Resetting to Factory Default Values
All user options for the H2TU-C, described in Table 5 on page 18 , can be set to the factory default values using
the MODE and LBK pushbuttons. To set the user options to their default values:
1 Press the LBK pushbutton for 6 seconds until the following message appears:
DFLT NO
2 Press the LBK pushbutton until the DFLT NO message is displayed.
The message changes to DFLT YES indicating the factory default values are now in effect and the display
returns to the normal mode.
To terminate the DFLT mode without setting the factory default values, do one of the following:
• Press the MODE pushbutton to return to the normal display mode.
• Wait 30 seconds for the unit to return to the normal display mode.
Displaying System Parameter Settings

The H2TU-C displays the following parameters:

Disabling an Alarm
System alarms can be disabled by pressing the LBK pushbutton on the H2TU-C front panel. This executes an
ACO and returns the H2TU-C to its non-alarm state. For more information, see

See “Loopback Operation” on page 55 for instructions on using the MODE and LBK pushbuttons to activate
