GENERAL SAFETY INFORMATION
a Do not allow children or
infirm persons to operate
the boiler unsupervised.
a Do not operate any electri-
cal devices or equipment,
including switches or domestic
appliances, etc., if you can smell
fuel or fumes. If you detect any suspicious smells:
- Ventilate the room by opening all doors and win-
dows.
- Close the fuel shut-off cock.
- Report the fault immediately to THERMITAL’s
Technical Assistance Service or a professionally
qualified heating engineer.
a Never clean or service the boiler without first discon-
necting it from the mains electricity supply by turning
the main power switch OFF.
a Never pull, disconnect, or twist the electrical cables
coming from the boiler even if it is disconnected
from the mains electricity supply at the time.
a Do no obstruct or restrict the vents in the room
where the boiler is installed. Adequate ventilation is
essential for correct combustion.
a Do not store containers of flammable substances in
the room where the boiler is installed.
a Do not touch the boiler when bare-
foot or wet.
a Do not switch the boiler off
if outside temperature drops
below ZERO (risk of free-
zing).
b This instruction manual and that for the installer
and Technical Assistance Service are integral parts
of the boiler. They must be kept safe and must
ALWAYS accompany the boiler, even if it is sold
to another owner or user or transferred to another
installation. If you damage or lose this manual,
order a replacement immediately from your local
THERMITAL Technical Assistance Centre.
b This boiler must be installed by a
legally qualified heating engi-
neer (in Italy heating engine-
ers are regulated by law 46
of the 5th March 1990.) On
completion of the installation,
the heating engineer must
issue the owner with a declara-
tion of conformity confirming that
the installation has been completed t o
the highest standards in compliance with the instruc-
tions provided by THERMITAL in this instruction
manual, and that it conforms to all applicable laws
and standards.
b If you notice any water leaking from the boiler,
disconnect it immediately from the mains electrici-
ty supply, shut off the water supply, and notify your
local THERMITAL Technical Assistance Centre or a
qualified heating engineer immediately.
b Periodically check that ope-
rating pressure in the water
circuit is over 1 bar. If water
pressure is consistently
low, contact THERMITAL’s
Technical Assistance Service
or a professionally qualified
heating engineer.
b If the boiler is not going to be used for an extended
period of time, proceed as follows to prepare it for
shutdown.
- Turn the mains power switch OFF.
- Close the boiler’s fuel cock and water cock.
- Drain the central heating circuit if there is any risk
of freezing.
b The boiler must only be used for the purpose spe-
cified by THERMITAL and for which it is designed.
The manufacturer declines all responsibility, con-
tractual or other, for damage to property or injury to

START-UP
Have THERMITAL’s Technical Assistance Service start-up your boiler for the first time. Once this has been done, the
boiler can be left to function automatically. Under certain circumstances, such as after long periods of disuse, the user
may need to re-start it without involving the THERMITAL’s Technical Assistance Service. Before doing so, perform the
following checks and operations.

SETTING DOMESTIC HOT WATER TEMPERATURE
b To set domestic hot water temperature, make
sure that no central heating zone is requesting
heat (the “Ot” message must not be visible
on the boiler display). Make sure that there is
no bridge between terminals 23-24, 26-27 and
29-30. Also make sure that no central heating
zone is requesting heat via Open Therm. Under
this condition, the CH circuit (BAG) control card
passes control to the boiler control card, permitting
adjustment of DHW temperature (which is control-
led by the boiler control card).
To adjust the temperature of the domestic hot water
(bath, shower, washbasins, etc.), turn the knob with the
“Å” symbol. Turn the knob clockwise to increase water
temperature or anti-clockwise to reduce it. The digital
display reads out the new temperature setting as you turn
the knob. The adjustment range for DHW temperature is
between 35 and 60 °C. The display always reads out the
setting as you adjust water temperature, both for central
heating water and domestic hot water. Once you have set
the desired temperature, the setting is memorised after 4
seconds and the display once again reads out the actual
temperature of the CH flow or DHW as detected by the
temperature sensor.
b If an REC 07/08 remote control is installed, DHW
temperature MUST be adjusted from the remote
control (see the specific instructions provided
with the remote control).
STARTING UP THE BOILER
If a timer or room thermostat is installed, these must be
switched on and adjusted to a temperature higher than
current room temperature before the boiler can start up.
The boiler will remain in stand-by mode until the burner
ignites following a request for heat. The green LED (2) on
the left of the control panel lights to show that the burner
is lit and the message "Ot" (OpenTherm) is displayed to
indicate that the burner control card is dialoguing with the
CH circuit control card.
The boiler will carry on functioning until the set tempera-
tures are reached, when it will return to stand-by mode
while continuing to display the central heating flow tem-
perature.

If any ignition or functioning errors occur, the boiler per-
forms a “SAFETY SHUTDOWN”. The green LED on the
control panel goes out and an error code flashes on the
display. The red LED (3) indicates a burner lock-out. See
the “WARNING LEDS AND ERRORS” section for details
on the various error codes and how to reset the boiler.
RESET FUNCTION (burner control card)
To reset the boiler, turn the function selector to “É”, then
return it to its previous position and check that the red
LED goes out.
Provided correct functioning conditions have been resto-
red, the boiler restarts automatically. As soon as the bur-
ner ignites the green LED lights and the digital display will
read out current operating temperature.
b Turning the function selector to “É” without retur-
ning it to “b”, will not reset the boiler.
If the boiler does not restart after a number of resets, call
your local Technical Assistance Centre.
Under normal conditions, when the function selector is
turned to “É”, the digital display reads out “- -” unless
the frost protection function (AF) is active, or combustion
analysis (CO) in being performed.
RESET FUNCTION (BAG CH circuit control card)
The BAG control card can only be reset from the REC
07/08 remote control (if present) or from a PC running
dedicated software.

SHUTDOWN
If you are going away for a short period of time like a
weekend or a short holiday, etc., turn the function selector
to “É“ OFF/RESET.
The digital display reads out the message shown alongside.
Because electrical power and the gas supply to the boiler
both remain on, the boiler is protected by the following
systems:
- The boiler frost protection function that protects the
heat exchanger if outdoor temperature falls below -5 °C
during total shutdowns.
b The message AF flashes on the display for as long
as the frost protection function remains active.
- The CH circuit frost protection function that protects
the mixing column and the mixed CH circuits against
the risk of freezing. The mixed CH circuit temperature
sensors protect only the low temperature circuits: the
“BAG” card’s own sensor protects the high temperature
circuit. If the temperature detected by any one of the
sensors (mixed circuit or BAG) falls below 10°C, the
pump for the circuit concerned is switched on for a time
determined by the setting of the "FROST PROTECTION
TIME" parameter. If temperature rises above the 10°C
threshold during this time, the pump is switched off.
If temperature has not risen above 10°C by the end
of “FROST PROTECTION TIME”, but has not dropped
below the "FROST PROTECTION THRESHOLD", cir-
culation is re-activated for 4 minutes after 2 hours. If
on the other hand temperature falls below the "FROST
PROTECTION THRESHOLD" (irrespective of when or
how) a request for heat is generated and the boiler runs
at minimum power until the temperature detected by the
sensor (mixed circuit/BAG) rises above 10°C.
- The anti-seize function that opens and closes the mixer
valve (if fitted) and the circuit pump for 10 seconds, at
intervals determined by the setting of the "ANTI-SEIZE
INTERVAL" parameter. This function serves to prevent
seizure of the pump rotor.
If the boiler is not going to be used for an extended period
of time, proceed as follows to prepare it for shutdown.
- Turn the function selector to OFF/RESET.
- Turn the mains power switch OFF.
- Close the fuel shut-off cock and the central heating and
DHW circuit shut-off cocks.
Note that the frost protection and pump anti-block fun-
ctions are not active under these conditions. Drain the
central heating circuit and domestic hot water circuit if
there is any risk of freezing.
