Install Instructions
30 | PIR Ready VT7300 Series-Installation Guide 
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 
Terminal Equipment Controller 
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
