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 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 supply of
240 V - 50 Hz fused at 3 A is required.

Read these instructions carefully before
attempting to operate the appliance.

1.1 INTRODUCTION

The Sime “MURELLE EV HE” family is a fully
automatic, wall mounted, room sealed, fan
assisted range of combination boilers.
When operating in winter mode, the appli­ance provides central heating as required
and produces instantaneous hot water
upon demand.
When operating in summer mode, the cen­tral heating is not operational however the
appliance continues to supply hot water
whenever it is required.

The Sime “MURELLE EV HE SYSTEM” fam­ily is a fully automatic, wall mounted, room
sealed, fan assisted range of system boil­ers. The appliance provides central heating
as required.

The Sime “MURELLE EV HE T” family is a
fully automatic, wall mounted, room sealed,
fan assisted range of system boilers. The
boiler is fitted with a divertor valve which
enables the boiler to be directly connected
to a hot water cylinder.

1.2 APPLIANCE OPERATION

“EV HE” - 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 continuously 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 setting,
the rate at which water is drawn of f, and
the length of the pipe between the boiler
and the tap. When the tap is turned off, the
appliance will revert to C.H. mode (if set on
winter position) otherwise the burner will
be extinguished pending the next demand
for hot water.

“EV HE”, “EV HE System” & “EV HE T” - a
demand for heating will be sensed by the
boiler, The pump will start, and provide suf fi­cient circulation is detected, the fan will
start and the burner will light. The heat out­put will be controlled by the heating sensor
and the user interface control.

1.3 OPERATING INSTRUCTIONS

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 peri­ods 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.

MECHANICAL TIME CLOCK - Code 8092228

Slide blue tappets

OUT for ON period

Slide blue tappets IN for OFF period

Mode selector switch

When the selector is in the “AUTO” position, boiler func­tioning 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 iden­tify 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 pro­gram 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 dele­ted, 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 acti­ve 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.
