(Available when "Shutdown or Tstat" is selected from the Shutdown/
Tstat/Setback Startup menu option only)
Button: MENU///Day/Night Schedule
• The M4-CNC has two levels of heat. The Day (Normal) 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. See
"Setback" on page 24. 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 the Boost ending point. See "Boost Mode" on page 20. 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 M4-CNC will then
raise the calculated water temperature by the Setback amount. Using the previous example, at 5:30AM the M4-CNC will raise the
calculated water to 170˚F = (150˚F + 20˚F) until 6:00AM.
SET TiME
Button: MENU///Set Time
• Adjust the time by selecting Set Time from the menu and then scrolling through the hours
then select Save. Then, scroll through the minutes then select Save. If the hours are to be
set to PM, scroll through the AM hours to reach the PM hours.

ALERT
Remember that the battery is the backup for the Time. If no power is supplied to the M4-CNC and
there was no battery or the battery had no power, time values will be lost and will need to be reset.
HiSTORY
Button: MENU/
The M4-CNC 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.
