This requires a Bluetooth interface on the PC or Using a PC or notebook and the TROX notebook (either integral hardware or EasyConnect configuration software, you external, e.g. with a USB stick). - Page 23 When the zero point correction is finished, reconnect the measuring tubes. Adaptation of the actuator (only for fast-running actuator TUS) For air terminal units with TROX type HPD actuator (A00000067751), adaptation must be carried out during commissioning. This ensures that any incorrect position, e.g. due to shipping or installation, is corrected.
- Page 24 Commissioning For adaptation, the actuator moves to the end positions and then automatically switches to control mode. Functional test To complete commissioning, perform a func- tional test of the controller using the Easy- Connect software, taking into account the project specifications for the required oper- ating modes.
