Economy Mode Setup Menu - A.O. Smith 100 Series Instruction Manual

ECONOMY MODE SETUP MENU

This menu contains settings used to establish an "Economy Set Point" and "Economy Mode" operating periods. This control system
feature can help reduce operating costs during unoccupied, low load, or peak demand periods.
Setpoint Adjustment - Adjustable user setting from 2°F (1°C)
to 50°F - factory default is 20°F (11°C) the control system uses to
calculate the "Economy Set Point." The Economy Set Point = normal
Operating Set Point minus the programmed Setpoint Adjustment
value. The Economy Set Point is the water temperature the control
system maintains during programmed Economy Mode time periods.
"Economy Set Point" is displayed instead of "Operating Set Point"
and "Economy Mode" appears beneath the current time on the Home
Screen during Economy Mode time periods.
Current Time - Seven Day 24 hr clock. Use this menu item to set the
current time and day of the week. Current day and time are not set
from the factory. "Clock Not Set" will be displayed on the Home until
the time/day has been initially set.
Heater In Economy Mode - Displays whether the control system is
currently operating in Economy Mode or not.
