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 are 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/0-10VDC setpoint control using a
mapped setpoint range to the 4-20mA/0-10VDC 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.
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, Torus 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.
