The following table describes the attributes used by the Unoccupied Sequencing (UV) v100 module.

Table 1. Unoccupied Sequencing (UV) Attributes

Name

Type 1

Description

Default Value

Differential

 

Amount Zone Temperature must exceed Unoccupied Setpoint to stop unoccupied control.

 

Low OA Temperature Diff

 

Contains the differential for the Low OA Temperature mode. Once the unocc status has been set to Low OAT, the outdoor air temperature must rise above the Low OA Temperature Setpoint by this amount to switch out of this mode.

0.5 °C, 1 °F

Monitor OA During Unoccupied

 

Set to True if operation of the heating valve is required when outdoor air temperature is cold during unoccupied.

False

OALL-SP (Low OA Temperature Setpoint)

 

Specifies that when the outdoor air temperature drops below this, and monitor OA during unoccupied is true, the Unocc Status is set to LOW OAT.

0 °C, 32 °F

Occupancy

 

Contains the current Occupancy mode as determined by Occupancy Mode Determination.

Occupied

Set Name: Occ Effective

Off During Unoccupied

  Sets the unoccupancy scheme. False

Outdoor Air Temperature

 

Used to decide if the heating valve should be opened based on low outdoor air temperature.

22 °C, 72 °F

Satisfied Timer Duration

 

Length of time that the Zone Temperature must be within the limits before switching to Satisfied.

30 Seconds

State

V

Current state of the hybrid activity.

Set Name: COM Unocc Status State

Unocc Cooling Setpoint

 

Contains the desired unoccupied cooling temperature setpoint.

28 °C, 82 °F

Unocc Heating Setpoint

 

Desired unoccupied heating temperature setpoint.

16 °C, 61 °F

Unocc Status

V, G

Contains the current unoccupied status.

Set Name: UV Unocc Status

WarmupCooldown

 

Current WarmupCooldown State.

Normal

Set Name: OST Warmup Cooldown

Zone Temperature

 

Current Zone Temperature.

22 °C, 72 °F

1 C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and Commissioning Modes Only, V - Calculated Value (Outputs)
