Electrical Connections
The pumps and others external compo-
nents have to be installed using an adequate re-
lay/commutator, as shown in Figure 12.
To connect the terminal strip to the relay (to be
housed in a separate external cabinet ) use ca-
ble type H05 VV-F with minimum outside di-
ameter 6mm and suitable conductor section,
taking care to fix the same in the cable clamps.
For example, how connecting the pump of low
temperature to a timer and / or outside the
room thermostat circuit is shown in Figure 14.
By this system is possible to power on circula-
tors (external devices) directly from the net-
work with no electrical load passing through
the fuse of the board. Moreover, in case of
emergency mode, the manual device 0, 1, AUTO
controls the operation of the pump regardless
of what the board. For these reasons it must
explicitly provide for the use.
Cable of the same type of power cable is to be
used (unless otherwise specified by the manu-
facturer of the component)
6.2.5 Room thermostat connection
(on/off)
Connect the high temperature system's envi-
ronment thermostat to terminals no. 9 and 10
(Figure 13).
The low temperature system's thermostat shall
be connected to terminals no. 11 e 12 (Figure
13).
6.2.6 Outside temperature probe
connection
If outside temperature regulation is to be used,
the outside probe (optional) needs to be con-
nected to terminals no. 7 and 8 (Figure 13).
The outside probe shall be installed on an outer
wall, North or North/East, at a minimum height
of 2.5 metres, away from windows, door, and
ventilation grids. Never install the probe in a
position exposed to the sun.
If it is necessary to modify the climatic curve
set, please contact a Technical Assistance Cen-
tre.
