Top of Menu

Bottom of Menu

Status

Displays the current Operating State of the control system. IE: Heating, Standby, Fault see Table 2.

Element Banks On

Displays the current number of heating element Banks the control system has energized. Each Bank of elements contains 3 heating elements.

ECO Contact

Displays the current state of the ECO high temperature limit switch contacts. The ECO switch is located inside the immersion Temperature Probe (two red wires).

Enable / Disable 1 & 2

Displays the current state, open or closed, of the two Enable/Disable circuits (J7 socket on the CCB - see wiring diagrams) provided for external supervisory controls such as building EMS (Energy Management System). Both of these Enable/Disable circuits must be closed to “enable” heating operation. If either Enable/Disable circuit is open for any reason heating operation will be “disabled.” There is a plug with two jumper wires installed from the factory in the CCB J7 socket to enable heating operation when external controls are not in use.

Service Note: If a supervisory control(s) is used to enable/disable heating operation, install field wiring between the J7 socket on the CCB and a set of “dry contacts” on the external control per all applicable building codes. This is a switching circuit only: DO NOT apply any external voltage or connect any load (IE: relay coil) to either circuit.

Element Bank On

Displays the on/off status of each Bank of heating elements. Yes = On, No = Off.

Alarm Condition

Displays the status of the user definable Alarm Output function - see Alarm Output Setup Menu. Yes = alarm condition has been met, No

=alarm condition has not been met.

Alarm Relay Output

Displays the state of the normally open contacts of the Alarm Output relay. This relay (J3 contacts on the CCB) is used for building EMS (Energy Management System) notification of operational conditions such as Fault conditions.

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.

Desktop Screen During Economy Mode

Economy Mode Setup Menu

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.

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;
