4-20mA.
If the INPUT TYPE is set to BMS, a Flow Limited or a Boilers
Limited method can be used. With Flow limited a GPM value can
be written to the BMS GPM Modbus register 40019 with a valid
flow. If the Boilers Limited method is to be used, the number of
boilers that the BMS would allow HeatNet to control is written into
Modbus register 40020.
See the Flow Options section for more details.
SET PARAMETERS
LOWEST FLOW

LOAD FIRMWARE
NO
Enters the Load Firmware menu. Loading new firmware allows for
upgrades and bug fixes to the HeatNet control. See the SOURCE

USB DRIVE,
USB CABLE,
SAVE FILE
Selecting
USB DRIVE
will read the FIRMWARE directory on a
flash drive and display any .hex files located there. Follow the on
screen prompts and then select a 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 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.
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 control needs to be connected and the CAL/NORMAL
