Activation of the disinfection function can be performed by con-
necting a timer to the inlet that has a default value set for 2 a.m.
the night between Sunday and Monday; as statistically this is a
time with a low probability of employment on behalf of the us-
ers.
The duration of the action is determined by the characteristics
of the system. Legionella bacteria react differently depending
upon the maximum temperature reached within the circuit and,
with the increase of temperature, the duration time decreases.
The default parameters set in the device are:
temperature setting > 60°C for a duration of 2 hours but other
settings are also possible taking into consideration the following
rules:
– above 70°C disinfection lasts 30 minutes
– between 65° and 70°C disinfection lasts 60 minutes
– between 60° and 65°C disinfection lasts 120 minutes
– between 57.5° and 60°C disinfection lasts 180 minutes
– between 55°C and 57.5°C disinfection lasts 240 minutes
The regulator indicates that the anti-Legionella function is active
through the flashing of the LED , it checks actual execution of
the action on the basis of the preset parameters and then even-
tually exits the function after a timeout of 5 hours.
During the anti-Legionella function the cooling and heating re-
quirements of the system are not satisfied.
It is advisable to introduce a safety device to prevent burns on
every system in order to avoid getting burnt when hot water is
taken during the thermal disinfection phase.
Terminals 5-6: Connection used to select the TA “hot water
only”, mode from a clean remote contact. It in-
hibits the operation of the cooling and heating
modes, leaving the production of hot water as
the only active mode.
230 V output voltage.
The P2 secondary connection pump is connected directly to
this input and also operates with the regulator in standby
mode.
Terminals 7-8: Contact used to select ON/OFF from a poten-
tial-free remote contact. This puts the device
in standby, deactivating all the settings and is
shown on the display by OFF. While in standby,
the device runs an antifreeze cycle based on the
ALO threshold and on the readings of sensors T2
and T3; operation is signalled on the display by
the alternating OFF and ALO signs. This may be
set by means of parameter dI4 to enable/disable
the hot water function (in this case, the standby
condition shown on the display only occurs if in-
put TA is open at the same time).
Terminals 9-10 : potential-free contact (closed for hot water)
to allow back-up hot water (max. 2A).
Terminals 13-14 : External air temperature detection sensor
input. The sensor should be positioned so that
it detects the real outside air temperature and
must not be influenced by factors which may dis-
tort the reading (e.g. direct sunlight, other heat
sources, accumulations of snow/ice). Electrical
connections to be established by the installer
(max. distance 50 m).
Terminals 15-16 : potential-free contact (normally open for
back-up boiler - max. 2 A).
Terminals 17-18 : 230 V power (max. 1 A) for connecting ther-
mostat and resistor included in the HEATED CON-
DENSATION COLLECTION BOWL KIT LB0656.
Terminals 19-20 230 V input for P3 high temperature circula-
tion optionally in the device.
