To set the sanitary water temperature, see
the paragraph "TO SET HEATING AND
SANITARY WATER TEMPERATURE FROM
THE REMOTE CONTROL PANEL".
HOLIDAY
Plant surveillance is active and services
(heating/sanitary water/zone manage-
ment) are deactivated. On expiry of the
count expressed in days (max. 99), "AUTO-
MATIC" mode will take over again with the
selected programme. The environment
antifreeze function is always active, howe-
ver, and will switch on the boiler when the
environment temperature falls below the
level (min).
CHIMNEY SWEEP
To check boiler combustion, press the (S)
and (FILL) keys at the same time.
The test can also be carried out with the
boiler working in D.H.W. mode. Therefore,
after having activated the chimney sweep
function, withdraw hot water from one or
more cocks. In this condition the boiler
functions at maximum output with dome-
stic hot water temperatures between 60
and 70°C. During the test, the hot water
faucets must remain open. When combu-
stion has been checked, close the with-
drawal cocks so that the boiler can return
to the previous functioning mode. The
chimney sweep function will automatically
switch off after 15 minutes.
NOTE: The flashing "S" symbol appears on
the remote control during the functioning
period.
