41 COMMISSIONING
IMPORTANT . Domestic hot water circuits (if they
exist) and heating circuits must have been filled
and bled, and leak tightness tests must have
been carried out on them, in accordance with the
instructions for the domestic hot water calorifier
(if existing) and boiler.
Refer to the following instructions to start up the
boiler:
-
the instructions delivered with the burner.
- the instructions delivered with the domestic
hot water calorifier, (if existing).
1 Boiler on/off switch
Position ..... ON Position ..... OFF
2. Alarm light
Comes on when the burner is in safety lockout
3. Summer/Winter switch
W i n t e r Start the heating pump
Summer The heating pump stops 12 minutes
after the changeover to summer mode.
4. Test-STB button
When held in the pressed position it tests the safety thermostat
and cuts off the pump(s)
5. Safety thermostat (with manual reset) Set to 110
0

6. Timed circuit breaker (4A)
7. Electronic thermostat
Adjustment of the boiler flow temperature, 30 - 90
o
C
8. Light on
Indicates the display above it is showing the boiler flow
temperature
DOMESTIC HOT WATER
(combination boilers or those fitted with a DHW sensor)
Items 9 & 10 only.
9. Light on
Indicates the display above it is showing the DHW
temperature.
10. Electronic thermostat
Adjustment of the average DHW storage temperature,
10 - 80
o
C.
Notes for items 9 & 10 only.
Combination boilers or those fitted with a DHW sensor.
When the system is switched on it performs an air
elimination sequence of the hot water calorifier lasting for 1
minute, by intermittently operating the DHW load pump
and the CH pump. This air elimination sequence is de-
activated if the calorifier temperature is more than 25
0 C
Summer/Winter Switch . If DHW has been in demand, a
delay of approx. 1 minute will occur for the change from the
DHW pump to the CH pump, after the changeover to
Winter mode.
MESSAGES - ALARMS
The display may show the following messages in the case of a malfunction:
Notes
Probable Cause
The corresponding
sensor circuit is
interrupted or is short
circuited If the power supply is interrupted with
an
alarm and no corrective action
is taken then, when the power is
resumed, the boiler will restart but
continue to operate in a C
H mode only
and alarm
will NOT be displayed.
The titanium anode is
open circuit or the
calorifier is empty
The titanium anode
has a short circuit or
the connections are
wrong
(+ve to -ve or vice versa)
The DHW may be reactivated for 24 hours
by disconnecting and reconnecting the
power supply to the boiler.
If the titanium anode is faulty the
calorifier will no longer be protected. It
is therefore absolutely vital to inform
the installer or engineer in charge of
maintaining the boiler.
If the calorifier is not fitted with a
titanium anode check that the
connector supplied in the AD 212 kit,
which has a 22Ohm resistance and a
100nF capacitor fitted, is correctly
connected to terminals 25 and 26.
