9 Long periods of inactivity of the equipment imply the fol-
lowing operations to be carried out:
−Set the main switch of the equipment to “0”
−Set the main switch of the system to “OFF”
−Close the fuel valves and the water valves of the thermal
system
−Drain the central heating circuit if there is any risk of
freezing.
9 The product must be serviced at least once a year. Servicing
must be arranged in advance with the RTechnical Assis-
tance Service.
9 This manual is an integral part of the appliance and must
therefore be kept with care and must ALWAYS accompa-
ny the boiler, even when it is passed on to another own-
er or user or transferred to another installation. If it is lost
or damaged, please contact your local Technical Assistance
Service Rfor a new copy.
9 This manual must be read carefully so as to ensure the cor-
rect and safe installation, operation and maintenance of
the appliance. The Owner must be adequately informed
and trained on how to operate the appliance. Make sure
that he/she is familiar with all the information required for
safe system operation.
9 We recommend cleaning inside the exchanger once a year,
extracting jet and burner and removing any installation de-
bris by suction. This operation should be done by personnel
from the Technical Assistance Service only.
1.2 Precautions
The operation of any appliance that uses fuel, electrical power
and water demands that a number of fundamental safety pre-
cautions be respected:
0 Do not allow children or inrm persons to operate the sys-
tem unsupervised.
0 It is forbidden to use electrical devices or equipment, such
as switches, appliances, etc. if there is a smell of gas or un-
burnt products. If so:
−Ventilate the room, opening doors and windows
−Close the fuel shut-off cock
−Report the fault immediately to the R's Technical As-
sistance Service or a professionally qualied heating en-
gineer.
0 Do not touch the boiler while barefoot or wet.
0 Do not plug or block the condensate drain outlet.
0 Never pull, disconnect, or twist the electrical cables coming

GENERAL INFORMATION
1.3 Description of the appliance
The condensing thermal unit TAU Unit is a hot water generator,
with high thermal efciency, for the heating of environments
and production of domestic hot water (DHW) coupled to an ex-
ternal heater.
The boiler body is in high alloy stainless steel and develops ver-
tically ensuring maximum duration and reliability, meeting at
the same time the most stringent national and European reg-
ulations on the emission of heavy metals in condensate drain
waters.
The double return hydraulic circuit (high or low temperature) fa-
vours temperature stratication inside the body and optimises
the performance.
The boiler body is covered in high density glass wool insulation
to reduce heat loss.
The pre-mixed microame burner with power modulation ratio
1:10 ensures low polluting emissions (NOx and CO) in compliance
with the most stringent European Regulations.
The thermoregulation with user interface and display in the
control panel TAU Unit allows managing the safety and control
devices in compliance with current regulation. By connecting
the external probe it is possible to activate the climatic control
function of the heating circuit, enhancing the seasonal energy
recovery characteristics.
The thermoregulation adapts with exibility to the different sys-
tem needs; for example, it is possible to increase the number
of heating circuits supplied with high and low temperature and
connect the devices TAU Unit in cascade (see accessories Cata-
logue).
1.4 Safety and control devices
The thermal unit TAU Unit is equipped with the most advanced
safety and regulation systems available on the market.
Each fault is signalled through a numeric error code displayed
on the screen and stops the equipment causing the automatic
closure of the gas valve.
The following are installed on the water circuit:
−Safety thermostat: on the body of the generator, it inter-
venes to stop the appliance if the temperature exceeds
the threshold limit of 110°C.
−Delivery temperature probe: immersion probe on the
delivery line of the generator is used by the regulator
to view and check the delivery water temperature and
check the correct switching on and off of the equipment
based on the programmed setpoint. The regulator uses
the same probe to stop the generator in case of overtem-
perature, before the triggering of the safety thermostat.
−Return temperature probe: the contact probe placed
on the return line of the boiler is used by the regula-
tor to view the return water temperature with which it
calculates, together with the delivery temperature, the
temperature difference between delivery and return (∆t),
which allows regulating the modulation of the thermal
unit circulation pump in heating mode.
−Flue gas thermostat: placed in the lower part of the
exchanger, it triggers with high ue gas temperature
(>75°C).
−Flue gas probe: placed in the lower part of the exchang-
er, causes a temporary error if the temperature of the
combustion products exceeds 85°C, and a permanent
error if it exceeds 90°C.
Through specic inlets and outlets, the thermoregulation TAU
Unit allows managing the following optional safety devices out-
side the equipment:
−Pressure transducer or water minimum pressure switch:
the connection of one of the two optional devices, to be
carried out by the installer, allows the thermoregulation
to continuously view and check the pressure of the pri-
mary circuit to start or stop the equipment in case of low
pressure.
−LPG fuel shut-off solenoid valve: the thermoregulation,
via a programmable output, allows managing (based on
the designated type of fuel and system) the fuel shut-off
solenoid valve for LPG, installed outside the equipment
by the installer.
−Gas minimum pressure switch: a specic outlet is pres-
ent for the connection of the gas minimum pressure
switch (optional) to be installed outside the equipment.
The device will continuously check the correct inlet gas
pressure to start or stop the equipment in case of low
pressure.
9 The triggering of the safety devices indicates a potentially
dangerous malfunctioning of the equipment. Therefore,
immediately contact the Technical Assistance Service.
9 Safety devices must be replaced by Technical Assistance
Service, using only original parts. Refer to the spare parts
catalogue supplied with the appliance. After the repair per-
form an ignition test and check that the equipment works
correctly.
0 The appliance must not be put in service, even temporarily,
when tampered safety devices are not in operation or have
been tampered with.

2.1 Putting into service
9 The appliance must be maintained and adjusted at least
once a year by Technical Assistance Service or by profession-
ally qualied staff in compliance with all applicable Nation-
al and Local provisions.
9 Incorrect maintenance or adjustment may damage the ap-
pliance and cause damage to people or create a hazard.
9 The system manager is forbidden from opening and remov-
ing the appliance's casing. These activities must be carried
out only by Technical Assistance Service or by professionally
qualied personnel.
The thermal module TAU Unit Rmust be commissioned by
Technical Assistance Service R, after which step the appliance
may operate automatically.
However, the system manager may be required to restart the
appliance independently, without involving Technical Assistance
Service; for example after a long period of absence.
To do so, perform the following checks and operations:
−Check that the fuel valves and the water valves of the
thermal system are open
−While the system is still cold, check that working pressure
in the central heating circuit is over 1 bar but below the
maximum limit specied for the boiler
−Adjust the room thermostats for the high and low tem-
perature zones to the required temperature (~20°C) or,
if the systems are equipped with timer thermostats or a
time programming unit, make sure it is on and adjusted
(~20°C)
−Switch the system's master switch to the ON position and
the thermal module's master switch to (I).
The appliance will go through the switch-on stage and, after
starting, it will continue to operate until set temperatures are
achieved.
The burner will then switch off and on automatically to main-
tain the set temperature without further operator action.
In the event of ignition or operation faults, the display will show
a numeric error code that will enable the user to interpret the
possible cause as detailed in Paragraph "Error List".
9 In the event of a permanent error, to reset starting condi-
tions press the "RESET" key and wait for the thermal module
to restart.
Repeat this operation 2-3 times at the most. If the problem per-
sists after that, call R’s Technical Assistance Service.

USE
2.2 Switching the appliance on and off
After switching the appliance on, the display shall look as shown
in the gure below:
04:29
12.0 ”°C”
“CH Setpoint”48.0”°C”
External temperature is shown on the display on the left. This
value is displayed only if the outdoor temperature sensor (ac-
cessory) is installed.
Main setpoint values are shown in the lower side of the display
while the time is shown on the top right side.
To turn the equipment off set the main switch “0/I” that is
placed on the back side to “0”.
9 Never power off the appliance before switching the master
switch to the "0" position.
9 Never switch off the appliance with the master switch if a
request is active. Always make sure that the appliance is in
stand-by before switching the main switch.
2.3 Ignition failure
If an anomaly of ignition or operation occurs, a variable mes-
sage will be indicated on the display of the command interface
based on the anomaly found.
Try to manually reset the device by holding down the key "RESET"
(1).

2.7 Scheduled programme
The Scheduled Programme is designed to program the opera-
tion of the various circuits managed by the thermal module, (CH,
DHW and additional mixed zones).
Seasonal Programme
The Seasonal Programme is use to exclude additional mixed
zones during the summer season.
It does not control any DHW parameter.
Holiday Programme
The Holiday Programme is used to exclude part of or all the cir-
cuits at a certain time of the year.
A holiday can be set both on the full system and on various
groups of circuits.
The group system enables the user to add various circuits to the
group to set a holiday period for several circuits at the same
time. (For instance, to manage a semi-detached house with a
centralised heating system when one of the two families is on
holiday and the other is not).
The set-point type can be adjusted so as to correspond to the
desired setting.
The system can control up to a total of 16 "Mixed" zones. The
programming of mixed areas is only allowed with an accessory.
At the same time as these 16 areas, it is also possible to enable
the CH zone (direct zone for central heating only).
