Control System Operation

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.
Set-Point 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 Set-Point 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 dis-
played on the Home 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 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.
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.
