1 071N July 01 Versions GY01, GY0 igure 1 GY01 GY0 Description The G user satellites are the ideal metering solution in condominium systems with the centralised production of heating water and zone-based distribution, where there is a need to produce sanitary hot water locally (in each individual apartment). With the aid of the satellites, a delivery pipe and a return pipe distribute energy for heating both rooms and sanitary water; in addition to this, there is just one pipe for the cold sanitary water. This avoids the need to install pipes for sanitary hot water distribution and the relative recirculation.

The insulated stainless steel plate exchanger produces sanitary hot water in combination with the motorised priority valve that is activated by the sanitary circuit flow switch. The thermostatic mixer allows you to adjust the temperature of the sanitary water sent to users, within a range of 8 0.

N: Within the satellite there is an adjustment lockshield valve for balancing the heating circuits. No device is envisaged for balancing HSW production circuits: if necessary, you can fit one on the distribution system side. If there is no sanitary water meter, the cold sanitary water inlet in the satellite can be set from below (inlet L in figure, with the connection G closed and no check valve). igure Operation diagram The inputs from the boiler room are from above, while the outputs to the home are from below. The first unit at the top left (G) relates to sanitary water; the water meter () measures the total flow rate. old sanitary water emerges from the second pipe at the bottom left (L); the first (H) feeds out hot sanitary water, mixed by means of a thermostatic mixer. The hot heating fluid from the centralised utility room enters from above, via the second pipe from the left (); after passing through a filter, its temperature and pressure (analogue manometer) are measured. Then there is the priority valve that, commanded by the hot sanitary water flow switch, deviates the heating fluid (heating side) towards the plate exchanger. When there is no hot sanitary water request, the heating fluid (heating side) passes through the priority valve and then meets the -way zone heating valve (that may also be -way if the bypass with adjustment lockshield valve is closed). The adjustment lockshield valve downstream from the zone heating valve regulates the flow rate in heating mode. On the return line towards the central unit there is a thermal energy meter () with built-in temperature probe.

On the heating delivery unit there is a filter, a pressure gauge, a balancing valve, a balancing lockshield valve and a -way zone valve motorizable. On the return unit there is a plastic spacer for inserting the heat energy meter. The GY0 satellite has a particular way of producing sanitary hot water. The insulated stainless steel plate exchanger works alongside a thermostatic valve with remote bulb. Thanks to the thermostatic control of the water temperature and primary flow rate, operation is entirely mechanical; the lack of electric devices reduces the need for maintenance.

Note. Within the satellite there is an adjustment lockshield valve for balancing the heating circuits. No device is envisaged for balancing SHW production circuits: if necessary, you can fit one on the distribution system side. If there is no sanitary water meter, the sanitary cold water inlet in the satellite can be set from below (inlet L in figure, with the connection G closed and no check valve). D Legend Legend 1a Heat exchanger heck valve (optional) Pressure gauge Differential pressure control valve igure Operating flow The operating flow is shown in figure. The inputs from the boiler room are from above, while the outputs to the home are from below. The first unit at the top left relates to sanitary water; the water meter () measures the total flow rate. sanitary cold water emerges from the second pipe at the bottom left; the first feeds out sanitary hot water, mixed by means of a thermostatic mixer. The hot heating fluid from the centralised utility room enters from above, via the second pipe from the left; after a filter, there is the housing for the energy meter temperature probe. This is followed by a differential pressure control valve between the delivery and the primary return. Together with the balancing valve, this valve implements the dynamic balancing characteristic described in figure. The balancing valve allows the static adjustment of the flow rate to the apartment. The differential bypass valve allows dynamic balancing in addition to static: if the flow rate to the apartment exceeds the threshold value of the differential pressure valve, the latter opens the bypass to automatically re-balance the flow rate.

11 0N July 01 Version GY0 07U98 Downstream from the balancing valve there are - in parallel - the circuits for heating and sanitary hot water production which can therefore operate simultaneously, guaranteeing greater comfort compared with systems that interrupt the heating function to give priority to sanitary water production. Heating: on the heating side there is a zone valve and an adjustment lockshield valve. The zone valve can be commanded by a K70 actuator (to be ordered separately) that is activated by a thermostat command. The adjustment lockshield valve regulates the primary flow rate part destined for heating, given that the flow rate needed for sanitary hot water production is usually greater than that for heating. Sanitary hot water production: a thermostatic valve with remote bulb on the exchanger outlet minimises the primary flow rate while sanitary hot water is being produced. Thermal energy metering: on the return to the central unit there is a connection point for housing an energy meter; the thermal energy meter () calculates energy consumption for heating and sanitary hot water production. The delivery probe of the energy meter must be installed in the housing on the delivery unit. The meter return temperature probe is integrated in the energy meter body.

In this way, the flow rate - and hence the primary power request - is reduced. It should be noted that when the zone valve is closed and there is no SHW production request, the energy meter still gives a count equal to the dissipation in the satellite.
