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 M4 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 M4 will then raise the calculated water
temperature by the Setback amount. Using the previous example, at 5:30AM the M4 will raise the calculated water to 170˚F
(150˚F + 20˚F) until 6:00AM.

The M4 provides users with a graphical history of the System and Outdoor temperatures for

both System and Outdoor temperatures are recorded and stored every 12 minutes for the last
24 hours.

time and read the upper left temperature.
