The Allegro 786 Modulating is a regulator for the collection of solar thermal energy that provides you with the necessary resources to manage your installation. 8 PT1000 probes with a high supported temperature range, 6 SPST relays and 1 0-10V PID output for the room thermostat and independent thermostat functions, with mixing valve.

It also has three independent inputs for litre counters (by impulses) for the Energy Counter function, this allows you to control three parts of the installation separately and to know the energy contribution made by the solar collectors to the installation.

It is also equipped with the LEGIONELA function, which allows it to manage high-temperature cycles for antibacterial sanitary treatments.
