Wide model range

Traditional wall mounted boilers - 31 models

In this article, using the example of gas wall-mounted boilers Baxi model rows Luna 3 Comfort, Main5 and Luna Duo-Tec MP (fig. 1) shows how remote control boiler through the system home automation("Smart home") Z-wave standard.

Rice. 1. Boilers Baxi model series Luna 3 Comfort, Main5 and Luna Duo-Tec MP

Usually, gas boilers used to provide country house warm, tuned in permanent job in the optimal mode, in which the least amount of fuel is consumed to obtain a unit of thermal energy per unit of time. But continuous work even in this optimal mode, it will lead to a significant overspending of gas, because there is no constant need for this amount of heat. Why constantly supply heat to the radiators, especially if there is no one in the house? Without harm to the house (the risks of "defrosting" of the heating circuit are leveled by the automation of the boiler itself), you can turn off the heating of the heating circuit during the absence of people in the house. As a rule, with good thermal insulation of the house, the decrease in the air temperature in the room within 6 hours will be no more than 2 ° C. And the heating radiators are capable of increasing the air temperature in the room by 2-2.5 ° C per hour.

Remote control gas boiler provides, in addition to ease of management and comfort, a significant benefit - there is no need to burn gas when you do not need to constantly maintain high fever heating batteries (for example, in the morning you left for work, there is no one in the house). You can transfer the boiler to the heating circuit heating mode in order to quickly increase the temperature in the house (for example, before leaving work, before arriving at the house) at any time if there is an Internet connection in the house - you can set up access from mobile phone... It is also possible to set an automatic scenario of switching on / off the boiler by the automatic control system smart home"Linked to the calendar.

Boiler controller boards of the Luna 3 Comfort, Main5 and Luna Duo-Tec MP models have connectors that allow “heat request” from the home automation system, bypassing the boiler's automation.

Here we will show an example of connecting wall-mounted gas boilers of different models from Baxi to a home automation system. Let's consider the implementation of the following functions:

• remote control of the gas boiler operation by “heat demand” (via the “heat demand” terminals) to ensure gas consumption savings;
• remote control of coolant temperatures in the heating circuit;
• monitoring the integrity of the boiler circuit;
• remote reading of gas meter readings;
• timely notification of leaks (in the boiler room, where the a large number of pipes, connections and equipment) and the emergency state of the boiler.

The tasks can be accomplished by installing the DCM-5.1.1-Z data acquisition module (equipped with a Z-wave standard automation system chip), to which, in turn, the following equipment must be connected:

• outdoor temperature T sensor (Pt1000 type - installed outside the house);
• two clamp-on temperature sensors T1 and T2 (type Pt1000 - installed on the flow and return pipes heating circuit);
• pressure sensor P (type OWEN PD100 or similar - the sensor is installed in a tee with a socket for the sensor, embedded in the boiler circuit);
• pulse output a gas meter (a low-frequency pulse sensor (reed switch) of the IN-Z61 type is connected to a gas meter, for example BG-10, or it is possible to use a meter already equipped with a pulse output);
• boiler control contacts (connection terminals are shown in fig. 3, 5 and 6).

The data collection module is designed for simultaneous work with 5 different sensors, transmission of measurement results via a wireless Z-Wave network and is able to control one external device (has one switching relay). The use of the data acquisition module simplifies the process of equipment installation, and also reduces the number of wires to be laid for connecting sensors. Instructions for configuring the data collection module are posted on the manufacturer's website:.

The use of the data collection module makes it possible to include in the “smart home control system” remote control of a gas boiler, remote control of parameters in the heating circuit and monitoring of gas consumption.

The home automation network of the Z-wave standard is controlled by a controller, which can be a Raspberry Pi single-board computer (with an installed RaZberry expansion board) or Fibaro Home Center 2. The boiler automation block diagram is shown in Fig. 2.

Figure 2. Block diagram of boiler automation

The data collection module is connected to five input channels: two patch temperature sensors T1 and T2, an outside air temperature sensor T, a pressure sensor P and a pulse output of the meter. The process of configuring the channels of the data acquisition module and the types of supported sensors are given in the instructions for the module:. Temperature sensors require installation on metal pipe, or to metal parts: fittings, sensors, etc. In this example, one T1 temperature sensor is installed on the supply line, the second T2 sensor is installed on the "return" line.

To monitor the integrity of the heating circuit, a pressure sensor is installed in the system, connected to the data acquisition module.

In addition to remote monitoring, temperature and pressure sensors can be useful in identifying some possible malfunctions: leaks, malfunctions of boiler equipment, etc. (for example, failure expansion tank can lead to a sharp change in pressure in the system, and vice versa, a gradual decrease in pressure indicates a leak from the boiler circuit). Also, a sharp increase in temperature after turning on the boiler may indicate a malfunction of the heat exchanger or circulation pump (which in turn indicates a pre-emergency state of the boiler).

The data collection module and the sensors connected to it via wired interfaces are installed in the boiler room. The data acquisition module communicates with the Z-wave network controller via a radio channel. The boiler control contacts (see Fig. 3, 5 and 6) are connected to the DA1 switching relay of the data acquisition module. In the cases considered ( model lines Main5, Luna 3 Comfort and Luna Duo-Tec MP), the connection is made to the connection terminals of the external (room) thermostat; in this case, it is necessary to remove the jumper (installed by the manufacturer). In fig. 4.1 and 5.1 show cutouts of connection diagrams from the technical documentation of the boiler manufacturer. In fig. 4 and 6 are shown appearance controllers of Baxi Luna 3 Comfort 240 FI and Main5 24 F boilers, respectively.

Note: in the boiler seriesLuna 3 Comfortthe manufacturer does not need to install the jumper; the relay of the data acquisition module should be connected to the terminals shown in Fig. 4.

Figure 6. General view of the boiler controller Baxi Main5 24 F

Activation of the relay of the data acquisition module provides the so-called “heat demand”, i.e. transferring the boiler to the heating circuit heating mode and heating the coolant to the set temperature. Accordingly, opening the relay leads to the transfer of the boiler to the DHW heating mode.

The Fibaro wireless leakage sensor is connected via radio directly to the controller. The wireless leakage sensor is powered by a built-in battery, is able to inform about the state of charge, and has a built-in warning light / sound alarm.

The data collection module and the sensors connected to it are installed in the boiler room (except for the external temperature sensor T). The data acquisition module communicates with the Z-wave network controller and the Fibaro leakage sensor via a radio channel.

RaZberry

Instructions for setting up and operating the controller are posted at the link:.

When using RaZberry as a Z-Wave network controller, it may be necessary to pre-configure the equipment, which should be carried out in the following order:

1. Add (if necessary, if not in your controller) a file describing the NEVOTON DCM-5.1.1-Z device. To do this, the NEVOTON DCM-5.1.1-Z.xml file must be downloaded from the manufacturer's website using the link and added to the folder:

/ opt / z-way-server / ZDDX on your RaZberry Pi.

After that, run the command:

1. Configure the data acquisition module to work with the installed sensors according to the table:

1. To convert sensor readings (if necessary) into the desired physical. value according to the formula: "Sensor value * Multiplier + Threshold", install and configure the module for converting physical quantities (DataSensorMultiplication - English name). You can download the converter from the manufacturer's website at the link:

Now you can configure a “virtual room” with installed and connected sensors in the “Smart Home” Z-wave interface.

Figure 7. Z-wave "Smart Home" interface

In fig. 7 shows an example of displaying sensor readings in the "Smart Home" environment. After installing and configuring the "Physical quantities conversion module", the readings of the pressure sensor and gas meter are converted to the usual units of measurement.

Also, the Z-way-server allows you to install the Climate Control module from the Online Apps (see Fig. 8), which is, in fact, a “virtual thermostat”. Like a regular thermostat, the Climate Control module will maintain the set temperature by turning the boiler on to heating the heating circuit. An example of setting up the "Climate Control" module is shown in Fig. nine.
