These are the times at which the SH Night Setback and DHW Night Setback Offsets become active and inactive. There
are seven (7) stop times and seven (7) start times each for the SH and DHW night setback functions. Any start or stop
time may be set to any time during the week. When a start time and a stop time are programmed for the same day and
time, the stop time has priority (this is how a start time can be disabled). The installer can adjust the SH Night Setback
start and stop times by accessing the parameter SH NSB On/Off Times. The installer can access the DHW Night
Setback start and stop times by accessing the DHW NSB On/Off Times parameter. These settings can be adjusted as
follows:
1.
When the screen is first accessed, start and stop triggers 1 are displayed. If a different trigger number is
desired, rotate the NAVIGATION dial until the desired trigger number appears. Once it is found, press the
NAVIGATION dial to adjust the start and stop times. The day of the week for the start time will flash.
2. Rotate the NAVIGATION dial to adjust the day of the week of the start trigger. Once it is set to the desired
day of the week, press the NAVIGATION dial again. The start time hour will flash.
3. Rotate the NAVIGATION dial to adjust the start time hour to the desired time. Press the NAVIGATION dial
again. The start time minutes will flash.
4. This process may be continued until the start and stop days and times are adjusted as desired. When finished
with this set of triggers, press the [SAVE] key.
5. Rotate the NAVIGATION dial to select another set of start and stop triggers, or press the [EXIT] key to return
to the previous menu.

Any Night Setback On trigger currently active or scheduled within the next seven (7) days can be skipped. To skip a
trigger, go to the Night Setback Status Screen and press the SKIP button. Rotate the NAVIGATION dial until the arrow
(>) is next to the trigger you wish to skip. Press the NAVIGATION dial once. “SK” will appear next to that trigger to
indicate that it will be skipped. You can restore an upcoming trigger by selecting that trigger, and pressing the
NAVIGATION dial again. The “SK” next to that trigger will disappear.
To save any changes and return to the Home Screen, press the RIGHT SELECT [HOME] key. To return to the Status
Screen without saving the changes, press the LEFT SELECT [EXIT] key.
