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
Lockout
Keypad lockout levels
Default value = 0 No lock
Level
Occupied temperature
setpoints
System mode setting Fan mode setting Unoccupied Override
0 Yes access Yes access Yes access Yes access
1 Yes access Yes access Yes access No access
2 Yes access No access No access Yes access
3 Yes access No access No access No access
4 No access No access No access Yes access
5 No access No access No access No access
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 VR7300A & C models
Can be used with 2 pipes & 4 pipes applications
On = 10 second pulsed time base modulation for VR7300B & E models
Can only be used with 2 pipes
The VR7300B & E 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
VR7300A, B C & E Models
System = 4 Pipes
VR7300A & C Models only
0 = Cooling Only Yes access Yes access
1 = Heating Only Yes access Yes access
2 =
Cooling / Heating
Cooling With Electric Reheat Yes access
Cooling With Electric Reheat
Yes access
Cooling / Heating
3 = Heating With Electric Reheat Yes access No access
4 = Electric Reheat Only Yes access No access
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
