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
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
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
