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.

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.

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.

Displays whether the control system is currently operating in Economy Mode or not.

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.
