• Opening the contact the thermostat will return to the state set previously.
If the thermostat is off (operation status
OFF
):
• When the contact is closed the thermostat remains off (
OFF
) (symbol
on);
• Keeping the contact closed it is still possible to position the thermostat to
reduced capacity ( ) acting on the button
;
• Opening the contact the thermostat will return to the state set previously.
4.3 Remote control Entry (terminal
)
The entry allows activating the thermoregulation in a stable mode or with timer, by
using an external contact. It is generally useful to switch on the thermostat using
remote controls (e.g. telephone controllers etc.).
The NA external contact must be connected to the phase (terminal L) – (see para-
graph 3.2.3).
4.3.1 Stable activation
If the thermostat is off (Operation status
OFF
):
• When the contact is closed, after about 5 seconds the thermostat switches on
( ) (symbol
on);
• Keeping the contact closed it is not possible to switch off (
OFF
) the
thermostat;
• Opening the contact, the thermostat switches off (
OFF
).
If the thermostat is on (Operation status ):
• when the contact is closed, after about 5 seconds the thermostat remains on
( ) (symbol
on);
• keeping the contact closed it is not possible to switch off (
OFF
) the
thermostat;
• opening the contact, the thermostat switches off (
OFF
).
If the thermostat is in reduced capacity (operation status ) (symbol
on):
• when the contact is closed, after about 5 seconds the thermostat goes to
operation status (symbol
on) except where the reduction capacity
is determined by the entry
; in this case this status will be maintained
(symbol
and
on);
• opening the contact the thermostat switches off (
OFF
).
N
No
otte
e::
should the
reduction capacity be determined by the entry
, the thermostat will keep the
reduced capacity (symbol
and
OFF
on).
4.3.2 Activation with timer
If the thermostat is off (Operation status
OFF
):
• when the contact is closed for a time going from 1 to 5 seconds the thermostat
will switch on ( ) with timer (symbol on). The thermostat will be active
for the set amount of time (see paragraph 5.7), after this time it will switch off
(
OFF
).
If the thermostat is on (Operation status ):
• when the contact is closed for a time going from 1 to 5 seconds the thermo-
stat will switch on ( ) with timer (symbol on). The thermostat will be
active for the set amount of time (see paragraph 5.7), after this time it will
switch off (
OFF
).
If the thermostat is in reduced capacity (operation status ) (symbol
on):
• When the contact is closed for a time going from 1 to 5 seconds the thermo-
stat will go to with timer (symbol on). The thermostat will be active
for the set amount of time (see paragraph 5.7), after this time it will switch off
(
OFF
).
Nota:
should the reduction capacity be determined by entry
, closing the contact
for a time going from 1 to 5 seconds, the thermostat will go to reduced capacity sta-
tus with timer (with symbols and
on). When the set time is up (see paragraph
5.7), if entry
is still closed the thermostat remains in the reduced capacity mode
(symbol
on).
