Password level 1 / PS1
Password Level 2 / PS2
Password Level 3 / PS3
These assign passwords to the three levels of access. The password is a 
three-digit number. Access levels are Shop, Service and OEM. 
You may not therefore have access to change all the passwords. 
Passwords are entered by using the up and down arrow buttons.
Danfoss advises against using passwords which are easy to remember 
or enter, for example 111, 222, 123 etc.

NOTE: When accessing the controller with 3 wrong password in a sequence 
ERC will automatically block access for 15 minutes.
