[EN] - CONNECTING THE AMBIENT THERMOSTAT AND/OR TIME CLOCK
HIGH VOLTAGE CONNECTIONS (fig. a, b, c)
The ambient thermostat and heating time clock contacts must be suitable
for V= 230 Volt.
Make the connections for the environmental 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= 2AF fuse
2= ambient thermostat
WATER TANK SENSOR CONNECTIONS (¿ g. d)
Make the connections for the water tank sensor to the terminal board M4 as
indicated in the diagram.
3= water tank sensor
LOW VOLTAGE CONNECTIONS (¿ g. e)
Make the connections for the low voltage functions to the 10-pole low voltage
connections terminal board (M10), as indicated in the diagram.
4= low temperature thermostat
5= external sensor
LOW VOLTAGE CONNECTIONS (¿ g. f)
Make the connections for the low voltage functions to the 10-pole low voltage
connections terminal board (M10), as indicated in the diagram.
Fit the P.O.S. (DHW time clock) as shown in the diagram after removing the
jumper on the 10-pin terminal board (M10).

SPECIAL SYSTEMS (¿ g. 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.
