 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.
