For the correct management of the plant, it will be the responsibility of the installer to use
the defrost output, that must allow the opening of the cycle inversion electrovalve and the
closing of the liquid electrovalve.
For the capillary plants (without thermostatic valve) it is sufficient to control the cycle
inversion electrovalve using the defrosting relay control.
