MENUITEM DESCRIPTION
INPUTS ASSIGNED
y Lists all the inputs already assigned to this PRIORITY.
Inputs will be listed as 1, 2, 3.
y Shows NONE if there are no inputs assigned to this
priority .
SYSTEM TYPE
y Select the system type for this PRIORITY, based
on the heating terminal units in the system (see
Figure73,page74). Use the CUSTOM selection to set the
control for a dierent system type. e factory preset val-
ues for SUPPLY MAX, SUPPLY MIN, OD RESET MAX
and OD RESET MIN are chosen based on the normal
best setting for the terminal units.
TARGET MOD
SENSOR
y Choose SYSTEM SUPPLY or BOILER OUT to deter-
mine which will be the primary temperature sensor. e
control will modulate boiler input to reach the TARGET
temperature. (Default is System Supply.) If system sensors
are not used, boiler defaults to using heat exchanger outlet
sensor in place of system sensor.
y Not adjustable in Basic Mode, see Advanced Manual for
information on adjusting this parameter.
TARGET ADJUST
y Select how target temperature is calculated by control:
NONE (no reset, xed target temperature), 0-10V (target
temperature based on analog input from remote source),
ODT (outdoor reset operation; default setting).
y Not adjustable in Basic Mode, see Advanced Manual for
information on adjusting this parameter.
SUPPLY MAX
y Set SUPPLY MAX to the required supply water tempera-
ture for the system at design maximum heat loss (typically
180 °F for nned tube baseboard on new installations.)
SUPPLY MIN
y SUPPLY MIN should equal the desired minimum supply
water temperature for the system.
y is line is not shown on priorities congured as DHW
system type or Heating system type, if outdoor tempera-
ture sensor not used. See Advanced Manual for informa-
tion on adjusting this parameter .
OD RESET MAX
(Not shown for
Priority 1 by default)
y OD RESET MAX is the outdoor temperature at which the
target temperature reaches its minimum (SUPPLY MIN).
y is line is not shown on priorities congured as DHW
system type or Heating system type, if outdoor tempera-
ture sensor not used. See Advanced Manual for informa-
tion on adjusting this parameter .
OD RESET MIN
y OD RESET MIN means the outdoor temperature at
which the target temperature reaches its maximum value
(SUPPLY MAX).
y OD RESET MIN should equal the ODT (outdoor design
temperature) for the installation’s location.
y is line is not shown on priorities congured as DHW
system type or Heating system type, if outdoor tempera-
ture sensor not used. See Advanced Manual for informa-
tion on adjusting this parameter .
