Clock Instructions - E-COMBI

1. General layout

The mechanical clock covers a 24 hour period. Each tappet repre-

sents 15 minutes A. An override switch is located on the clock B.

2. To set the time

To set the time of day, grasp the outer edge of the dial and turn slow-

ly clockwise until the correct time is lined up with the arrow C.

3. To Set the "On" and "Off " times

The clock uses a 24hours system. e.g. 8 = 8.00 am and 18 = 6.00 pm

"ON" periods are set by sliding all tappets between the "ON" time and

the "OFF" time to the outer edge of the dial.The tappets remaining at

the centre of the dial are the "OFF" periods.

4. For operation

Put the selector switch B to the

heating by the clock. Put the switch B to "I"

to select permanent operation or to "0" to turn the central heating off

permanently.

Boiler protection devices

The boiler is protected from malfunctioning by means of internal

checks performed by the electronic microprocessor P.C.B., which

stops the boiler from operating if necessary.

In the event of the boiler being shut off in this manner, the LED shows

the type of shut-off and the reason behind it.

There are two types of shut-off :

Safety shut-off

This type of error is "volatile", which means that the boiler starts up

again automatically as soon as the problem which caused the shut-off

is removed; the yellow LED 9 ﬂashes and the C.H. temperature LED 1

indicate the error code. (see table)

As soon as the cause of the shut-off disappears, the boiler starts up

again and continues to operate normally.

If the boiler still indicates a safety shut-off , switch it off . Make

sure the external electric switch is in the OFF position and contact

a qualifi ed technician.

Shutdown due to insuffi cient water circulation

If the green leds 1 ﬂash and the boiler is off , one possible cause for this

state is an insufficient pressure of water in the system - green LED 40-

50 blink. Check the water pressure on the pressure gauge 4 and make

sure that is between

0.6 and 1.5 bar when

the system is cold. If

the pressure is just

under the minimum

reﬁll the system by

opening

the

valve

under the boiler.

If the pressure drops

very frequently, there

may be a water leak

at some point in the

system. If this is the

case a plumber should

be contacted.

Operation shutdown

This type of error is "non-volatile", which means that it is not removed

automatically (the red LED 8 will illuminate and the C.H. temperature

LED 1 will indicate the error code). In this case the boiler does not

restart automatically, but it may be reset by pressing the

button. If the problem manifests itself again after several attempts to

reset the appliance, contact a qualiﬁed technician.

Important

If this shutdown occurs frequently, contact an authorised service

centre for assistance. For safety reasons, the boiler will allow

a maximum of 5 reset operations to take place in 15 minutes

(individual presses of the button). If the shutdown is occasional

or an isolated event, this is not a problem.
