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 CH mode only
and alarm will NOT be displayed.

The DHW may be reactivated for 24 hours
by disconnecting and reconnecting the
power supply to the boiler.
Check that the connector supplied in
the AD 212 kit (DHW Sensor), which
has a 22k Ohm resistance and a
100nF capacitor fitted, is correctly
connected to terminals 25 and 26.

To Shut Down the Boiler
1. For short periods
Set the boiler on/off switch (1) to OFF.
2. For longer periods
Set the boiler on/off switch (1) to OFF, wait 10 minutes then
switch the electricity supply to OFF. For longer periods the
entire system should be drained, including the domestic
hot water supply.
To Relight the Boiler
Refill the system if it has been drained, taking care to ensure
no air is in the boiler or system.
Repeat the procedure detailed in 'To light the boiler'.
Frost Protection
If frost is likely, leave the boiler thermostat at a reduced
temperature setting. Ensure external controls allow the boiler
to operate if necessary. Note that this may not protect remote
parts of the system, in which case a separate frost thermostat
should be fitted or the system drained and the boiler shut
down, as for Long Periods.
Boiler Overheat Thermostat
Boiler overheating is detected by the overheat thermostat
connected to the boiler control module. If the boiler overheats, it
will shut down the burner but the circulating pump will continue
to run. The display may show until the water cools.
Press the safety thermostat reset button, under the screw top
cap (4), and the burner will relight. If the fault recurs, turn off the
boiler and consult a recognised installer (CORGI registered for
gas-fired boilers.)
Escape of Gas
Should a gas leak or fault be suspected contact your local gas
supplier without delay.
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains use a damp cloth and
mild detergent.
DO NOT use abrasive cleaning materials.
