Timeclock
The boiler can be switched on and off automatically by the built-in timeclock. To set the timeclock, proceed as
follows: (refering to diagram 1).
Press in the tappets corresponding to the time you want the boiler to be on.
For example if you want the boiler to be on between 7 AM and 9 AM, push in all the tappets between 7 and 9.
Set the times you want the boiler to be on for the rest of the day in the same way.
Note:
The timeclock setting is in 24 hour format. Therefore, if you want the boiler to come on at 2 PM you must
push in the tappets at 14.
To set the correct time rotate the clock by hand until the current time is indicated by the arrow at the top of the
clock.
To operate the boiler according to your selected times, place the grey lever to the position.
To have the boiler permanently ‘ON’, place the grey lever to the ‘I’ position.
To have the boiler permanently ‘OFF’, place the grey lever to the ‘0’ position.
Safety lockout
In the event of a safety lockout, the digital display will show ‘F1’.
Reset boiler by pressing the RESET button.
IMPORTANT:
If safety lockout occurs frequently, or if any other fault is indicated, contact your Installer/Service
Provider.
DRAINING AND FILLING
CAUTION:
The boiler is installed as part of a sealed system which must only be drained and filled by a competent
person.
If the pressure drops to 0.8 bar the pressure LED on the Bar button starts to flash. The boiler will continue to work,
but the LED warns that pressure in the CH system is on the low limit and CH system must be filled. To fill the
system, open the tap on the filling loop below the boiler. Press the Bar button to read the system pressure. When
the pressure is between 1 and 2 bar, close the tap.
Note
: If there is persistent loss of system pressure, you must consult your Installer/Service Provider.

CAUTION:
A safety valve with a discharge pipe is fitted to this boiler.
The valve
MUST NOT BE TOUCHED
except by a competent person. If the valve discharges at any time, switch
the boiler off and isolate it from the electrical supply. Contact your Installer/Service Provider.
SERVICING / MAINTENANCE
To ensure the continued efficient and safe operation of the boiler, it is recommended that it is checked and
serviced at regular intervals. The frequency of servicing will depend upon the installation conditions and usage
but, in general, once a year should be enough.
