Heater Status Menu - Lochinvar 100 Series Instruction Manual

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, for example, Heating, Standby, or Fault. See Table 7
(page 22).
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) provided for external supervisory controls such
as building EMS (Energy Management System). See Wiring
Diagrams (page 43). 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 (for example, 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 (page 34).
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.
