FEATURES & SPECIFICATIONS
HeatNet Control V3 3.x
Page 9
Return (Boiler Inlet) Temperature, and Header
(Common System Supply) Temperature.
9.
Automatically detects the optional temperature sensors
on power up (OAT sensor manual enable in “Settings”
menu “Sensors”) on firmware V2.50 or greater.
10.
Menu driven calibration and setup menus with a bright
Color LCD Touchscreen Display.
11.
(8) Dedicated 24vac interlock monitors, and 8 dedicated
120vac system monitors used for diagnostics and
providing feedback of faults and system status.
12.
Multiple circulator pump control modes.
13.
Combustion Air Damper control with proof time,
support for a common combustion air damper.
14.
USB/RS485 network plug-in to allow firmware updates
or custom configurations.
15.
Optional BACnet or LonWorks interface.
16.
Alarm Relay dry contacts, and Audible Alarm.
17.
Runtime hours, and Cycles (based on Main Valve
Open).
18.
Outdoor Air Reset with programmable setpoint and
ratio.
19.
Time of Day clock to provide up to (4) night setback
temperatures.
20.
Failsafe mode when a Building Management System is
controlling setpoint. If communications is lost, the
boiler/system automatically transfers to local boiler
setpoint control.
21.
Rotation Methods (Lead-Lag): True Rotation (based on
boiler runtime) is default. First On First Off (FOFO),
Last-On First-Off (LOFO) and MIXED are optional.
22.
Programmable password protection to secure the
programmable settings.
23.
Remote 4-20mA setpoint control using a mapped
setpoint range to the 4-20mA control signal.
24.
Freeze Protection allowing automatic starting of
boiler(s) using (2) Failsafe modes.
25.
Adaptive Modulation. When additional boilers are
called, the MASTER adjusts all boilers fire rates to
compensate.
26.
Mixed boiler types in a system.
27.
Support for Domestic Hot Water (DHW) using a 10k
Sensor or a dry contact input from a tank thermostat.
28.
Domestic Hot Water relay for use with a pump or
valve.
29.
On-board power and socket for Protocessor
BACnet/LonWorks module.
30.
HI/LO relay control option from connector J4
31.
Resettable Fused interlock power circuit.
32.
Additional terminal connector for H-Net shielded cable.
33.
Backwards compatible to Version 1.x hardware.
34.
Communications board integrated with the main board
from version 1.x control.
35.
Base Loading of (1) boiler per each boiler on network.
36.
Delayed Blower Power staging. Used to minimize
inrush currents by powering the blower 7 seconds after
main power.
37.
Domestic Hot Water time out for maximum DHW
runtime.
38.
Added support for adjustable space heating and DHW
PIDs. There is now a PID rate setting that can be used
to speed up or slow down the PID response time. The
rate is a selectable Value from 2 – 10, KN boilers
default to 8.
39. Limited the rate that the 4-20mA direct modulation can
change based on the new space heating adjustable PID
rate setting.
