COMMISSIONING
(e) Lock out fault Code mode: In this mode the lockout fault codes are displayed.
The button B1 is used to select this mode and the button B2 is used to cycle
between the stored faults. The fault code reading is displayed by alternatively
flashing the fault number and the internal error number.
There are 16 fault codes stored in order of occurrence. The fault code ‘C0’ is the
current or last fault code and the fault code ‘CF’ is the previous fault.
When no fault is stored at the displayed fault number, an ‘FF’ is displayed. It is also
possible that ‘EE’ is displayed for an internal error number. This means that the
controller is busy reading the memory. The lockout error codes are listed in table
5.7.
The locking errors can be cleared by pressing the reset button B1.
(f) Block out fault code mode: In this mode the block out fault codes can be
displayed. The button B1 is used to select this mode and the button B2 is used to
cycle between the stored faults. Fault code reading is displayed by alternatively
flashing the fault number and the internal error number.
There are 16 fault codes stored in order of occurrence. The fault code ‘c0’ is the
current or last fault code and the fault code ‘cF’ is the previous fault.
When no fault is stored at the displayed fault number, an ‘FF’ is displayed. It is
also possible that ‘EE’ is displayed for an internal error number. This means that
the controller is busy reading the memory. The block out error codes are listed
in table 5.8.
Blocking errors are displayed as a non blinking number, with or without a dot. The
error will be reset when the fault is cleared. To reset some internal errors switch
power off, wait 10 seconds and switch power on again.
(g) Non Blocking or Locking Errors
These are displayed as a blinking number with or without a dot between normal
operation state and error code. These errors do not require resetting. To remove
the error the defective part or component must be repaired.
These errors do not stop the controller from functioning, although the service
may be impaired in some circumstances.
5.5.3(h) Appliance type mode
The appliance type/code selection menu (A10, A20, A30) is hidden. It is only possible
to get to the appliance selection using the rest button (B1) on the main board. When
going from the show ‘locking error’ to show ‘blocking error’ menu do not release the
button but hold it for 10 seconds. The display will change from ‘c’ to ‘A’. At this stage
the appliance type can be selected.
All models have a unique ID tag as part of the appliance wiring harness (see section
5.1). The controller reads this tag and compares it with the model selected on the
controller and the procedure for setting the appliance code in the controller is
described below.
• The appliance selection menu (A0 ... A9, A10 ... A30) on the controller is hidden. It
is only possible to get to the appliance selection using the reset button (Left hand,
B1) on the main board.
• When going from the show ‘locking error’ to show ‘blocking error’ menu (see figure
5.3), do not release the button but hold it for 10 seconds. The display will change from
‘c’ to ‘A’. At this stage the push button (B1) can be released.
• The appliance type can now be selected by using right hand push button, B2, e.g.
A03.
• Press the reset button, B1, to accept the
setting.
• If the selected appliance code does not match
with the ID Resistor fitted to the appliance, then,
an error ‘33’ will be displayed.
5.5.3(i) Error codes and handling
Errors are divided into two categories with two
groups each. The categories are;
• Main errors for the main control including the
burner and CH errors
• DHW errors for the DHW state machine
The first category is divided into two groups.
One group of locking errors and one group of
blocking errors.
A main locking error can only be reset by
pressing the reset button. If the appliance
power supply is interrupted the appliance will
return to the main locking state it was in before
the interruption occurred. Locking errors are
used to indicate severe errors that can cause a
safety critical situation.
Less critical errors are indicated as blocking
errors. These errors can sometimes be resolved
without user intervention. Once the cause for
the blocking error disappears the appliance
resumes with normal operation.
If no error (locking or blocking) is detected
the internal error number is set to 255 and the
digital point of the left display digit flashes. If
any error is detected the fault number is set to
the corresponding internal error number, the
digital point of the right display digit flashes and
if necessary the burner is stopped. If more than
one error conditions occurs at the same time the
error with the highest priority overrules the error
with a lower priority. The lower the internal error
number, the higher the priority of an error.
5.6 INITIAL LIGHTING
(a) Check that the electricity supply is ISOLATED
and basic electricity supply checks listed in
section 5.2 have been carried out.
(b) Ensure that the boiler and system are full of
water and the system is thoroughly vented.
For sealed systems ensure that the system
is charged to 1.0 bar nominal pressure.
(c) Turn on the gas supply and open the
gas service cock to purge the gas line in
accordance with the current issue of BS
6891. After purging procedure check for gas
leaks and rectify any faults.
