Log Entry
The FlexCore CK-Series H-Net control contains a log that
records the major activity (events) in the operation of the
boiler. This activity includes interlock faults, boiler starting
and stopping events, power cycles, misc. faults, and types of
calls-for-heat (control inputs). Setting the time clock to an
accurate time and date is very useful when events are
recorded, since the control will time stamp each snapshot. If
the system is configured to run with HeatNet, then only the
Master boilers SYSTEM TIME needs to be entered. The
Master will then set the time on all Member boilers.
The log is primarily used as a troubleshooting and
diagnostic tool, but may be used as a performance tool to
view run time cycles.
An event in time of the boiler’s state is presented via
multiple screens. Each screen event can be stepped through
using the arrow keys.
The top line, left corner indicates any condition that caused
the event. This may be a fault (such as to indicate a sensor
that has failed.) or general event as denoted by “Event”. The
top line, right corner displays the time and date the event
occurred. In the bottom center of the command bar, the
event # is displayed so that easy indexing can be done using
the arrow keys. The second line from the top displays the
type of heat demand for that event. The next few lines
display the Setpoint, Return, Header, DHW, Supply and
Outside temperatures. The last line displays the Modulation.
The Center middle annunciator shows icons of the boilers in
the system/standalone with graphics indicating if they are
firing. The large arrow buttons on the left and right of the
boiler icons allow the viewing of the control state.
They are the Circulator Pump state, and the ignition
sequence condition (Main Valve, Pilot Valve, Blower, and
the Ignition alarm). There are also indicators for interlocks
and auxiliary functions.
The log may also be viewed using HeatNet Pro or HeatNet
Online.
