D.H.W. temperature control The position of this
control dial will determine the temperature of the
domestic hot water delivered to the taps or
shower unit. The water temperature can be set
from a minimum of 35º C (anticlockwise stop
position) to a maximum of 64º C (clockwise stop
position.)
4.
Boiler On The boiler ‘Stand by’ indicator (green)
lights when power is supplied to the PCB.
5.
Water Temperature The temperature of the
water leaving the boiler is given by the red light
indicators situated alongside the burner 'Stand
by' indicator light.
6.
Fault Indicator The control unit has an in-built
fault diagnostic function. When a fault occurs, the
type of fault is indicated by the appropriately
'flashing' red light indicator. A listing of the
display lights and meanings can be found in
Section 13 of the Installation and Servicing
Instructions.
7.
Boiler Lockout When the first red light indicator
from right (flame or gas fault) or the second from
right (overheat fault) lights, the boiler will need to
re-set. To re-set the boiler the function switch
must be switched to the
position and after 30
seconds back to its previous (summer or winter)
position.
8.
Pressure gauge The pointer on the gauge
indicates the pressure within the boiler and
central heating system and should, when the
water is cold, read between 1 and 2bar.
If the pressure gauge falls below 1bar the system and
boiler must be re-pressurised via the filling loop. The
filling loop should be located below the boiler.
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
o
C. When
the temperature reaches 15
o
C, the boiler will shut
down.
Note: This device works irrespective of any room
thermostat setting and will protect the boiler,
but not necessarily the full system. Ensure that
vulnerable sections of the circuit are adequately lagged.
SYSTEM PRESSURE
On installation your installer will have filled the boiler
and system to its effective working pressure. The
boiler's pressure gauge should be regularly checked to
ensure that this pressure is maintained between 1 and
2 bar. If there is a significant or frequent drop in
pressure then your installer should be consulted.
OPERATING THE BOILER
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 LED 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 1.5 bar as indicated on the LED panel.
DO NOT OVERCHARGE THE BOILER PRESSURE
BEYOND 2 BAR AS THE BOILER WILL NOT OPERATE.
The filling loop, a flexible hose with two valves, should
be located below the boiler connecting the second pipe
on the right to either one of the outer pipes, see
Figure
10. DO NOT CLOSE ANY OF THE FOUR VALVES
DIRECTLY CONNECTING TO THE BOILER. If the boiler
frequently loses pressure then your installer should be
consulted.
CLEANING
The boiler casing may be cleaned with a damp cloth
followed by a dry cloth to polish. Do not use abrasive or
solvent cleaners.
FURTHER ADVICE
Note. A Service Engineer must be contacted if a boiler
fault continues to occur.
