• SYSTEM TYPE – Read only (assigned in
previous step).
•
TARGET MOD SENSOR – Read only for
network boilers, adjustable for single boil-
ers – Shows which sensor reading is used for
modulation. Boiler sensor is default for local
priorities. System sensor is default for network
priorities.
•
TARGET ADJUST – Select how target tem-
perature is calculated —
NONE (no reset, fixed target temperature =
SUPPLY MAX)
ODT (outdoor reset operation; default setting).
Target temperature is calculated from the
outdoor reset curve. SUPPLY MAX is target
temperature when outside temperature equals
OD RESET MAX. SUPPLY MIN is target
temperature when outside temperature equals
OD RESET MIN. At outdoor temperatures in
between, target temperature is scaled propor-
tionally. See Figure 1, page 5 for details.
0–10V (target temperature based on input
from remote source). SUPPLY MAX is target
temperature at VOLTS FOR MAX value. SUP-
PLY MIN is target temperature at VOLTS FOR
MIN value. For voltage values between max
and min, target temperature is scaled propor-
tionally. See Figure 2, page 5 for details.
•
SUPPLY MAX – Set SUPPLY MAX to the
required supply water temperature for the
system at design maximum heat loss (typi-
cally 180°F for finned tube baseboard on new
installations.)
•
SUPPLY MIN – SUPPLY MIN should equal the
desired minimum supply water temperature
for the system. This line will not show if Target
Adjust is selected as NONE.
•
OD RESET MAX – means the outdoor temper-
ature at which the target temperature reaches
its minimum (SUPPLY MIN). (Does not ap-
pear if 0–10V is selected for Target Adjust.)
•
OD RESET MIN – means the outdoor tempera-
ture at which the target temperature reaches its
maximum value (SUPPLY MAX). (Does not
appear if 0–10V is selected for Target Adjust.)
•
VOLTS FOR MAX – Appears if 0–10V is
selected for Target Adjust. Set the voltage at
which SUPPLY MAX temperature is required.
•
VOLTS FOR MIN – Appears if 0–10V is selected
for TARGET ADJUST. Set the voltage at which
SUPPLY MIN temperature is required. For
voltages between Min and Max, the target
temperature will be adjusted on a linear curve.
•
BOOST TIME – Every time the call for heat
surpasses this duration of time the target temp
will boost up 10F. It will cap off at Supply Max.
•
RUN BOILER PUMP – Selects whether the
Boiler Pump is turned on while running on
this call for heat. This setting is YES for net-
work priorities and is not adjustable.
•
RUN AUX PUMP/ OUT – Selects whether
Inputs/Outputs in the system configured as
AUX PUMP/OUTPUT are turned on while
running on this call for heat.
•
MAX ON TIME / MIN ON TIME – Maximum
or minimum time the network will run on this
priority if it is being asked to run on another
network priority. MAX shows for Network
Priority 1, MIN shows for Network Priority 2.
This line ONLY shows on the Master boiler
Wizard. It does not appear on Shadow boilers.
