4 Recording with wireless data transmission heat boxes are provided with heat consumption meters with wireless data transmission, without the need for a cable connection. A direct consumption reading is still possible via a digital display on the heat meter. Wireless transmission To save on meter reading time and respecting user privacy, consumption data can be communicated by a wireless signal sent from the heat consumption meters to the Network Nodes that receive and store data. Consumption data transmission made by heat meters is repeated 6 times a day. This automatic reading system allows the control of the building consumption from one single position quickly and with ease, avoiding possible reading errors. 4

5 The reading and transmission of consumption data can be done both locally and remotely using the optional accessories available. Direct transmission from network nodes Data transmitted by the network nodes can be directly downloaded from the remote reader device (optional) connected to a laptop. network node PC remote reader device Network nodes with gateway (RS232) remote transmission Data is read through a PC serial cable; the cable is connected to the main transmission network node positioned in the heating station. network node with gateway PC Network nodes with gateway (via GSM) remote transmission Data is read via the GSM telephone network through a PC connected to the main network node through a GSM modem.

10 Installation solutions Here are some examples of applications in centralised plant room installations serving buildings with more than one dwelling. Potterton Commercial high efficiency Sirius range condensing boilers are installed in the main plant room. DHW heating The measurement of heat production is assigned to the user who, with, can autonomously adjust the dwelling comfort level according to their own needs whether this is space heating or hot water. DHW heating Solution 1 Centralised DHW production In the first solution the DHW production is centralised: Sirius SAT (heating only models) manages the distribution of heat within the dwelling. DHW heating cylinder 10

11 Solution 2 DHW heating Local DHW production In the second solution, in addition to managing the space heating, also produces DHW with a plate heat exchanger for the dwelling. The diagram represents the distribution of the built-in heat-boxes on the floor, outside the dwelling to provide ease of access for direct meter reading or servicing.
