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
