How to factory reset a TM172 HVAC Controller

Connect to the M172 with the HVAC software.

Open the file browser section found under the "commissioning tab" in the HVAC software.

When the file browser opens the FTP connection to the PLC select all the files on the PLC ad delete them.

This process will reset the PLC to be empty with no project and therefore the PLC will be reset like new.
