The following fields are found in the Global Settings section.
Field Name Description
Application
Type
Select the main HVAC system application for this controller. This determines
the algorithm that will be used for the controller.
The options for the eZV-440 are VAV-single duct, VVT and None.
The configurable controller has no functional state until you select an
algorithm.
In a fully programmable controller, when you select an algorithm, you can
override portions of the internal algorithm to suit your needs. See the section
in this guide about overwriting the algorithm. Select None if you want to
program a fully custom sequence of operations. When you select None, the
internal algorithms are disabled and all preconfigured algorithm I/O points and
variables are removed from the default database. Other object types, like AIC,
that were part of the algorithm can be used as is or reconfigured.
If you change an application type for another, the settings of the
previous application type will be deleted. You can save your
controller database before switching application types.
Temperature
Units
Displays the temperature units used by the controller.
Airflow Units
Displays the airflow units used by the eZV-440 controller. Select between
CFM, l/s or m3/h.
In the configuration graphic, when VVT is selected as the application type, the
units are set to percentages which represent the damper min/max positions.
When VAV is selected as the application type, the AV124 to AV127 objects
and the air flow setpoint will use the units set up in the Airflow Units field.
Child
Controller
(enteliWEB
only)
If this controller reports to a parent controller, select this box. The child
controller polls these variables from its parent controller:
l HeatCoolLoad (AV802)
l OccupancyMode (MV800)
l DemandCtrlVent (AV813)
