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.

FL time

Floating actuator timing

VT7200C5x00(x) 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

VT7200C5x00(x) models 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. 3, 4, 5, 6,7 & 8 C.P.H.

RA/DA

Reverse acting or Direct acting

signal for Analog output signals

VT72xxF5x00(x) 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
