The room thermostat and heating time
clock contacts must be suitable for V=
230 Volt.
Make the connections for the room thermostat
and or the time clock on the high voltage
connections terminal board with 6 poles (M6)
according to the following charts, after having
removed the Ubolt from the terminal board.
1= 3.15AF fuse
2= room thermostat

SPECIAL SYSTEMS (fig. g)
Connect the pump to the 2-pole terminal board,
in the area dimensioned for V = 230 Volts. The
boiler is capable of managing a supplementary
pump, connected hydraulically as shown in the
following diagram. In this way, it is possible
to manage systems with flow rates in excess
of 1300 l/h. The supplementary pump is not
supplied as standard equipment, but must be
chosen carefully by the installer on the basis
of the dimensions of the systems. To activate
the pump, set parameter 20, heating mode, on
position 03, supplementary pump (refer to the
chapter "Setting parameters" for further details).
7= boiler
8= boiler pump
9= supplementary pump
10= hydraulic separator
- Close the protective caps on the terminal
board, making them slide inwards, and put
the previously removed screws back in
- Close the instrument panel, reassemble the
coverings and boiler shell.
