ELECTRONIC CONTROL SYSTEM
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 (2°F to 50°F - factory
default is 20°F) 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 Desktop 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 Desktop until the time/day has been
initially set. Note: the time will not self adjust
for Daylight Savings time.
Heater In Economy Mode
Displays whether the control system is currently operating in Economy Mode or not.
Daily Operating Mode (Sun - Mon - Tue - Wed - Thu - Fri - Sat)
Seven daily sub menus are listed at the bottom of the Economy Mode Setup menu. There
are 3 Operating Modes in each sub menu; “Normal Operation All Day” - “Economy Mode All
Day” and “Normal Operation Between.” Only one Operating Mode can be active, the factory
default is Normal Operation All Day.
Normal Operation All Day: When this operating mode is active the normal Operating Set
Point (Temperatures Menu - page 52) is used for the entire day.
Economy Mode All Day: When this operating mode is active the Economy Set Point is
used for the entire day. Economy Set Point = normal Operating Set Point minus the
programmed Setpoint Adjustment value.
Normal Operation Between: When this operating mode is active there will also be start
and stop times to program. The normal Operating Set Point is used between the
programmed start and stop times and the Economy Set Point will be in effect during the rest
of the day. There is one start time and one stop time event per day.
