10.2.2 CONNECTING AN EXTERNAL STORAGE BOILER (for heating only models)
The water heaters combined with the boilers are those envisaged by the manufacturer.
The DHW priority sensor NTC and the motor of the 3-way valve are not included in the kit of the appliance because they are
supplied as accessories.
CONNECTING THE STORAGE BOILER SENSOR
The boiler can be electrically connected to an external storage boiler. A diagram of the hydraulic connection of the external storage
boiler is shown in annex "SECTION" F. Connect the priority sensor NTC to terminals
element of the NTC sensor must be inserted in the special well located on the storage boiler. Make sure that the exchange capacity
of the storage boiler coil is appropriate for the power of the boiler. Adjust DHW temperature (+35°C...+60°C) by pressing
IMPORTANT: set parameter F03 = 003 as described in the SETTING PARAMETERS section.
