10.4 View Menu (Home Screen - Default Display)
The
View Menu
is the default display (home screen) of the EOS control system. The View Menu displays general
information about the boiler’s operation and status. The default display includes a Burner Firing Rate % Icon for
modulating units (disregard this icon for fixed rate burners), a Pump Icon that is visible whenever the integral tank
circulator is energized and Failure Messages if the unit is in an alarm or error condition.
Use the
Next Item
and
Item Back
buttons to scroll and view the View Menu Item Fields and their associated values.
The Item Field descriptions are listed below:
Description
CNTL TEMP
Displays the current operating temperature. This is the temperature measured by the sensor
selected by the user to provide water temperature control.
HEAT TARG
Display screen displays the current operating set point but does not allow the user to make
changes in this menu. The Target Temperature is determined by the application mode and
the type of heat call. The BTCII displays the Target Temperature that it is currently trying to
maintain at the control temperature sensor (CNTL TEMP). If there is no current requirement
for heat, the Target Temperature is displayed as "----"
SUPPLY
Displays the current system probe temperature.
VENT
Displays the current flue gas temperature as measured by the flue gas sensor located in the
flue outlet.
Boil OUT
Displays the current temperature at the outlet of the boiler as measured by the operating
control sensor located in the supply fitting.
Boil INLET
Displays the current temperature at the inlet of the boiler as measured by the control sensor
located in the return fitting.
Boil ΔT
Displays the current temperature difference between the Boil OUT and the Boil INLET
sensors.
FLAME CUR
Displays the burner flame current in approximate µA dc. Since this is an approximation it is
recommended that a flame current measurement be taken at the PIM control board. See
section 11.6 Flame current Measurements.
TIME
Displays the real time as programed in the TIME menu.
Indication of burner firing rate as
percentage of turndown range.
