FOREWORD
The SIRIUS SAT user modules make it possible to independently manage heating requirements in centralised systems,
me- ter the heat distributed to each unit (flat or independently managed area) and transmit heat consumption data via
radio.
The following notes and instructions are addressed to fitters to allow them to carry out trouble-free installation. The operating instructions are contained in the “Start-up and operating instructions” section of this manual.
ATTENTION:
-
Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential
source of danger.
The appliance must be housed in the template casing supplied in a separate pack.
Flush the Domestic Hot Water circuit prior to use.

The models with pump separate the circuit from the head generated by the column pump by independently feeding the
internal heating circuit.
The models featuring domestic hot water production are fitted with a stainless steel instantaneous plate exchanger and
produce hot water at a temperature that can be adjusted using an electronic modulating device.
The dual-zone models can separately manage two heating zones at different temperatures and are ideal for combined
cen- tral heating systems (underfloor radiant panels at a low temperature with radiators at a high temperature).
2. INSTRUCTIONS PRIOR TO INSTALLATION
These appliances must be inserted in a centralised heating system, especially designed for this purpose, consistently with
their performance levels and power outputs.
The fitter must be legally qualified to install heating appliances.
Initial start-up must be performed by a POTTERTON COMMERCIAL - authorised Service Engineer, as indicated on the
attached sheet. Failure to observe the above will render the guarantee null and void.
Do the following before connecting the appliance:

3. CENTRALISED SYSTEM REQUIREMENTS
Some general indications concerning the installation of the centralised heating system are shown below. For
these types of plants, a cutting-edge bespoke design is always necessary in order to ensure ideal conditions of
comfort, save energy and reduce the environmental impact.
Install the boilers in a cascade arrangement (preferably condensation boilers with low pollutant emissions) of a suitable
size to optimise plant performance according to seasonal loads, user demand and Domestic Hot Water demand peaks.
The maximum installed power must consider a simultaneous use factor so as not to oversize the generator and consequently reduce operating efficiency.
The centralised plant must service the various floors of the building by means of columns positioned in the stairwells or
in utility rooms which should preferably be inspectable.
A hydraulic separator should always be fitted downline from the heat generator as this separates circulation in the generator from circulation in the columns.
The centralised plant must have the following features:
r "VUPNBUJDàMMJOH
r &YQBOTJPOTZTUFNTJ[FEBDDPSEJOHUPUPUBMQMBOUDBQBDJUZ
r 0WFSQSFTTVSFTBGFUZWBMWFTJ[FEBDDPSEJOHUPDVSSFOUMFHJTMBUJPO
Each suitably sized column must be fitted with a circulator (preferably at variable speed depending on the demand of the
modules), on/off valves and a dynamic balancing valve. Automatic air vents must be installed at the top of the columns.
The inlet sections must have the same pressure drop in order to allow the system to balance feed to all the user systems.
The recommended typology is three columns with a reverse return line.
Modules with Domestic Hot Water production require an appropriate centralised plant capacity so as to produce a thermal mass that can limit the instantaneous operation of the generator (column oversizing).
The columns and manifolds must be well lagged.
For models without pump (R/1 – RS), the heating circuit pressure drops downline from the user module (R = 0.3 KPa/m per
linear metre + local pressure drops) and the pressure drop of the module itself must also be considered when calculating
the pressure drops.
For models with pump (RP/1 – RSP – R2Z – RS2Z) make sure that the circuit pressure drops downline from the module (R
= 0,3 KPa/m per linear metre + local leaks) are compatible with the pump supplied together with the module. In this case,
the column pump must offset the circuit pressure drops upline from the module (a residue head is acceptable).
SIRIUS SAT user modules are fitted with an automatic by-pass valve which opens the circulation circuit when the pressure
drops exceed 60 kPa (inlet valve closed).

6. FLOW RATE/PRESSURE DROP CHARACTERISTICS (models without pump: R/1 – RS)
Models R/1
These models are fitted with a balancing valve (figure 5). This device is used to balance the flow of water circulating in the
single module in case of non-optimal distribution in the inlet pipes.
Figure 4 shows the Flow Rate – Pressure Drop curve with balancing valve in the wide open position.
Models RS
These models are fitted with two balancing devices.
The first device (balancing valve: Figure 5) is used to balance the flow of water circulating in the single module in case of
non-optimal distribution in the inlet pipes. With this device, the flow rate must not fall below 1000 l/h in the domestic
water mode (lower flow rates do not assure sufficient domestic water performance).
The second device (positioned in the brass hydraulic body: Figure 6) must be used if a further pressure drop increase is
required (this device only acts on the heating circuit and does not affect domestic water flow).
The circulating flow rate value is shown on the heat meter display (see §17).

7. OUTPUT/PUMP HEAD PERFORMANCE (only for models with pump: RP/1 – RSP – R2Z - RS2Z)
These models are fitted with a circulation pump.
This silent-running high-head pump is suitable for use on any type of heating system.
The pump, mounted inside the appliance, is fitted out for operation at maximum speed (III). Speed I should not be used
as flow rate/head performance does not satisfy normal operating conditions.
make sure the circuit pressure drops downline from the module are compatible with the supplied pump. In this case, the
column pump must only offset the circuit pressure losses upline from the module (a residue head is acceptable).
The circulating flow rate value is shown on the heat meter display (see §17).

Models R/1 – RP/1 – R2Z can house a meter for measuring the consumption of hot water from a centralised storage
system and another meter for measuring the consumption of cold domestic water of each user.
Models RS – RSP – RS2Z can house a meter for measuring the consumption of domestic hot water or total domestic
water consumption (hot water + cold water).
In the first case, the blind cap on the hydraulic assembly must be moved from the lateral connector to the cold water inlet
(ES). In the second case, the cap must be removed.
The kits comprise a SIEMENS WFH36 electronic volumetric meter with display and radio data transmission (featuring the
same characteristics as the heat meter: see §17) and two connection pipes housed inside the frame of the user module
in the holes made for that purpose.
For further information on the meter, see the supplied SIEMENS instructions.

HEAT METERING
17. HEAT METERING
The modules are supplied standard with a SIEMENS MEGATRON electronic heat meter.
This device measures heat consumption in the zone controlled by the user module.
The electronic unit features an 8-digit LCD display. The 3 Vdc input voltage is provided by a lithium battery (lifetime 8
years). A button for querying the appliance is located on the front of the display.
The appliance can be turned by 360° and inclined by 90°.
The appliance display has two levels with which the following information can be shown:

The units of measurement are °C or K, kWh, m3/h, kW, and hours.
The display shows total heating consumption by default.
Fault signals
The appliance automatically carries out diagnostic controls and displays the faults it finds. It divides the faults into two
cat- egories.
Temporary faults that do not cause operating problems. In this case, the display flashes for 32 seconds and then resumes
normal operation;
Major faults that stop the appliance. In this case, the display alternatively indicates the fault code and the date on n which
it appeared for the first time. The flows metered up until that moment, remain memorised.
0606_1021
For further information, see the supplied SIEMENS instructions supplied with the meter.
Figure 14: Meter display
Metering data can also be transmitted via radio to a remote reception device (Radio system expansion).
INSTALLATION AND OPERATING MANUAL

912.808.1 - IT
18. AUTOMATIC MEASUREMENT SYSTEM VIA RADIO
This system allows all the consumption data of the building to be handled from a single station, thus reducing measurement times whilst protecting user privacy. Transmission frequency is the 868 MHz established by the national radio transmission plan (European standard). The duration and power of the radio signal are irrelevant and are in no way connected
with prob- lems of “electro smog”.
The heat meters of the various user modules transmit consumption via a radio signal and the relative floor aerials (WTT16)
which receive and save the data. Consumption can be read by connecting a Personal computer to any of the floor aerials
via radio or making a cable connection to an aerial with a serial output or using a remote modem (GSM).

Following a heat demand from the ambient thermostat, the water from the centralised system begins to circulate in the
heating elements of the zone controlled by the user module.
For dual-zone models (R2Z – RS2Z) the heating bands of two zones can be managed separately by the relative ambient thermostats (or with the ECO CRONO climate adjustor).
For models RS – RSP – RS2Z (with plate exchanger), when a domestic hot water tap is opened, the user module heats
the water at the temperature set by the relative DHW potentiometer. TS temperature range: 30 ÷ 60°C (see § 16).
Different adjustments of domestic hot water temperature can be made directly using the ECO CRONO climate adjuster.
21.2 PARTIAL SHUT-DOWN
Adjust the ambient thermostat / heating programmer / ECO CRONO climate adjuster to disable the heating function (lower the set ambient temperature or disable heating). The domestic hot water function (models RS – RSP – RS2Z) and the
frost protection device (only for RS – RSP – RS2Z) remain active).
21.2 TOTAL SHUT-DOWN
Disconnect the appliance from the power supply by turning the luminous switch and the two-pole switch.
