DESCRIPTION
First of all we would like to thank you for your purchase and we hope that the Allegro 576 meets the needs of
your installation.
The Allegro 576 is a thermal solar energy regulator with six 5A 250V~ relay outputs and seven PT1000 probe
inputs (three 1.5 metre probes are included, each with a range of -50 ºC to +200 ºC), in addition to a pulse input.
The relays are potential-free contacts, which means that they only act as switches and the devices connected to
the relay need to be powered.
When programming the Allegro 576 you will find different predefined installation systems that will help you to
quickly and easily configure your installation. Depending on the system you have chosen, you may activate
additional functions, such as unit heater, independent thermostat, return increase, double pump, anti-frost,
calorimeter and tubular sensors, provided that the resources (relays) required for the functions are not being
used by the system chosen to configure your installation.

Operation of the priorities
When an accumulator is below its priority temperature, it is charged
exclusively until it reaches the temperature. If another accumulator
falls below its priority temperature while the former is charging, both
become priority and are both charged at once until one of them
reaches its minimum temperature.
In winter
If the temperatures of AC1 and AC2 are below 65 and 40,
the installation heats them both at once. When AC2
reaches 40, only AC1 is heated until it reaches 65. Once it
reaches this temperature there are no other accumulators
in priority mode and it heats all three accumulators until
they reach 70, 45 and 35, respectively.
If one of them falls below its priority temperature, its priority
is activated again and only the one below its priority value
is heated.
In the case of excess heat: When AC1 has reached 70 and
AC has reached 45, the swimming pool is heated to
dissipate the excess heat instead of accumulating it in the
collectors, thus preventing the installation from
overheating.

Since the underfloor heating does not need to be activated
during the summer, its priority can be set to 5 ºC and its
alarm to 5 ºC to deactivate it, and AC3 can be set to 5 ºC
with its alarm to 35 ºC so it is not priority. The system then
heats AC1 until it reaches 65 ºC, and once it reaches this
temperature it heats AC1 and AC3 at the same time until
they reach their alarm temperature, at which point the
system stops charging the accumulators.

SETTINGS
Sequential priority OFF
When accumulator number 1 is below its priority temperature, it is
charged exclusively until it reaches its priority temperature. If
number 2 falls below its priority temperature while number 1 is
charging, it cannot be charged until accumulator 1 reaches its
minimum temperature (priority temperature).
Sequential priority ON
Example of operation
Sequential priority OFF
Sequential priority ON
If the temperatures of AC1 and AC2 are below 65 and 40,
the installation only heats AC1 (numerical order) until it
reaches 65 ºC. Once it has reached this temperature it is
no longer priority and the system then exclusively heats
accumulator 2 until it reaches 40. As there are no other
priority accumulators, the two accumulators are heated at
once until their temperature alarms are triggered.
Since the underfloor heating does not need to be activated
during the summer, its priority can be set to 5 ºC and its
alarm to 5 ºC to deactivate it, and AC3 can be set to 28 ºC
with its alarm to 35 ºC. The system then heats AC1 until it
reaches 65 ºC, and once it reaches this temperature it
heats AC3 until it reaches 28 ºC, then it charges AC1 and
AC3 at the same time. If AC1 falls below 65 ºC while AC3 is
charging, the system stops charging AC3 so it can charge
AC1 until it reaches 65 ºC.

MENU
When a system uses several accumulators (tanks, heating, swimming pools, etc.) it can set a priority for charging them
(accumulator priority setting on page 28). Their minimum temperature is configured and these temperatures are classified as
priority and non-priority when charging. The tanks with the lower temperatures are given priority until they reach the
temperature when they become non-priority.
When the sequential priority parameter is activated, it assigns the charge order in accordance with the numerical order and the
temperatures. The numerical order assigned to the accumulators is the numerical order of the relays.

MENU

GETTING STARTED
- If you wish to activate one of the functions, first
make sure you know what resources the function
needs, the type (fixed, exclusive or shared) and
check that the configured system leaves the
required resources available:
- Seven PT1000 probes (S1, S2, ..., S7)
- Six 5A 250 V~ relays (R1, R2,..., R6)
- 1 pulse input (Calorimeter).
These resources are shared by systems and
functions in different ways.
The probes and relays in the systems are pre-
assigned and non-configurable. The probes can be
shared by the systems and the functions
The relays cannot be shared between systems and
functions (except the OR and AND functions).
The screen only shows the available systems, relays
and probes, depending on the activated functions and
systems.
If you need a function or system which is not shown,
you will have to free the required resources first.
The Allegro 576 is a thermal solar regulator.
On the screen you can see diagrams showing all the
information required to quickly and easily configure
and adjust your installation.
In normal operation mode, the screen shows the
status of the devices (pumps, relays, alarms, etc.)
and the probe temperatures.
For optimal operation carefully read this section,
which indicates the steps to follow to adapt the
Allegro 576 to your installation.
Steps to follow:
- Once installed and once the connections have
been made, you can connect the Allegro 576 to the
mains.
- Before configuring the system values and settings
it is advisable to test the probes and relays to
check the correct operation of the installation.
(This step is explained on page 9.)
- Once you have verified the operation, choose the
system that best suits your installation type from
among the available configurations (pages 22 and
23). Remember that System 1 has 6 variants
depending on the number of accumulators to be
configured, although only 1 symbol is shown on
the screen.
- All the settings are preset to factory default values.
If these values do not suit the needs of your
installation, consult page 26 to configure them.

PROBES
- It is advisable only to use original probes (1.5m
PT1000). Should they need to be extended, they
must be welded together avoid losing the reading
value and the joint must be shrink wrapped to
insulate against humidity.
- The probes of the panels must be installed at the
output leading to the installation.
- The accumulator probes must be installed inside the
accumulator.
- Under no circumstances should the probe cables be
laid in the same channel as the electrical cables.
RELAYS
- The relays that activate the devices of your
installation supply a voltage of 230 V~ and a
maximum current of 5(3) A (max. charge of 10A from
the three relays) so there is no need to
independently power valves, pumps, etc.
- Ensure that electrical connections from the devices
to the contacts of the relays have been made
correctly before connecting the Allegro 576
terminal to the mains .

OPERATION
- To access the system menu press OK (with the
display on) and use the arrows to move to
SYSTEMAS.
- Press OK.
- The menu contains 19 installation systems you can
choose from.
- Each one of the systems has a diagram to identify its
operation.
- Use the keys to move on to the next system. To
confirm the chosen system press OK and press the ESC
key to return the previous menu.
- Once the system has been configured, the unit saves the
changes and returns to normal operation.
SYSTEMS
The representation of the units on these diagrams is symbolic.
One solar panel means there is one array of solar collectors, but when there are 2 it means that there is one array of solar
collectors facing east and another facing west.
The accumulator symbols can refer, according to the type of installation, to one accumulator, several accumulators, a
swimming pool, an underfloor heating system, panel exchangers, etc.
The probe symbol indicates which device the probe belongs to.
The resources of the systems are pre-assigned and fixed, which means that each system has a probe and a specific relay
assigned for each element of the selected system. The probes can be shared with the functions, but the relays only operate
exclusively; if a relay is being used by a system it cannot be assigned to a function (except for functions that only need a relay as
a reference: double pump, OR, AND, etc.)
If you configure the functions before the systems, you will see that some of the systems cannot be selected and will not be
shown on the menu. If the system you want is not shown on the menu, it is because a function is activated that needs exclusive
relays and there are not enough relays free. You will have to deactivate a function in order to be able to configure the system.
When the password is activated, the Allegro 576 allows you to consult the types of systems and when you select another
system you will be asked to enter the password to configure the change.

Controls a remote adjustment probe. This probe
regulates the temperature of a room and modifies the
temperature setting without having to configure it in the
Allegro 576.
In installations that use water without coolant as a heat-
transfer liquid, the heat of the installation is used to
prevent the circuit from freezing.
Allows you to double a pump in your installation so that
the two pumps work in alternation.
Allows you to cool a part of the circuit by means of an
independent device or recirculation
It measures the energy supplied by the solar collector to
your installation by means of reading two probes and the
pulse input.
Reduces the reading delay for probes installed outside
the collector by means of brief recirculation.
Controls a valve to increase the temperature of the
heating return circuit to use the solar heat from the
accumulator for heating.
The status of one relay is conditioned by the status of
ANY of the chosen relays. This function is executed after
the AND function.
