STATUS
Displays the current Operating State of the control system. IE:
Heating, Standby, Fault see Table 7.
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)
