2. The thermal energy is measured in kcal (kWh or MWh) 1 kcal = is the energy necessary to raise up 1 °C temperature of 1 kg of water If we want to bring 50 liters (50 kg) of water from 10 °C temperature to 40 °C, we have cp x G x Δt = 1 x 50 x 30 = 1500 kcal = 1,74 kWh It is equal to use one hour radiator of 1500 kcal/h, which is aproximately 0,15 € (for traditional GPL boiler)

4. The heat Q used it is “counted” by the “heat gauge” The concept Fluid: water Use: Hot and Cold Plant Inlet Outlet

5. How to deliver the kit The Energy Box module is supplied without flow meters and without liters gauges to avoid any theft in the jobsite. The box is in zinc metal with key lock. + It is necessary to complete it with the DIRECT reading devices or with M-BUS net readers.

6. Components and operation The motorized 4 ways valves it is operated by a room thermostat. When the thermostat give the signal to open the valve, the water enter in the lodging and the calories meters quantify the energie consumption. The differential by-pass realize the pressure drops as a 4 ways valve completely opened. This in order to stabilize the flow conditions of the centralized plant. The Y filter it is fundamental for the circuit starting for the cleaning of the plant. Might be substituted by a balancing valve (optionl)Successively must be installed the energie meters and calories counters

23. Cabinet for heating/cooling and hot/cold sanitary water measuring consumption with several users. The cabinets are available up to maximum 4 lodgings or maximum 6 lodgings. The cabinets can be installed built-in or off-track and wall mounted.

25. The reading consumption of heating (hot/cold water) and sanitary water (hot/cold water) can be done in two ways: Directly from the display (DIRECT READ) Sending the data to a central station (M-Bus NET)

27. The MID Directive 2004/22/CE Directive from the European Parliament and 31 March 2004 council related to the measuring instruments. In March of 2004 the European Parliament issued the directive 2004/22/CE (MID). the device water gauges heat gauges The directive is applied to the device and to system with measuring functions which are defined in the specific attachments, related to water gauges, gas gauges and volume conversion, active electric energy counters and measure transformers, heat gauges, continuous and dynamic flow measuring systems different from water, automatic weight measuring systems, taximeters, dimension measuring systems, exhaust gas measuring gauges. The scope of the directive is to protect the final consumer which commercial transactions are connected to this instruments. 2004/22/CE Directive of the European Parliament and 31 March 2004 Council related to the measuring instruments. The directive foresee that the manufacturer accredit the counter gauge with a new mark: CE-M (totally different from CE mark). The CE-M mark certify the quality, the precision, the conformity of the counter gauge and the minimum parameters that grant the constancy of the precision, etc… protecting the consumers and the commercial deals.

28. A-MAGNETIC: does not get dirty and keep the precision during the time (minimum duration 10 years). LITHIUM BATTERIES: non removable LCD DISPLAY with 8 digits and special characters Direct reading energy device

39. It is necessary for the connection of maximum 2 counter liters to the M-Bus net Use 2 wires cables Maximum length: 10 meters Transform a signal arriving from a counter liters (1 impulse = 10 liters) in a M-Bus signal To be configured with MBCONF Software and Micro-Master device Pad A Battery: lasting 18 days/year for 10 years The battery must be activated !!! The adaptor must be activated opening the upper part of the terminal cover and positioning the jumper on both pins It works in case there is a current shot down! Impulse Adaptor

Use a SIM Card enabled for DATA traffic (not included)

49. M-Bus net lenght The signal must not be distorted. An important matter is the lenght of the net (The sum of all the cables lenghts). Lower the reading speed of the data (Baud rate), the longer could be the wiring net. Baudrate96002400300 Max net lenght1 km4 km12 km

51. - Connect the PC to the Micro-Master - Connect the Micro-Master to the device (Impulses Adaptor or Calories Counter), using the “M-Bus net” contacts still free. - Using the MBCONF software, assign a 3 digits code to each periferical items (Liters Counter or Calories Counter). This code is the PRIMARY ADDRESS - The software automatically recognize for each devices the correspondent “serial number” (it is an 8 digit number). This code is the SECONDARY ADDRESS System Configuration

54. - Connect the PC to the M-Bus net, without using the Micro-Master - Using the software FSERVICE find out each devices - Export the data in an excel file NOTE: the periferical devices transmit the data with a certain speed called BAUD (“changings”/sec). For the searching it is important set up a speed field (baudrate) between 300 and 2400 baud, to have the security to find all the connected devices. Data Read
