ECONOMY MODE SETUP MENU

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.

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.

Servicing should only be performed by a Qualified Service Agent
