PASSWORD

Default Disabled

The Password is provided to prevent unauthorized users from making changes to the Harmony settings.

Setting up the Password feature is not recommended as it slows down access, makes servicing more difficult, and can disable the system if management or ownership should change.

The Password feature is not active unless a user enables it.

If you choose to enable the Password, DO NOT forget the Pass- word. Write it down and store it in a safe location known to at least one other authorized user.

When the Password is enabled, none of the settings can be changed without entering the Password.

Once the Password is entered, you can make multiple changes. The Password will expire 15 minutes after the last change has been made.

Using the Default Password

The Harmony has a built in default Password - MMOD.

Enabling the default Password will prevent most unauthorized users from adjusting the settings, but will not prevent Lochinvar service personnel, or anyone else with access to this manual, from adjusting the panel.

To enable the default Password, enter the System Settings 2 menu, select Password, and follow the prompts to enable the Password.

At the Login screen, you will have to enter the Password. Turn the ADJUST/SELECT knob until the desired letter is shown. Then select the letter to move on.

Enter MMOD into the Login screen as shown top left.

When completed, select No to the prompt Change Password?
