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
