With that thought in mind, should any of the following be password protected functions?

1. Manual defrost
2. Suction pressure set point
3. Condenser fan set point
4. Floating points
5. Acknowledging alarms
6. Force compressor run
I would suggest all except number 1 but are we trying to protect the equipment and product from attack by either the end user or the dubious mechanic?

Good point, Brian. What are the purposes of passwords? I would like to think they protect the equipment being adjusted by competitors, or ill-willed ex-employees, and certainly store personnel. There have been times that I would have liked to use them to protect the equipment from service techs too.

Conversely, I have had competent technicians frustrated that they couldn't effectively respond to an emergency service call because they couldn't get the password.

But I agree. Manual defrost is a good one to keep available to everybody, as long as it cycles properly out of defrost during it's alloted time span.
