ZONE1 OTR
This parameter allows you to activate thermoregulation mode for zone 1 when the system
has an outdoor temperature sensor connected. The factory setting is 0, the boiler always
operates for zone 1 at a fixed point; to have the boiler work in climate mode connect an outdoor
temperature sensor and set the parameter to 1, connect an outdoor temperature sensor. With
an outdoor temperature probe disconnected the boiler always operates at a fixed point.
See paragraph "4.5 Setting the thermoregulation" for more details about this function.
ZONE1 OTD CURVES
This parameter allows you to set the number of the compensation curve for zone 1 used by the
boiler when in climatic mode. The factory setting for this parameter is 2.0 for high temperature
systems and 0.5 for low temperature ones. The parameter can be set with the range 1.0 - 3.0
for high temperature systems, 0.2 - 0.8 for low temperature ones.
See paragraph "4.5 Setting the thermoregulation" for more details about this function.
ZONE1 NIGHT COMP
This parameter allows you to activate "night compensation" for zone 1.
The default value is 0, set to 1 to activate the function.
See paragraph "4.5 Setting the thermoregulation" for more details about this function.
DHW
ANTILEGIO
This parameter allows you to activate the "antilegionella" function when the boiler is connected
to a water tank with a probe (Case C).
The factory setting of this parameter is 0 (function disabled).
Set the value to 1 to activate the weekly antilegionella function, the is carried out the third day
of the week at 03:00 am.
Set the value to 2 to activate the daily antilegionella function, the is carried out every day of
the week at 03:00 am.
See paragraph "4.15 Anti-legionella function (only if connected to a water tank with probe)" for
more information about this function.
ANTILEGIO TIME
This parameter allows you to set the time the "antilegionella" function is carried out when the
boiler is connected to a water tank with a probe (Case C).
The factory setting for this parameter is 03:00 am.
ANTILEGIO OUTLET TANK FLOW
This parameter allows you to set the delivery value to the water tank when an antilegionella
function is in progress.
The factory setting for this parameter is 80°C and it can be set in the 65°C - 85°C range.
TANK FLOW TEMP
This parameter allows you to change the delivery temperature to the water tank for a domestic
hot water request.
The factory setting for this parameter is 80°C and it can be set in the 50°C - 85°C range.
SLIDING OUTLET TANK FLOW TEMP
This parameter allows you to activate the SLIDING OUTLET function to modify the delivery
setpoint used by the boiler, when there is a domestic hot water request (only when a water
tank with a probe is connected, Case C). The factory setting for this parameter is 0 (function
deactivated), set the parameter to 1 to activate the function.
See paragraph "4.14 Sliding delivery (only if water tank connected)" for more information about
this function.

SOLAR
FSUN
This parameter is used to enable the management of the solar water tank, the BE15 accessory
board must be used.
The factory setting is 0 = solar water tank management disabled, set the parameter to 1 to
enable the function.
T MAX TANK
The parameter allows you to set the maximum temperature of the top part of the water tank.
The factory setting is 60°C.
The parameter can be set with the range 10°C - 130°C.
DELTA T ON PUMP
The parameter allows you to manage the temperature difference between the collector probe
and the lower water tank probe for the thermal load of the water tank (activation of the solar
pump).
The factory setting is 8°C.
The parameter can be set with the range 4°C - 30°C.
Note: the DELTA T ON PUMP value should be higher than DELTA T OFF PUMP.
DELTA T OFF PUMP
The parameter allows you to manage the temperature difference between the collector probe
and the lower water tank probe for the interruption of the thermal load of the water tank (deac-
tivation of the solar pump). The factory setting is 4°C.
The parameter can be set with the range 4°C - 30°C.
Note: the DELTA T OFF PUMP value should be lower than DELTA T ON PUMP.
INTEGRATION DELAY
The parameter allows you to set the delay time of the solar integration by the boiler. The factory
setting is 0 min. The parameter can be set with the range 0min - 180min.
COLLECTOR T MIN
With this parameter you set the minimum temperature of the collector for activating the solar
collector anti-freeze function. The factory setting is: - - °C (solar collector anti-freeze disabled).
The parameter can be set with the range -30°C - +5°C.
COLLECTOR T MAX
Parameter for setting the maximum temperature of the collector for the solar collector pump
lockout (system protection). The pump is then enabled as soon as the temperature of the
collector falls below [COLLECTOR T MAX - 10°C]. The factory setting is 110°C.
The parameter can be set with the range 80°C - 180°C.
Note: the COLLECTOR T MAX value should be higher than COLLECTOR T PROT.
COLLECTOR T PROT
Parameter for setting the maximum temperature of the collector for activating the solar collector
cooling function. The factory setting is 110°C.
The parameter can be set with the range 80°C - 180°C.
Note: the COLLECTOR T PROT value should be lower than COLLECTOR T MAX.
COLLECTOR T AUTH
Parameter for setting the minimum temperature for enabling the solar collector pump.
The factory setting is 40°C. The parameter can be set with the range -20°C - +95°C.
Note: the COLLECTOR T AUTH value should be higher than COLLECTOR T LOCK.
COLLECTOR T LOCK
This parameter allows you to set the minimum temperature for disabling the solar collector
pump. The factory setting is 35°C. The parameter can be set with the range -20°C - +95°C.
Note: the COLLECTOR T LOCK value should be less than COLLECTOR T AUTH.
PWM COLL PUMP
This parameter allows you to set the PWM modulation period of the solar pump.
The factory setting is 0min (solar collection pump modulation function disabled). The parameter
can be set with the range 0min - 30min.
TANK COOLING
Parameter for enabling/disabling the water tank cooling function; there are two options avail-
able:
0= FUNCTION NOT ACTIVE (factory setting)
1= FUNCTION ACTIVE
SOLAR PUMP MODE
Parameter for configuring the operation of the solar collector pump; there are three options
available:
0= OFF (factory setting) ==> the solar collector pump is always off
1= ON ==> the solar collector pump is always on
2= AUTO ==> the solar collector pump switches on and switches off according to the solar
management rules.
4.5 Setting the thermoregulation
Enabling THERMOREGULATION occurs in the following way:
ƒ access the technical parameters menu, as indicated in the paragraph "3.19 Access to
the parameters"
ƒ select the menu CH and then OTR=1.
Thermoregulation only works with the outdoor temperature sensor connected and active only
for the HEATING function. If OTR = 0 or outdoor temperature probe disconnected the boiler
operates at a fixed point. The temperature measured by the outdoor temperature sensor
is displayed in "4.21 INFO menu" under OUTDOOR TEMP SENS. The thermoregulation
algorithm will not directly use the outdoor temperature, but rather a calculated outdoor
temperature that takes into account the building's insulation: in buildings that are well
insulated, the outdoor temperature variations will have less impact than those that are poorly
insulated by comparison.
REQUEST FROM OT CHRONOTHERMOSTAT
In this case the delivery setpoint is calculated by the chronothermostat according to the
outdoor temperature value and the difference between the ambient temperature and the
desired ambient temperature.
REQUEST FROM ROOM THERMOSTAT
In this case the delivery setpoint is calculated by the adjustment board according to the
outdoor temperature value so as to obtain an estimated outdoor temperature of 20°
(reference ambient temperature).
