Honeywell VRX180 Manuale Utente

Security lets you protect certain menu items and functions from unwanted or accidental access.  Access 
to a secured item requires entry of a 3-digit master or operator code. 

Select “PROGRAM SECURITY” to display the Security menu (if security is active, you will be prompted 
to enter the master code before continuing). 

 

If the master or operator’s security code is lost or forgotten, a security bypass procedure is available.  See 
Appendix A. 

 

Table 4-66 describes the Security prompts.
