Log Entry
To access the Log Files, press and hold, the “Back” button
for 5 seconds, the control will beep once. There are three
menu options, SETUP, ADVANCED SETUP, and VIEW
LOG. Place the curser in front of the VIEW LOG menu
item and press “Select”.
The Futera III/Fusion-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 displays the time and date the event occurred.
In the top right corner, the event # is displayed so that easy
indexing can be done using the arrow keys. The second line
displays the Water temperature of the boiler’s output
(supply) and the Setpoint temperature. The third line
displays the Outside Air temperature, and the Modulation.
The bottom line is used to record the control state of the
boiler.
The control state is defined as the Boiler(s) that is running,
the Circulator Pump state, and the ignition condition (Main
Valve, Pilot Valve, Blower, and the Ignition alarm). The #
of boilers that are displayed is limited to 7 if the boiler is the
MASTER. If boilers #8 and up need to be viewed, the
Boiler Control Pro software will need to be used. The Last
2 characters on the fourth line indicate the heating mode the
control is in. The modes are:
NC = No Call for Heat
HD = Heat Demand (MASTER and Local modulation
control using PID control, MASTER and
MEMBER)
RM = Remote Modulation from 4-20mA input
HF = High Fire from ALL T-inputs closed or the AA
input
1T = Low Fire from any 1 T-input closed (Low Fire or
High Fire)
2T = Mid Fire from any 2 T-inputs closed (Low fire or
High Fire )
OP = Option input Active
HT = H-Net Control using the Heat-Link
communications cable
The bottom line is also used to indicate an interlock or limit
that has tripped. It may also indicate a sensor that has failed.
When this occurs, the normal bottom line in the display is
not visible, and the sensor fault is displayed.
For details on messages that appear on the fourth line: See
Appendix B.
The log may also be viewed using HeatNet Pro or HeatNet
Online.
