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

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

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
