OFF	FB9 = ON, PU
	10 min	Stop parallel operation / 2 to 10 min

Note!

In system Anl 9, the control valve of the underfloor heating circuit is always closed with the function block setting FB9 = OFF. With the setting FB9 = ON, select “PU“ to ensure it remains in control operation even the parallel operation has been interrupted due to system deviations.

In many district heating systems with primary DHW heating, the allotted amount of water is only intended to supply the heating system. As a result, the capacity required for DHW heating needs to be taken from the heating system when great heating loads occur; and this, until DHW heating has been concluded.

Nevertheless, heating operation is not simply to be interrupted. Only the amount of energy re- quired for DHW heating is to be deducted. This can be achieved by using the priority functions Reverse control and Set-back operation.

6.9.1 Reverse control

The capacity demand of the heating circuit is reduced when there is a system deviation of more than 5 °C in the DHW circuit. This is achieved by the three-step output of the DHW circuit work- ing in the opposite direction compared to the heating circuit control valve.

The amount of time in which the priority for the DHW circuit is given is set in the Priority in case of deviation parameter.

Priority for	OFF	FB8 = ON, select “In“
DHW circuit	10 min	Priority in case of deviation / 2 to 10 min

6.9.2 Set-back operation

The heating circuit is set back to reduced operation for 20 minutes when a system deviation of more than 5 °C arises in the DHW circuit. Its capacity demand is reduced by the value in

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. Its cardioid pattern, dynamic transducer, low impedance output, and robust build make it a valuable tool for any audio professional looking to achieve high-quality recordings. Whether for vocals, instruments, or broadcasting, the Samson 5476 delivers consistent performance and exceptional sound quality, making it a top choice in its class.
