DELTA T ON PUMP
The parameter allows you to manage the temperature difference between
the collector probe and the lower storage cylinder probe for the thermal load
of the storage cylinder (activation of the solar pump).
The factory setting is 8°C.
The parameter can be set with the range 4°C - 30°C.
DELTA T OFF PUMP
The parameter allows you to manage the temperature difference between
the collector probe and the lower storage cylinder probe for the interruption
of the thermal load of the storage cylinder (deactivation of the solar pump).
The factory setting is 4°C.
The parameter can be set with the range 4°C - 30°C.
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
The factory setting is 110°C.
The parameter can be set with the range 80°C - 180°C.
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.
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.
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.
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 storage cylinder cooling function; there
are two options available:
SOLAR PUMP MODE
three options available:
according to the solar management rules
Setting the thermoregulation
access the technical parameters menu, as indicated in the paragraph
"3.21 Access to the parameters"
Thermoregulation only works with the outdoor temperature sensor
connected and active only for the HEATING function;
The temperature measured by the outdoor temperature sensor is displayed
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).
There are 2 parameters that compete to calculate the output setpoint:
slope of the compensation curve (KT)
offset on the reference ambient temperature.
Selecting the compensation curve (parameter OTD CURVES
The compensation curve for heating maintains a theoretical temperature of
20°C indoors, when the outdoor temperature is between +20°C and -20°C.
The choice of the curve depends on the minimum outdoor temperature
envisaged (and therefore on the geographical location), and on the delivery
temperature envisaged (and therefore on the type of system). It is carefully
calculated by the installer on the basis of the following formula:
T. outlet envisaged - Tshift
20- min. design external T
If the calculation produces an intermediate value between two curves, you
are advised to choose the compensation curve nearest the value obtained.
if the value obtained from the calculation is 1.3, this is between
Example:
curve 1 and curve 1.5. Choose the nearest curve, i.e. 1.5.
The settable KT values are as follows:
Standard system: 1.0-3.0
Through the interface it is possible to access the menu CH and the parameter
to set the pre-selected thermoregulation curve:
