DHumiLCK

 

Dehumidification lockout 
 
Default value: 

On = Authorized

 

Conditional parameter to Humidity models VTR735xX5x00(X)

 

Typically toggled through the network. 
This variable enables or disables dehumidification based on central network 
requirements from the BAS front end 

 

On = 

Dehumidification Authorized 

 

Off = 

Dehumidification Not Authorized 

%RH set

 

Dehumidification setpoint 
Default is 

50 % RH

 

Conditional parameter to Humidity models VTR735xX5x00(X)

 

Used only if dehumidification sequence is enabled: 
Range is: 

30-95% RH  

DehuHyst

 

Dehumidification Hysterisys 
Default is 

5 % RH

 

Conditional parameter to Humidity models VTR735xX5x00(X)

 

Humidity control hysterisys. Used only if dehumidification sequence is enabled: 

 

Range is: 

2 to 20% RH

 

DehuCool

 

Maximum Dehumidification 
Cooling output 
Default is 

100 %  

Conditional parameter to Humidity models VTR735xX5x00(X)

 

Maximum cooling valve position when dehumidification is enabled. This can be 
used to balance smaller reheat loads installed in regards to the capacity of the 
cooling coil. 
Range is: 

20 to 100 %

 

St-By TM 

Stand-by Timer value 
Default 

0.5 hours

 

Time delay between the moment where the PIR cover detected the last movement 
in the area and the time which the Terminal Equipment Controller stand-by mode 
and setpoints become active.  
Range is: 

0.5 to 24.0 hours

 in 0.5hr increments 

Unocc TM 

Unoccupied Timer value 
Default 

0.0 hours

 

Time delay between the moment where the Terminal Equipment Controller toggles 
to stand-by mode and the time which the Terminal Equipment Controller 
unoccupied mode and setpoints become active. 
The factory value or 

0.0 hours:

 Setting this parameter to its default value of 0.0 

hours disables the unoccupied timer. This prevents the Terminal Equipment 
Controller to drift from stand-by mode to unoccupied mode when PIR functions are 
used 
Range is: 

0.0 to 24.0 hours

 in 0.5hr increments 

St-By HT

  

Stand-by heating setpoint 
Default value = 

 69 °F

 

The value of this parameter should reside between the occupied and unoccupied 
heating setpoints and make sure that the difference between the stand-by and 
occupied value can be recovered in a timely fashion when movement is detected 
in the zone.  
Stand-by heating setpoint range is: 

40 to 90 °F ( 4.5 to 32.0 °C )

 

St-By CL

  

Stand-by cooling setpoint limit 
Default value = 

78 °F

 

The value of this parameter should reside between the occupied and unoccupied 
cooling setpoints and make sure that the difference between the stand-by and 
occupied value can be recovered in a timely fashion when movement is detected 
in the zone.  
Stand-by cooling setpoint range is: 

54 to 100 °F ( 12.0 to 37.5 °C )

 

Unocc HT

  

Unoccupied heating setpoint 
Default value = 

 62 °F

 

Unoccupied heating setpoint range is:  

40 to 90 °F ( 4.5 to 32.0 °C ) 

Unocc CL

  

Unoccupied cooling setpoint limit 
Default value = 

80 °F

 

Unoccupied cooling setpoint range is:  

54 to 100 °F ( 12.0 to 37.5 °C )

 

heat max

 

Maximum heating setpoint limit 
Default value = 

90 °F ( 32 °C )

 

Maximum occupied & unoccupied heating setpoint adjustment.  
Heating setpoint range is:  

40 to 90 °F ( 4.5 to 32.0 °C ) 

cool min

 

Minimum cooling setpoint limit 
Default value = 

54 °F ( 12 °C )

 

Minimum occupied & unoccupied cooling setpoint adjustment.  
Cooling setpoint range is:  

54 to 100 °F ( 12.0 to 37.5 °C )
