Hybrid / Heat Unit System
In hybrid brine systems (geothermal-aerothermal), it displays the inlet and return
temperatures and the percentage of energy absorption in each brine system. It also
displays the air-antifreeze temperature difference, the aerothermal operating factor and
the estimated starting point of the defrost program.
In exclusively aerothermal brine systems, it only displays aerothermal information.

1.
Defrost takes place by means of a heat exchange integrated in the ecoGEO heat pump and a stopped compressor.
2.
Always consult regional regulations before using the antifreeze agent.
3.
Adjust the freeze temperature to the type of installation and configure the corresponding protections. Prepare the
antifreeze-water mixture in the proper proportion to obtain the necessary freeze temperature.
