For 2 Pipe output applications, the system access is
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

configuration
Default is: Menu #4
Menu displayed 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-A )
3 = Low-High-Auto
2 Speed configuration with Auto fan speed mode using
2 fan relays ( L-H-A )
4 = On-Auto
Single Speed configuration. Auto is for Fan on demand /
On is On all the time

Dehumidification lockout
Default value:
On = Authorized Conditional parameter to Humidity models
VT735xX5x00(X)
Typically toggled via 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
VT735xX5x00(X)
Used only if dehumidification sequence is enabled:
Range is: 30-95% RH
