Default Settings & Menu Item Descriptions — ADVANCED SETUP
DISTRIBUTED CTRL
CONTROL
H-Net
Displays method of operation: HeatNet (H-Net)
H-Net MASTER
YES
Auto detected, based on the HEADER sensor.
If the HEADER sensor is present and is set to TYPEZ, the Futera
III/Fusion-Series control is run as a H-Net MASTER (YES).
If the HEADER sensor is not TYPEZ, H-Net MASTER = NO.
MASTER TYPE
AUTO
AUTO, COMBO,
DHW
Two PID controls are provided, one for Space heating and one for
DHW heating. This menu item selects how they are to be used. The
MASTER TYPE setting is used to determine if the MASTER control
is to be used as a space heating control, a COMBO DHW/space
heating control, or just to perform DHW Heating.
When set to AUTO, the boiler uses one PID control to provide space
heating. When set to COMBO, the control will use two independent
PID controls to provide space heating and DHW heating. When set
to DHW, the control only uses the DHW PID control.
H-NET ADDRESS
255
2 –16
The local address is the address of a Member device. This is
normally in the range of 2 through 16. But if the Futera III/Fusion-
Series control is a MASTER, then the default address is 255. The H-
NET ADDRESS # is synonymous with boiler #.
MODBUS ADDRESS
1
1 – 247
The MODBUS address is for communicating with Laptop, PC, or
other MODBUS capable device, such as a Building Management
System. It is the 2nd communication port reserved for host control.
MODULAR BOILER SET
SPACE HEATING
DHW HEATING
If the MASTER TYPE is set to COMBO, the MODULAR BOILER
SET is duplicated for each PID. Select SPACE HEATING to set the
ADD, SHED, MODULATE, and MOD MAX values for the space
heating PID. Then select DHW HEATING to set the ADD, SHED,
MODULATE, and MOD MAX values for the DHW heating PID.
ADD BOILER DELAY
10mins
0 – 60min
This is the delay time in 30sec intervals, before starting a new boiler.
Boiler #1 is started immediately after a call for heat. If a second
boiler needs to start, the ADD BOILER DELAY will need to expire
before starting.
SHED BOILER DELAY
2mins
0-15min
This is the delay time in 30 second intervals, before stopping a
boiler. A boiler is stopped immediately when the top of the heat band
is exceeded. If a second boiler needs to stop, the SHEDBOILER
DELAY will need to expire before stopping.
MODULATE DELAY
TIME
10 secs
0 – 60min
This is the time the boiler remains in min-fire before it relinquishes
control to the modulation % signal.
MOD MAX – LAST FIRE
70%
25 – 100%
This value represents the maximum % of input on the boilers if all
the available boilers are not firing. Once all boilers are firing, this
clamp is removed and all boilers are allowed to modulate up to
100%. When this value is limiting the input an ‘*’ is displayed and
the “INPUT CLAMP” message is displayed in the STATUS screen.
This value is derived by: multiplying twice the minimum fire rate of
the boiler with the least turndown (2* turndown (20% 5:1, 25% 4:1,
33% 3:1)).
