HEATER STATUS MENU

ELECTRONIC CONTROL SYSTEM

HEATER STATUS MENU

This menu displays non adjustable operational information. This menu contains more information that can be displayed on one screen of the LCD display. Use the Up & Down Buttons to navigate to the bottom of this menu.

Status

Top Of Menu

 

Displays the current Operating State of the control system. IE: Heating, Standby, Fault etc. - see Table 2 on page 51.

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

Bottom Of Menu

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 page 42) 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 page 59). 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 - see page x?) is used for building EMS (Energy Management System) notification of operational conditions such as Fault conditions and heating mode status.

Servicing should only be performed by a Qualified Service Agent
