A
TRAC2.1 pot 1 (NSB). The discharge sensor is locked off at night and control is from the room
sensor/set-point only.
NOTE:
The room sensor must be present for this option to operate. (It also requires that
dipswitch 3 is on for night setback to operate.)
If there is a call for heat at night the discharge sensor will act as a discharge air modulating high limit.
This is not field adjustable and will vary between 120 and 150F. Due to heat lag at the sensor it may
be possible that the control high limit may cycle the heater on and off.

TE 6100-960 Set-Point Controller Connections

When using the numbers TE 6100 and TE 6000 note that they are a Johnson Controls part number.
There are controls from other suppliers with different part numbers that may be substituted. The values
must be equivalent to the Johnson line.
The TE 6100-960 can be used for two functions. The first is as a discharge temperature set point, for
which it will be wired to terminals "M, S", and "U". The second use is to reset the discharge temperature
from either space or outdoor ambient temperatures. In this application it will be wired to terminals "V, Z,
X" and "Y". Refer to the unit-wiring diagram to determine the usage of any TE 6100-960.
A discharge set-point knob on the front of the C-TRAC2.1 is usually used as the set point. If it is in use
the C-TRAC2.1 terminals "S" and "SP" will have a jumper across them.
NOTE:
If a TE 6100-960 is being used as a remote discharge set-point, the "S" and "SP"
terminals on the C-TRAC2.1 will not be jumpered.
Option 1 – Combination Sensor/Set-Point
If the TE 6100-960 is being used as a room reset device it is usually used as a combination sensor/set-
point.

Option 2 – Remote Discharge Set-Point with Separate Discharge Sensor
Although two separate controls can be employed (one as the sensor in the space and one as a reset set point
located in a room where it cannot be tampered with).
