C or F

 

Sets scale of the Terminal 
Equipment Controller 
Default value = 

°F 

 

°F

 for Fahrenheit scale 

 

°C

 for Celsius scale 

On hotel models, this sets the default value when the Terminal Equipment 
Controller powers up 

%RH disp

 

Local %RH Display 

 
Default value = 

OFF 

Models with Humidity sensor only 

Conditional parameter to Humidity models VTR735xX5x00(X)

 

Enables the display of humidity below the room temperature on the display 

 

 

ON

 = Display %RH 

 

OFF

 = No display of %RH

PulsedHt 

Enable pulsed electric heat 
Default Value

 

=

 Off

 

Enables Vdc modulating pulsed electric reheat applications used with SSR’s. 
Only used with VC340xX Relay Pack models 

 

 

Off 

= Regular On-Off control for VC350xE models 

Can be used with 2 pipes & 4 pipes applications 

 

On 

=  10 second pulsed time base modulation for VC340xE models 

Can only be used with 2 pipes 
The VC3400E & VC3404E cannot be used for 4 pipes applications 

Pipe No 

System type installation 
Number of pipes 
Default is: 

4.0 

Pipes 

Defines the type of system installed 

 

2.0 

Pipes

will limit the number of sequences of operation available

 

from 0 to 2

 

Will enable heat/cool operation from the same output 

 

4.0

 Pipes, can access all the sequences of operation from 0 to 4 

Will enable heat/cool operation from different output  

SeqOpera

 Sequence of operation 

Default is: 

Sequence #1

 

Selects the initial sequence of operation required by the installation type and the 
application 

 

System = 2 Pipes

For 2 Pipe output applications, the system access is also limited if RUI 1 is 
configured for local changeover COS, COC/NC or COC/NC. The current water 
temperature detected by the RUI 1 then limits the system mode available for the 
local configuration or network write. 

For sequence 2 & 3, set PulsedHt to On to enable pulsed electric reheat 
applications with VR7300B & E  

Fan Menu

 

Mode button menu configuration 
Default is: 

Menu #4

 

Menu presented are dependent on model used and sequence of operation 
selected 
Auto Mode operation for sequences 2 and 3 is dependent on Auto Fan parameter  

0 = Low-Med-High 

3

 Speed configuration using 3 fan relays ( L-M-H ) 

1 = Low-High 

2

 Speed configuration using 2 fan relays ( L-H ) 

2 = Low-Med-High-Auto 

3

 Speed configuration with Auto fan speed mode using 3 fan relays ( L-M-H ) 

3 = Low-High-Auto 

2

 Speed configuration with Auto fan speed mode using 2 fan relays ( L-H ) 

4 = On-Auto 

Single

 Speed configuration. Auto is for Fan on demand / On is On all the time
