Change Parameter Settings - Ace Heating Solutions Atlas A050 Operating And Maintenance Manual

The Honeywell Sola Controller on each boiler also maintains a password time out that limits the scope of the password
entry. Once a password is successfully entered the unit starts an internal timer that expires after 10 minutes of inactivity.
After the timer expires, the user is required to re-enter a password before a parameter can be changed. The user is not
required to enter a configuration password for a parameter that has a lower access level than the access level achieved
by an earlier password entry for any configuration group as long as the user stays in the configuration pages. The user
only needs to enter a password once until a parameter that has a higher access level is selected. The user enters the
password from a keyboard. After the password is entered, the OK button is selected. The Cancel button aborts the
password login.
Three levels of write access to boiler parameters are permitted. Each access level has defined rights when interfacing
with configuration and status parameters.
x
End user: The lowest access rights and no password login is needed. The end user can, in most cases, only read
or view boiler parameters. In some instances the end user can change operation related parameters.
x
Installer: The next highest level. The installer can read all the parameters and change installation related
parameters for boiler parameters. This access level is used to customize the controls for a particular installation.
Refer to CHAPTER 5 – INSTALLER INTEGRATION GUIDE for more detail.
x
OEM: The highest access level. Ace OEM level parameters are not accessible by end user or installer.
Different passwords exist for each access level. The End User level requires no password, but the Installer and OEM
levels have unique passwords defined for them.
WARNING - Explosion Hazard Improper configuration can cause fuel buildup and explosion.
Improper user operation may result in PROPERTY LOSS, PHYSICAL INJURY or DEATH. The
Operator Interface Display used to change parameters must be attempted by only experienced
and/or licensed burner/boiler operators and mechanics.

4-10 Change Parameter Settings

Change parameter settings by selecting the parameter on the page. A dialog box displays for the parameter with controls
allowing the user to change the value as in Figure 4.10. After changing the setting to a new value, press the OK button.
Pressing the Cancel button leaves the parameter unchanged. The changed setting is reflected on the screen and sent to
the controller when the OK button is pressed.
