The Stack sensor should be a 1k ohm platinum type sensor.
Part # 0040-1300. To configure the 1k PT Stack sensor,
Switch S5.3 should be set to the NONE position and S5.4 set
to PLATINUM STACK. The sensor will then be auto-
detected after a power cycle.
Security
A password can be used to lock out control and setup
features. It can be enabled, but is shipped in the disabled state
Save/Restore Configuration
Settings
(Firmware V2.0 or greater)
In a complex system, there can be a multitude of settings
necessary for proper boiler operation. These settings can be
saved to the onboard memory.
ADVANCED SETUP:
LOAD DEFAULTS: CONFIG? SAVE.
Saving to the on-board memory is useful when the setup of
the boiler operation is complete, prior to upgrading firmware,
or performing a factory reset.
After a factory reset or firmware update the saved settings
can now be restored.
ADVANCED SETUP: LOAD
DEFAULTS: CONFIG? RESTORE.
USB Features
The HeatNet V3 control supports a USB updating system and
desktop connectivity using the HeatNet Control Pro software.
In order to ensure that a valid firmware file is always
available on the HeatNet board, (2) file storage locations are
available. A firmware file is loaded at the factory in both
locations. This is to ensure that if a bad file is loaded by the
user, the factory loaded file can be re-loaded to get the board
functional again.
The firmware loading menu is located at; ADVANCED
SETUP: SYSTEM: LOAD FIRMWARE. The following
explains the menus.
Selecting
USB DRIVE
will read the FIRMWARE directory
on a flash drive and display any .hex files located there. The
USB flash drive needs to have a directory called “firmware”
located in the root directory. The downloaded firmware .hex
file needs to be placed there. Then the flash drive needs to be
inserted intoJ6 on the HeatNet control board. Follow the on
screen prompts and then select the file using the arrow keys.
Once a file has been selected, a STORAGE LOCATION
needs to be selected. There are (2) storage locations for the
new file. Location 1 is used for normal updates and Location
0 is for the factory stored backup file. When the Storage
location (default is Location 1) is selected the file will be
loaded into a permanent storage memory location. Next, the
control will reboot and copy this new program into running
memory, reboot, load factory defaults, and then reboot again.
Selecting
USB CABLE
requires
connecting a USB cable and
running the Firmware Update program from a PC. This process
takes much longer and requires a Personal Computer (laptop) to be
taken to the boiler site. Again, follow the on screen prompts to down
load the program into a storage location as done when using the
above USB DRIVE loading menu. You will need the HeatNet Pro
software which can be downloaded from the website.
Selecting
SAVE FILE
will display the currently stored files in the
storage memory locations. Use the arrow keys to select a stored file
for copying to running memory. When
SELECT
is pressed the file
will be marked so it will be loaded on the next power cycle. Power
cycle the boiler to begin copying the file from stored memory to
running memory.
NOTE:
to access the factory backup program, the P3
BOOT shunt on the HeatNet control board needs to be
connected and the CAL/NORMAL switch placed in the CAL
position. The BOOT jumper is located close to where the
ribbon cable for the display plugs in. If the control is power
cycled in this condition, the factory program will overwrite
the existing running program. If in the LOAD FIRMWARE
menus, STORAGE LOCATION 0 will be an allowed storage
location. When the download begins, remove the shunt from
P3 and slide the CAL switch to normal.
Saving/Restoring Settings
Selecting SAVE will store the setting in the on-board
memory in the event a firmware update is performed, a
factory reset needs to be done, or the settings are changed in
error and are unknown.
ADVANCED SETUP: LOAD DEFAULTS:
CONFIG?: SAVE
Selecting RESTORE will reload the saved settings.
ADVANCED SETUP: LOAD DEFAULTS:
CONFIG?: RESTORE
Diagnostics
The H-Net control can display and identify faults in a
meaningful way. If an interlock trips, it will be indicated in
the main screen display, along with an audible alarm
(mounted on control board) and a set of relay contacts will
close. A record of this, with a time stamp, will also be
entered into the log as an aide in the diagnosis of the event.
The log can be downloaded and a histogram used to display
