ELECTRICAL CONNECTIONS
All the boiler’s internal electrical connections have been
pre-wired and tested in the factory.
Only the following connections are needed for installation:
- Connect the boiler to the mains power supply (single
phase 230V-50Hz);
- The room thermostats (TA Dir and TA Mix1) or remote
controls (REC 07/08 Zone Dir and REC 07/08 Zone Mix);
- outdoor temperature sensor (SE).
POWER SUPPLY
Connect the boiler to the mains power supply using the
cable (1) at the rear of the appliance.
ROOM THERMOSTATS OR REMOTE CONTROLS
- Remove the top front panel by pulling it outwards
- Remove the cover (2) from the CH circuit (BAG) control
unit to access the card inside
- Connect the room thermostats (TA) or remote controls
(REC 07/08) as shown in the figure alongside.

It is recommended to install AT LEAST ONE
REMOTE CONTROL (REC 07/08), available as an
accessory, to control the first mixed CH zone.
This allows you to control settings for the other
zones too.
