4 DISABLING THE BOILER
LT.AL.W7H.000.217 + LT.AL.W7H.000.218
The boiler must be disabled before any maintenance or repairs are carried out. If the
central heating system is not used for a long time (during the holidays, for instance,
or periods of milder weather) it is advisable to disable the boiler.
1. Disable boiler with frost protection, during longer periods of non-use
• Set the room thermostat or other controls to a low temperature, e.g. 10°C,
• Switch setting p4 to 1 (Eco mode), this will switch off the heat retention function.
Now the boiler will only start working to protect itself against freezing.
With an external frost protection connected, the boiler can also prevent the central
heating system from freezing.
