Clock, Timer, and Setback Functions
(C-Series)
C-Series ENERGYSAVERS® have two primary methods of operation:
• Exclusively as a thermostatically controlled furnace
• When left to operate on a continuous-run basis using feedback from its
thermostat, the ENERGYSAVER will achieve an optimum balance between
comfort and efficiency.
• As a programmable furnace with two separate timers and a setback function
• The timers allow two separate heating events to be set
• Timer 1 and Timer 2 (individually or both as needed) can then be engaged to
allow the unit to turn on and off for those events
• The ENERGYSAVER is designed to attempt to have the area at the set point
temperature when the timer event begins—meaning it could turn on several
minutes earlier to achieve set point temperature
• To set the clock and timers, see the installation manual
