This is a gas condensing appliance intended to generate
centralised heating. It can also be used for domestic hot
water production for civil use, but it must be appropriately

prohibited.
Maximum domestic hot water service output heat is always
guaranteed as the appliance give priority to said service.
Follow the procedure described in section 16.6 to adjust the
domestic hot water temperature.
The heating system can be created with heat elements that
work at a temperature range from 30°C to 80°C.
The boiler can be connected to a room thermostat, an
external temperature sensor or a 0-10Vdc analogue input.
This boiler must be connected to a heating and domestic
hot water production system with required output heat that
is compatible with the features of the appliance itself.
