TOccTime *
Temporary occupancy time
Default value = 2 hours
Temporary occupancy time with occupied mode setpoints when override function is enabled
When the thermostat is in unoccupied mode, function is enabled with either the menu or BI1 or
BI2 configured as remote override input. 0,1, 2, 3, 4, 5, 6, 7, 8, 9, 10, & up to 24 hours
DoorTime *
Forces Unoccupied mode if door
stays open more than:
Default value = 2 minutes
If BI 1 is configured for motion detector and occupancy sensor. If the door stays open more than
this variable on BI 2 and there is movement in the room; the zone will remain in unoccupied
mode for the Maid. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 minutes
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.
2, 3, 4 or 5 °F, 1.0 °F increments ( 1.0 to 2.5 °C, 0.5 °C increments )
cal RS
Room air temperature sensor
calibration
Default value = 0.0 °F or °C
Offset that can be added/subtracted to actual displayed room temperature
± 5.0 °F, 1.0 °F increments ( ± 2.5 °C, 0.5 °C increments )
aux cont *
Auxiliary contact function &
configuration
Default value = 0 Not Used
0 Aux contact function not used or used for reheat
IF SEQUENCE IS SET TO REHEAT THROUGH NETWORK OR LOCAL, Ignore this parameter
( Sequence 2, 3 or 5 )
The output will directly follow the occupancy of the thermostat
1 Auxiliary NO, Occupied = Contact Closed / Unoccupied = Contact Opened
2 Auxiliary NC, Occupied = Contact Opened / Unoccupied = Contact Closed
(3 & 4 are not used)
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.
FL time *
Floating actuator timing
VT72xxC10xx models only
Default value: 1.5 minutes
Maximum stroke time of floating valve actuator.
0.5 to 9.0 in 0.5 minutes increment
cph *
On/Off devices cycles per hour
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. 3, 4, 5, 6,7 & 8 C.P.H.
RA/DA *
Reverse acting or Direct acting
signal for Analog output signals
VT72xxF10xx models only
Default value: DA signal
Changes the action of the analog outputs on the analog models.
DA = Direct acting
0 to 100 % = 0 to 10 Vdc
RA = Reverse acting
0 to 10 % - 10 to 0 Vdc
Reheat *
Sets the time base for the reheat
output if used
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 supply or changeover
temperature when UI 3 is configured
as an analog input ( SS or COS )
Used as diagnostic / service help to troubleshoot and diagnose sensor operation
