Engineer, and recorded in the installation manual.
• The appliance must be registered with both Sime Ltd and Gas Safe within 30 days of installation.
• The appliance must be serviced annually, by either Sime Ltd or a Gas Safe registered engineer- ensuring that the
Benchmark service record in the installation manual is completed.
Failure to comply with the above will result in only the 12 month warranty being offered.
In the absence of any proof of purchase, the 12 month warranty period will commence from the date of manufacture

se safety, efficiency and performance.
Benchmark is managed and promoted by the Heating and Hotwater Industry Council.
For more information visit www.centralheating.co.uk
Please ensure that the installer has fully completed the Benchmark Checklist in the use and maintenance section
of the installation instructions supplied with the product and that you have signed it to say that you have received a
full and clear explanation of its operation.
The installer is legally required to complete a commissioning checklist as a means of complyng with the appropria-
te Building Regulations (England and Wales).
All installations must be notified to Local Area Building Control either directly or through a Competent Persons

OPERATING INSTRUCTIONS FOR THE USER
THE GAS SAFETY (THE GAS SAFETY
(INSTALLATION AND USE) REGULA-
TIONS 1996.
It is the law that all gas appliances are
installed by a Gas Safe Registered engi-
neer, in accordance with the above reg-
ulations. Failure to install appliances
correctly could lead to prosecution. It is
in your own interest, and that of safety,
to ensure that the law is complied with.
It is essential that the appliance is
correctly earthed. An electricity sup-
ply of 240 V - 50 Hz fused at 3 A is
required.
Read these instructions carefully
before attempting to operate the appli-
ance.
1.1 INTRODUCTION
The Sime “ECOMFORT PLUS 25 HE -
EV” , “ECOMFORT PLUS 30 HE -EV”
and “ECOMFORT SYSTEM PLUS 25
HE -EV” are fully automatic, wall mount-
ed, room sealed, fan assisted boilers.
When operating in winter mode, the
appliance provides central heating as
required and the combination versions
produce instantaneous hot water upon
demand. When operating in summer
mode, the central heating is not opera-
tional however the appliance continues
to supply hot water whenever it is
required.
The heat output is automatically con-
trolled by the fully modulating gas valve
(within its pre-set limits).
A temperature/pressure gauge is fit-
ted and an overheat thermostat is
incorporated to protect against fault
conditions.
1.2 APPLIANCE OPERATION
(COMBINATION VERSION)
A demand of hot water will be sensed
by the appliance detecting water flow
(providing that the flow rate is above 2
l/m - 0.5 gal/min).
The fan will start and the burner will
light at full output. If the draw off rate
is near the maximum design flow
rate the appliance will run continu-
ously at full output until a tap is either
turned off or the flow rate is reduced
in which case the heat output will
reduce accordingly to maintain a
steady temperature.
Hot water is made available almost
immediately at the appliance outlet,
but the final temperature and time
taken for the hot water to reach a tap
depends upon the potentiometer set-
ting, the rate at which water is drawn
off, and the length of the pipe between
the boiler and the tap.
When the tap is turned off, the appli-
ance will revert to C.H. mode (if set on
winter position) otherwise the burner
will be extinguished pending the next
demand for hot water.
BOILER IGNITION (fig. 1)
The first ignition of the boiler must be
carried out by qualified technical per-
sonnel.
Successively, if it is necessary to start
up the boiler again, adhere strictly to
the following instructions: open the
gas tap to allow the flow of the fuel
and move the main switch of the
system to “ON”.
Wait for about 30
seconds before restoring functioning
conditions so that the boiler can
perform the control sequence.
If the green led is on, this indicates the
presence of voltage.
Keys lock
If the device is not used, the keys will be
locked 15 minutes after the last set-
ting was made (PAR 5 by default) and
the display light switches off.
To set one of the operating modes,
press any of the keys for more than
two seconds (the display will indicate
one to four segments progressively
before unlocking the controls).
Winter
Press the key of the controls to
activate the winter mode functioning
(heating and D.H.W.). The display will
be as shown in the figure.
Summer
Press the key of the controls to
activate the summer mode functioning
(only the production D.H.W.). The
display will be as shown in the figure.
Fig. 1
ATTENTION: Use the keys to alter the value of any function, a beep indicates that the key was
touched and the function is activated. After 15 minutes the display will turn off (PAR 5).

REGULATION OF THE WATER TEM-
PERATURE FOR HEATING (fig. 2)
To set the temperature of the water
for heating, press the key of the
controls .
The display will be as shown in the figu-
re. Change the values with the key (
and ). The adjustment will be
accepted by pressing the key
again, or after 10 seconds if no key is
pressed.
Regulation of the external
sensor (fig. 2/a)
If an external sensor is installed, the
value of the output temperature is
automatically chosen by the system,
which quickly adjusts the of flow tem-
perature on the basis of the external
temperature. If you wish to change the
value of the temperature, increasing
or decreasing that calculated automa-
tically by the electronic card, proceed
as indicated in the preceding para-
graph. The level of various correction
of a value of temperature proportional
calculated. The display will be as
shown in fig. 2/a.
REGULATION OF THE D.H.W.
TEMPERATURE (fig. 3)
To set the desired temperature
D.H.W., press the key of the con-
trols. The display will be as shown in
the figure. Change the values with the
key ( and ).
The adjustment will be accepted by
pressing the key again, or after 10
seconds if no key is pressed.
TO SWITCH OFF THE BOILER (fig. 4)
In the case of a short absence, press
for more than two second the key
of the controls. The display will be as
shown in figure (boiler in stand-by). In
this way, leaving the electricity and the
fuel supply connected, the boiler is pro-
tected from frost and from the pump
becoming blocked.
If the boiler is not used for a prolonged
period, it is advisable to disconnect the
electricity supply, by switching off the
main switch of the system, and to
close the gas isolation valve and, if low
temperatures are expected, to com-
pletely empty the hydraulic circuits to
avoid pipes being frost damaged.
