Use the ambient thermostat's clamps indi-
cated in Fig. 6.15 and Fig. 6.16. to connect
the zone valve Insert the electric cables of
the zone valve's micro switch contacts in
clamps "1 and 3" of the ambient thermo-
stat's terminal block as in Fig. 6.16.
Remove the electric jumper between "1
and 3".
Be careful not to connect pow-
ered cables on clamps "1 and
3".

Connection of a remote controlled zone
valve
Connecting a zone valve to the terminal of
the auxiliary card and the remote control to
the specific terminals it is possible to control
this zone with the same remote control.
Moreover, should another zone controlled
by an ambient thermostat be present it is
possible to regulate both zones with a dif-
ferent delivery temperature.
In order to achieve this setting it is neces-
sary to enter into the programming (load en-
try sequence), scroll the various parameters
using keys 17 or 18 (Fig. 6.23) until the let-
ters P04 appear on the LCD display as well
as the value of the parameter, indicating the
entry in "parameter 04" (Fig. 6.22).
Fig. 6.22
Utilising keys 11 or 12 modify the value of
the parameter from 00 to 01 valid in order
to differentiate the delivery temperatures of
the heating system.
By pressing key 14 confirmation of the in-
serted value is obtained.
Press keys 17 or 18 to exit without changing
the value.
