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 calorifier is
empty or incorrectly
fitted AD212 kit
connector

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.
