read by the Mini-MOD sensor, the Last Stage Hold setting must be accounted for. The boiler limit must be set above the Set
Point PLUS the Last Stage Hold PLUS the normal drop experienced in the piping.
Using the previous example of a 10°F Last Stage Hold with a 160°F Set Point, the boilers' limits must be set enough over 170°F
to prevent the boilers' internal limits being reached. In this situation, the boiler high limit should be set at approximately 180°F
to prevent the difference in boiler temperature vs. header temperature causing erratic operation.

DAY/NIGHT SCHEDULES

(Available when "Day/Night Schedules" is selected from the Setback Startup
menu option only)
Button: MENU/<System Settings>/<More Settings>/Day/Night Schedules
The Mini-MOD has two levels of heat. The Day level is used when a building is
occupied and people are active.
The Night (Setback) level is used when a building is not occupied, or when people are
sleeping. This setting reduces the calculated temperature by the Setback setting. If
the Day calculated water temperature was 150˚F and the Setback was 20˚F, the Night
Schedule will run at (150˚F - 20˚F) = 130˚F.
If the Boost feature is being used, it uses the Day Schedule as a Boost ending point. That is, if the Day Schedule is set to start
at 6:00AM, the Boost will start 30 minutes prior to the Day setting at 5:30AM. The Mini-MOD will then raise the calculated
water temperature by the Setback amount. Using the previous example, at 5:30AM the Mini-MOD will raise the calculated
water to 170˚F (150˚F + 20˚F) until 6:00AM.

SET TIME

Button: MENU/<System Settings>/<More Settings>/Set Time
Button: MENU/<System Settings>/<More Settings>/<Day/Night Schedules>/Set Time
Adjust the time by selecting Time from the menu and then scrolling through the hours
followed by the minutes. If hours are to be set to PM, scroll through the AM hours to
reach the PM hours.
Remember that the battery is the backup for the Time. If no power is supplied to the Mini-MOD and
there was no battery or battery had no power, time values will be lost and will need to be reset.

HISTORY

Button: MENU/<Histories>
The Mini-MOD provides users with a graphical history of the System and Outdoor temperatures
for the previous 24 hours. The temperatures are sampled every 12 minutes. That is, readings
of both System and Outdoor temperatures are recorded and stored every 12 minutes for the
last 24 hours.
To view the values of specific time period, use the two middle buttons to scroll to that
time and read the upper left temperature.
The first screen will be the System Temperature History. By clicking on the Next button,
you'll be able to view the Outdoor Temperature History.
