18 Error indication
When detected, errors are indicated on the display. Some, of a temporary nature, will not usually result in the boiler
locking out. Whilst the control system will try its utmost to prevent lockout, and may temporarily switch off the unit,
any fault which could potentially damage the appliance will result in lockout. The following are examples of mes-
sage display, which fall into two categories - i.e. Blocks and Errors.
Blocks with a number in the last 2 positions.
Block 01:
External safety contact cut out
Block 11:
Maximum
'
T of flow and return sensor in central heating has repeatedly been exceeded. During the
block normal operation of the hot water supply is possible. The pump continues to operate at minimum
capacity during the block.
Block 12:
Maximum
'
T of flow and return sensor in domestic hot water has repeatedly been exceeded. During
the block normal operation of the central heating installation is possible. During the block the pump
continues to operate at minimum capacity.
Block 60:
Incorrect parameter setting of the minimum or maximum power.
Block 67:
A
'
T has been detected between flow and return sensor whereas the burner is not in operation. After
the
'
T has disappeared the block will disappear.
Block 80:
Maximum flue gas temperature has been exceeded (if present). The block will not be cancelled until
the flue gas temperature has arrived below the temperature.
Block 81:
The flue gas sensor is not connected although it has been connected to the control. The burner is
blocked until the flue gas sensor is reconnected.
Block 82:
The flue gas sensor has short-circuited, heat requirement blocked and pump capacity at minimum.
Block 85:
The control has not detected a water flow. The venting cycle is started. If during this cycle water flow
is detected, the venting cycle is ended and the burner is released.
