FUNCTIONS PROTECTED BY CODE
(CODE).
They are advanced character settings (reserved for an ena-
bled technician), a four character code must be entered in
order to access them (code: 1122).
Press the

After which it is possible to display and modify the follow-
ing functions.
10.1
AMB (room probe - On / Off or Modulating
functioning mode).
Allows to activate or deactivate the room probe present in
CRONO 7. On the basis of the parameter setting, it will be
possible to regulate the following options:
- AMB: ON (standard value); it is possible to select a cor-
rection factor of the room probe reading and change the
modulating function.
- AMB CR: room probe reading correction, the room probe
range reading can be corrected within a range of +
3.0 - 3.0°C.
- MODUL (On / Off or Modulating functioning):
allows to set functioning of the CRONO 7 On/Off
or Modulating. Set at ON the Modulating function is

activated, which guarantees greater control precision
of the room temperature and therefore improved
comfort. Boiler activation will depend on the room
temperature but also on the heat inertia of the system
(set via the "DIMENS" parameter). As a consequence
there will be boiler on/off cycles in which the switch-
on cycle is longer, the lower the room temperature,
with respect to that set. Set at OFF, the Modulating
function is deactivated. The request will be satisfied
only depending on the room temperature.
- AMB: OFF, the system will not function, regulating the
room temperature but only depending on the time pro-
gram set.
10.2
ANTIGL (anti-freeze level).
Allows to set the room temperature for activation of the
anti-freeze function. Can be regulated from 0°C to 10°C
and is set at 5°C as standard.
10.3
MANUTZ (programmed maintenance).
Sets the interval for periodic maintenance (can be set from
6 to 24 months or "Off "). When the period has been set,
the telephone number that the user must contact to perform
periodic maintenance is set.
