TB7300 SERIES COMMUNICATING FAN COIL THERMOSTATS
62-2018—05
20
Aux cont
Auxiliary contact function and
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 and Fan On = Contact Closed/
Unoccupied and Fan On or Off = Contact Opened
4
Auxiliary NC
, Occ or St-By and Fan On = Contact Opened/
Unoccupied and 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 and 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
Floating actuator timing
Default value =
1.5 minutes
For floating models TB73xxC5x14(x) only
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
Default value =
4 cph
For on/off models and sequences TB73xxC5x14(x) only
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 cph will represent a higher accuracy of control at
the expense of wearing mechanical components faster.
Range is:
3, 4, 5, 6,7 and 8 cph
RA/DA
Reverse acting or Direct acting
signal
Default value =
DA signal
For analog models TB73xxF5x14(x) only
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
Reheat
Sets the reheat output time
base
Default value =
0 = 15 minute
Valid only if reheat sequences are enabled
0 =
15 minutes
1 =
10 seconds for Solid state relays
UI3 dis
Display UI3 value.
Used as diagnostic/service help to troubleshoot and diagnose
sensor operation.
Supply or change over temperature when UI3 is configured as an
analog input .
