Parameter Description
Box Code Input the VAV box code.
Duct Heat Stages
The number of duct heater reheat stages:
None
– No duct heater reheat)
3 stages
– Duct heater reheat on heat sources 1, 2, and 3)
2 stages
– Duct heater reheat on heat sources 1, and 2)
1 stage
– Duct heater reheat on heat source 1).
If no duct heaters or only perimeter heat is required, set this variable to “None”. All heat
types configured greater than Duct Heat Stages are considered perimeter heaters.
Hot Water Reheat Duct heater reheat by hot water coil (True) or not (False).
Dual Maximum Flow Control
Determine whether the VAV box uses the dual maximum control settings or not.
Note that if using the dual maximum option, a discharge temperature sensor is required.
Floating Drive Time
The floating valve drive time which can be set to 25, 30, 50, 60, 95, 125, or 150 seconds
or to a custom float time. The custom float time is then manually set in the Custom
Floating Drive Time parameter.
Damper Direction
The direction in which the actuator rotates to open the damper (clockwise or counter
clockwise).
VVT Mode Determine whether the VAV box is using flow input or not.
Configuring Room Sensors
Allure EC-Smart-Vue and Allure EC-Smart-Comfort or EC-Smart-Air configuration setpoint parameters
are found in the
Room Sensors
subsection of the
Hardware Configuration
tab. The table below gives a
brief description of each type of configuration parameter.

Parameter Description
EC-Smart-Vue Permissions
Defines how much access a user of the Allure EC-Smart-Vue has to the controller’s
configuration parameters. The Allure EC-Smart-Vue access ranges from full access to
limited access or no access at all. Limited access allows setpoint adjustment only or
setpoint adjustment and airflow balancing.
Regardless of the access level of the Allure EC-Smart-Vue, the controller’s configuration
parameters cannot be modified through the Allure EC-Smart-Vue except after a password
is entered.
EC-Smart-Vue Setpoint Type
Set the EC-Smart-Vue setpoint control to either SpOffset (room temperature setpoint
offset) or Cool Heat SP (cooling and heating dual setpoint).
Elevation
For accurate CO
2
concentration levels, input geographic elevation here if elevation is
greater than 500ft (152m) above sea level. By default, the sensor is factory calibrated to
sea level.
EC-Smart-Comfort/Air Sleep Time Enter the amount of time before the sensor goes into standby mode.
