Galletti fan coil error codes

The codes below are compiled from the manufacturer's user and service documentation. Codes may vary by model, controller and board version; the safest approach is to send us a photo of the code on your unit's display.

EVO / EVO-2-TOUCH controller

Instead of numbered codes, "probe alarm" (air or water sensor) and "no RS485 communication" warnings are shown. Fix: check the probe wiring and polarity, the board power supply (STATUS LED) and the RS485 line.
