6 .2 .2 Connection to thermoregulators
heating units are equipped with an
Power Plus Box 1001
extremely versatile control and operating system, able to
operate three independent systems functioning at different
temperatures. The procedure for connecting up the output
signal to the specific points on the terminal board will be
illustrated in the following pages (see Figure 15).
H05-VV-F type cables with minimum external diameter of
5mm and adequate conductor section may be used for
thermoregulation and low voltage systems, being careful to
fix the latter to their cable guides.
6 .2 .3 Connection to pumps
The Power Plus Box 1001 adjustment system operates three
circulators at the same time for distribution to the high and
low temperature and hot water systems.
This operation is done by a Technical Assistance Centre
authorized by
during commissioning the system, by
B
setting an appropriate parameter (specifically n. 34 in the
list of parameters).

Pumps or other external parts will be installed by using
a special relay/change-over switch as demonstrated
in Figure 14.
Use a H05-VV-F type cable with minimum external diameter
of 6 mm and adequate conductor section to connect the
terminal board to the relay (to be housed in a special
external board), being careful to fix the latter to its cable
guide.
For example, by connecting the low temperature circulator
to a timer and/or external room thermostat the electrical
installation will be the one shown in Figure 14.
This device will enable the circulators (external devices)
to be powered directly from the mains, without the relative
electrical load passing through the fuse on the board.
Furthermore, in cases of emergency mode, circulator
functioning can be controlled by the 0, 1, AUTO manual
device independently from the one on the board. It must
be strictly used for the above reasons.
Use a bi-polar cable of the power cable sort (unless
otherwise recommended by the component's manufacturer.
6 .2 .4 Connection to room thermostats (on/
off)
Connect up the high temperature system room thermostat
to terminals 9. and 10 (Figure 15).
The thermostat for the low temperature system must instead
be connected to terminals n. 11 and 12 (6585977f-8ecf-
4eeb-8acd-1be6cdc82fb2).
6 .2 .5 Connection to weather temperature
probe
If you want to use a weather thermoregulator, the external
probe (optional) must be connected up to terminals n.7
and 8 (Figure 15). The external probe must be placed on
an outer wall facing north to north-east at a height of at least
2.5 metres and at a distance from windows, doors and air
vents.
Protect the probe from direct exposure to the sun. Contact
the Technical Assistance Centre authorized by
