Button: MENU/Setback
• The Setback feature can be used to provide the SQ-Elite-8S with a lower Set Point
when less load is required during the night or on the weekends when the building is not
occupied, but heat is still required.
• The new Set Point will appear on the main display indicating this condition "Setback to 5 Psi".
• For example, if the pressure set point is 8 Psi and the Setback is 3 Psi, then when in Setback, the SQ-Elite-8S will hold a Set
Point of 5 Psi.

day/nIgHt scHedules

Button: MENU/<System Settings>/<Setback Schedule>/Day Schedules
• The SQ-Elite 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 set point by the Setback setting. If the Day calculated
pressure was 8 Psi and the Setback was 3 Psi, the Night Schedule will run at (8 Psi -
3Psi) = 5 Psi.
