deadband
Minimum deadband
Default value = 2.0 °F ( 1.0 °C )

Minimum deadband value between the heating and cooling setpoints. If modified,
it will be applied only when any of the setpoints are modified.
Range is: 2, 3, 4 or 5 °F, 1.0 °F increments ( 1.0 to 2.5 °C, 0.5 °C increments )

cal RS
Room temperature sensor
calibration
Default value = 0.0 °F or °C

Offset that can be added/subtracted to actual displayed room temperature
Range is: ± 5.0 °F, 1.0 °F increments ( ± 2.5 °C, 0.5 °C increments )

cal RH
Humidity sensor calibration
Default value = 0 %RH

Offset that can be added/subtracted to actual displayed humidity by ± 15.0 %RH.
Range is : ± 15.0 %RH

aux cont
Auxiliary contact function &
configuration

Default value = 0 Not Used

0 Aux contact function used for reheat
IF SEQUENCE IS SET TO REHEAT THROUGH NETWORK OR LOCAL, Ignore
this parameter

The output will directly follow the occupancy of the thermostat
1
Auxiliary NO, Occ or St-By = Contact Closed / Unoccupied = Contact Opened
2 Auxiliary NC, Occ or St-By = Contact Opened / Unoccupied = Contact Closed

Output to follow directly main occupancy and Fan on command
Typically used for 2 position fresh air damper applications.
3 Auxiliary NO, Occ or St-By & Fan On = Contact Closed / Unoccupied & Fan On
or Off = Contact Opened
4 Auxiliary NC, Occ or St-By & Fan On = Contact Opened / Unoccupied & Fan
On or Off = Contact Closed

Output to follow secondary network occupancy command

5 Auxiliary On/Off Control through auxiliary network command. The output can
be commanded through the network for any required auxiliary functions through a
separate & dedicated network variable.

Auto Fan
Auto Fan Function
Default value: AS

Auto Speed Fan Mode operation for Fan Sequences 2 and 3

AS = Auto Speed during occupied periods. Fan is always on during occupied
periods.
AS AD = Auto Speed / Auto Demand during occupied periods.

FL time
For floating models
VT73xxC5x00(x) only
Default value: 1.5 minutes

Floating actuator timing
Maximum stroke time of floating valve actuator.

Range is: 0.5 to 9.0 minutes in 0.5 minutes increment

cph
On/Off devices cycles per hour
For On/Off models & sequences
VT73xxC5x00(x) only
Default value = 4 C.P.H.

Will set the maximum number cycles per hour under normal control operation. It
represents the maximum number of cycles that the equipment will turn ON and
OFF in one hour.
Note that a higher C.P.H will represent a higher accuracy of control at the expense
of wearing mechanical components faster.
Range is: 3, 4, 5, 6,7 & 8 C.P.H.

RA/DA
For Analog models
VT73xxF5x00(x) only
Default value: DA signal

Reverse acting or Direct acting signal for Analog output signals
DA = Direct acting, 0 to 100 % = 0 to 10 Vdc
RA = Reverse acting, 0 to 100 % = 10 to 0 Vdc

Reheat
Default value: 0 = 15 minute

Sets the reheat output time base
Valid only if reheat sequences are enabled
0 = 15 minutes
1 =
10 seconds for Solid state relays

UI3 dis
Display UI3 value.

Used as diagnostic / service help to troubleshoot and diagnose sensor operation
Supply or change over temperature when UI3 is configured as an analog input
( SS or COS )
