Nice THA5 Control Board

Nice THA5 Control Board — Thor 1500 Motor System Replacement Control Unit

Nice THA5 is the original replacement control board manufactured for Nice Thor 1500 series industrial door motors. The board operates with a 220V AC input voltage and 220V motor output, and features dedicated output terminals for photocell, flasher, button, and safety edge connections. With an IP54 protection rating, its dust- and water splash-resistant construction allows reliable use in both indoor and outdoor applications. The wide operating temperature range of -20°C to +55°C ensures stable performance even under harsh climatic conditions. The BlueBus technology integrated on the board allows accessories to be connected to the system using only two conductors, significantly reducing wiring complexity. Advanced motion management functions such as soft start, controlled stop, and programmable automatic closing extend the service life of the door system while enhancing safety during daily operations. The THA5 is compatible with Nice Era Inti 2, Era FLO2RE, Era ON2E, Era ON4E, and Nice Mygo 4 remote control accessories that are compatible with the TH1551 control board.

Replacing the Nice THA5 control board is rated at a MEDIUM difficulty level. While the removal and installation of the board can be performed with standard hand tools, it is necessary to ensure that all terminal connections are made completely and in the correct order, that BlueBus device addressing is reconfigured, and that any DIP switch settings are matched to the previous configuration. For this reason, it is recommended that the procedure be carried out by a technician experienced in door automation systems or by an authorized service provider; incorrect wiring may result in accessories not being recognized or motor protection circuits being triggered.

Nice S.p.A. is one of Europe's leading manufacturers of door and barrier automation systems, and all spare parts are brought to market after passing factory quality control processes.
