Appendix A: TV-VAVB3-E2 Points/Properties
Point Name/Description
Fan – The status of the terminal fan if Term Type is Parallel Fan or Series Fan.
Space Relative Humidity – The current space relative humidity if Service Configuration
> Hardwired Sensor is set to RH Sensor or, you have a valid ZS RH sensor.
Indoor Air Quality CO2 (ppm) – The current IAQ value if Service Configuration >
Hardwired Sensor is set to CO2 Sensor or, you have a valid ZS CO
Shutdown – When Active, disables all control functions, at normal equipment time
delays and maintains minimum airflow.
Hot Wtr Vlv 1 Cmd - The current commanded position of the Act Net valve.
Hot Wtr Vlv 1 Pos - The current position of the Act Net valve.

Point Name/Description
Heat Enable – Enables the reheat function.
Parallel Fan Heat On Delay – Parallel type terminal only. The delay before reheat is
enabled after the zone has a heating demand. The terminal fan runs immediately and
attempts to meet the heating demand using the heated air from the ceiling plenum.
Fan Off Delay – Fan-type terminals only. The amount of time the terminal fan continues
to operate after a heating demand is satisfied.
Maximum Heating SAT – The maximum supply air temperature allowed while ducted
heat is operating. Ducted type supplemental heat is controlled so that it will not exceed
this limit or the configured High SAT Alarm Limit.
Set the Maximum Heating SAT limit to 5°F (2.8°C) above the desired maximum supply
air temperature you would expect. Refer to Alarm Configuration > High SAT Alarm Limit
to properly set this parameter.
Maximum RH Override Airflow – The maximum airflow allowed when the RH function
overrides the temperature control. When active, the damper modulates to the
temperature control requirement or the RH override airflow, whichever is greater. This
value is the percentage of the Maximum Cooling Airflow Setpoint.
