Point Name/Description
Default/Range
Terminal Type
– The type of zone terminal that the controller is installed on. Not
available for VAVB1.
D:
R:
Single Duct
Single Duct
Parallel
Series Fan
Terminal Size
– Shows the value entered as the
Cooling Max Airflow
in the
Flow Control
object.
D:
R:
2100 cfm
(991.2 liters/second)
0 to 99999 cfm
(liters/second)
Terminal Fan Airflow
– Enter the terminal fan airflow in cfm (liters/second). Used in
performance calculations only. Available only on fan-enabled terminal box.
D:
R:
1000 cfm
(472 liters/second)
0 to 99999 cfm
(liters/second)
Disable Series Fan
– When set to
Enable
, the controller disables the fan on a series-
type terminal when the airflow setpoint equals 0. (We do not recommend configuring
the minimum occupied airflow setpoint to 0, as this does not meet minimum ventilation
requirements.)

Enable
External Actuator Enable
– Enable if the controller's analog output is used for an
external high-torque or slave actuator. Enabling this setting disables the output for
Modulating Hot Water or Combination reheat functions.

Disable/Enable
Heat Type
– The type of supplemental reheat that the zone controller will control. The
heat may be used with system heat, depending on the space temperature demand.
Options:
None
– no heat
Modulating
– ducted or baseboard modulating hot water
Two Position
– two position hot water
Staged EH
– ducted or baseboard electric heat
Combination
– combination baseboard modulating hot water and ducted staged
electric heat
CV Modulating
– constant volume modulating reheat used for single duct terminal
application with modulating hot water reheat (typically used in hospital applications)
SCR Electric
– modulating control for SCR-type electric heater

Ducted Heat
– Determines whether the zone is using ducted heat or baseboard. If
Heat
Type
is
Combination
, set this field to
Yes
for ducted heat.
D:
R:
Yes
No/Yes
VAV Reheat
– If set to
Enable
and
Heat Type
is
Modulating
, a need for heat first
modulates the supply air temperature up to the configured
Maximum Heating SAT
(95ºF [35°C] default). A further heating demand will increase the airflow from the
minimum rate up to the configured
Auxiliary Heat Min Airflow
. Applicable to single duct
terminals only.
