OPTIONAL FEATURES
HeatNet Control V3 2.x
To activate this flow limited feature for use with an Onicon
Flow Meter F-1210:
a.
Set SETTINGS: FLOW METER: ENABLED: YES
b.
Set SETTINGS: FLOW METER: GLYCOL MIX
% , Currently, any mix over 10% de-rates the flow
by 30% (rule of thumb method). Example: if the
LOWEST FLOW = 50 GPM, HeatNet will calculate
a New Lowest Flow required to be 65 GPM. The
LOWEST FLOW does not need to be changed, but is
calculated to 65 GPM and that value is used by
HeatNet.
c.
Set SETTINGS: FLOW METER: INPUT TYPE to
mA 2 or VOLTS 2 depending on whether a 4-20
milliamp or 0-10 volt signal is used. The connection
should be made from the Flow Meter to analog input
4-20 mA (2).
d.
Select SETTINGS FLOW METER: LOWEST
FLOW: (The automatic value loaded will equal the
lowest flow required for this boiler (it is adjustable).
It should be equal to the lowest flow of the largest
boiler in the system).
e.
Set the SETTINGS: FLOW METER: FULL SCALE
value to the full scale reading on the calibration card
that came with the flow meter.
f.
The HIGHEST FLOW & FLOW FACTOR currently
are not used with this release.
g.
These settings will use the equations:
4-20 mA: Measured GPM = (signal/16) * FULL
SCALE flow
0-10 Volt: Measured GPM = (signal/10) * FULL
SCALE flow
These settings may work with other flow meters
(consult their respective manuals).
HeatNet Online
HeatNet Online is a web based system for fault notification,
monitoring and tuning of a HeatNet based system. A
HeatNet Online bridge module is required to connect a
boiler (Usually the Master boiler) to the internet. The
bridge is available for version 2.x and version 3.x HeatNet
controls and is standard on V3.x. The bridge module
provides an RJ45 connector for access to the internet. If an
RJ45 hardline is not available, a wireless modem can also
be used. Consult the factory or sales for available solutions.
The HeatNet Online site may be accessed at:
www.heatnet.net/
. A login Account/Password is
required.
Once a user has registered a site, the users email can be set
up to provide daily status messages and fault/alarm emails
within minutes of trouble. This provides a valuable tool for
technicians on the road. If the technician has a smart phone,
they can be notified through the emails on their phone.
They can then log on to the HeatNet Online website (from
their phone) to determine the trouble. Sample email

Data
Once the user has logged in, a selection screen for the
building sites the user has registered will be displayed.
When a building site is selected, the main Live screen will
be entered. This is the HOME screen and provides a quick
view on the status of the site.
Selecting the History tab allows a runtime Histogram of the
system. The histogram displays temperatures and states of
the system in a date/time format. Also displayed is the
Master boiler log, faults, messages, modulation, and events.
To the right of the histogram is the Master Boiler‟s log.
Since the HeatNet bridge only transmits at 1 minute
intervals, the log can be used to precisely view the state of
the boiler at the time of the event (in-between minutes).
This screen is an excellent way to diagnose system
problems and tune systems for optimal performance.
