OPERATING INSTRUCTIONS FOR THE USER
THE GAS SAFETY (INSTALLATION AND USE) REGULATIONS
1996. It is the law that all gas appliances are installed by a
registered person, in accordance with the above regulations.
Failure to install appliances correctly could lead to prosecu-
tion. 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 supply of 240 V - 50 Hz fused at 3 A is required.
Read these instructions carefully before attempting to oper-
ate the appliance.
1.1 INTRODUCTION
The Sime “MURELLE HE 25/55 - 30/55” family is a fully
automatic, wall mounted, room sealed, fan assisted range of
combination boilers.
The D.H.W. storage tank allows a variety of requests to be
met thanks to the abundance of water.
When operating in summer mode, the central heating is not
operational however the appliance continues to supply hot
water whenever it is required.
1.2 APPLIANCE OPERATION
Priority is given to the domestic hot water unless this is on a
separate time control.
On demand, domestic hot water is supplied from the internal
cylinder at the storage temperature. The initial 55 litres will
be at storage temperature. after this the water tempera-
ture will alter according to the flow rate (see 1.3 on page 5
of the installation guide).
When the demand ceases the cylinder will be heated to the
desired storage temperature, then if required the central
heating will resume.
1.3 OPERATING INSTRUCTIONS
1.3.1 Boiler ignition (fig. 24)
The first ignition of the boiler must be carried out by qualified
technical personnel. Successively, if it is necessary to start
up the boiler again, adhere strictly to the following instruc-
tions: open the gas tap to allow the flow of the fuel.
Move the mains supply switch of the system to “ON”.
A sequence of checks will be carried out and the display
shows as in fig 24, indicating the pressure of the system.
Correct functioning is indicated by the presence of a blue
luminous bar.
Winter
Press the key of the controls (pos. 2) to activate the win-
ter mode functioning (heating and D.H.W.). The display will be
as shown.

1.3.2 Regulation
C.H. temperature (fig. 25)
To set the temperature of the water
for heating, press the key of the
controls (2).
The first time the key is pressed, the
SET of heating circuit 1 is selected.
The second time it is pressed, the SET
if second zone fitted is selected. The
display will be as shown in figure 25.
Change the values with the key

The standard display will return If the
is pressed again, or after 10
seconds if no key is pressed.
Regulation of the external sensor
If an external sensor is installed, the
value of the output temperature is
automatically chosen by the system,
which quickly adjusts the environmen-
tal temperature on the basis of the
external temperature.
If you wish to change the value of the
temperature, increasing or decrea-
sing that calculated automatically by
the electronic card, proceed as indica-
ted in the preceding paragraph. The

1.3.4 To switch off the
boiler (fig. 24)
In the case of a short absence, press
the key of the controls (pos. 2). The
display will be as shown in the fig. 24.
In this way, leaving the electricity and
the fuel supply connected, the boiler is
protected from frost and from the
pump becoming jammed.
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 tap and, if low tempera-
tures are expected, to completely
empty the hydraulic circuits to avoid
pipes being frost damaged.

Setting the time
The time of day can be set by grasping
the outer edge of the black dial and
turning it in a clockwise direction until
the correct time is in line with the white
pointer.
Setting the “switching time”
The “ON” periods are set by sliding the
blue tappets, adjacent to the time peri-
ods required, to the outer edge of the
dial.
The tappets that remain at the centre
of the dial will be the “OFF” periods.
N.B.: The smallest switching time (ON
or OFF) is 15 minutes.
– To select “Timed” mode move the
selector switch in the middle of the
clock face to the “”position.
– To select “Constant” mode move
the selector switch in the middle of
the clock face to the “I” position.
– To select “OFF” mode move the
selector switch in the middle of the
clock face to the “O” position.

When the selector is in the “AUTO” position, boiler func-
tioning is automatically controlled on the basis of the
temperature levels and time periods set. The second
selector must be in the “RUN” position to start.
The programming procedure is described below:
–Setting the time
Set the selector to the “CLOCK“ position. Press “h” to
change the hour on the display, or “m” to change the
minutes. To set the day, press the “1…7” button until
the arrow is pointing to the correct day (1 =
Monday… 7 = Sunday).
–Setting the program
The time clock has 8 on times and 8 off times. To
make it easier to use, the time clock is supplied with
3 on times and 3 off times already set for each day
of the week, as shown below:
To select programmes other than those already set,
move the selector to position “P”; “0:001” will appear
on the display, in which the first three digits indicate
the hour and minutes, while the fourth digit identifies
the program number. Odd-numbered programs iden-
tify requests for operation (day temperature), in
which case the light bulb symbol will appear on the
display, while even-numbered programs identify
drops in temperature (night). Use the “1…7” key to
select the day of the week (from 1 to 7) or days (1 ÷
5, 6 - 7; 1 ÷ 6 or every day if the program is to be
repeated every day of the week). Set the hour and
minutes with the “h” and “m” buttons.
Press “P” to store the operation in memory and go
on to the next program. Repeat the same procedure
to set the remaining programs.
When finished programming, set the selector to
“RUN” position.
–Deleting one or more programs
The on and off time must be deleted for each pro-
gram to be deleted.
Set selector (2) to position “P”. Select the desired
program with button (3), then press button (4) to
delete the day setting (the triangular symbols for the
days should go away). If part of the program is dele-
ted, when you set selector (2) back to the “RUN”
position an error will appear in the clock display,
referring to the program which is incorrect.
To delete all programs, put the selector in position
“P” and press buttons (3) and (5) at the same time.
–Setting the SKIP function
The SKIP function deactivates programs for the next
day and resumes regular programming 24 hours
later.
This function is useful if you will be out all day and
don’t need heating.
To start this function, press button (7), which is acti-
ve only when selector (2) is in “RUN” position.
Once you have selected the SKIP function, it will go
into effect at 0:00 of the next day for 24 hours.
You cannot turn it off once it has started, so regular
programming will not resume until 24 hours have
passed.
