The operational time periods may be set as
follows:
Rotate the clock actuator mechanisms
clockwise, by hand, until the small black
triangle indicates the current time, see
figure 5. In figure 5, current time is 21:05.
The timer uses 24 hour format, e.g. the
time for 1pm the time is 13:00 hrs.
Select the "On" times by pushing the black
tappets to the outside.
Select the 'Off' times by pushing the black
44
tappets towards the centre of the clock.
E.g. The clock shown in diagram 2 is set as
follows:
The clock operation can be set by a selection
switch.
The switch has 3 positions:
1 (Up) position: The boiler is controlled by the
function switch (Item 1 in Figure 3) and
allows continuous operation.
(Mid) position: The boiler heating circuit is
controlled by both function switch and clock
tappets, whilst hot water is delivered on
demand.
0 (Down) position: The boiler is off,
independent of the function switch.
FROST PROTECTION
The boiler has a built in frost protection device
that protects the boiler from freezing. If the
boiler is to be left and there is a risk of frost,
ensure that the gas and electrical supplies are
left connected. The frost protection device will
light the boiler when the temperature of the
boiler water falls below 6

thermostat setting and will protect the boiler, but
not necessarily the full system.

SYSTEM PRESSURE.
On installation your installer will have filled the
boiler and system to its effective working
pressure. The boiler's pressure sensor should be
regularly checked on the LCD to ensure that this
pressure is maintained between 1 and 2 bar. If
there is a significant loss in pressure the boiler
will lock out. The system may be re-charged by
opening the filling loop to charge the system back
up to 1.5bar as indicated on the LCD panel. DO
