TTC Installation Information
Wiring Diagram
The wiring diagram provides required wiring information.
12 VAC/DC @ 250 mA must be supplied to the unit’s
“power input.” Connect unit as indicated. If the unit is
powered by a step down transformer, then 24, 115 or 230
VAC must be connected to the transformer primary and
the secondary connected to the power input of the
controller/indicator.
Power and thermocouple wire should not be placed in
the same conduit or wiring trough. However, wires from
several thermocouples may be in the same conduit
or wiring trough. If shielded thermocouples are used,
the shields should be insulated electrically from the
thermocouple wires and terminated to earth ground.
Ungrounded thermocouples are required when
multiple controllers/indicators are used or if the
transformer is grounded.
Wiring Diagram―Different Power Requirement
For long thermocouple runs, the proper thermocouple
extension wire must be used, and the proper polarity
must be maintained. If these precautions are not
observed, the unit may not meet specifications.

TTC Installation Information
Assembly
1. Remove bracket and insulator from unit.
2. Place TTC unit through panel cut-out.
3. Place insulator on TTC unit and attach bracket.
NOTE: Bracket is not to touch metal surface of panel.
Bracket must rest on insulator. Any other method of
mounting will cause damage to the internal operation of
the TTC unit.

Set Point Calibration and Output States
If transformers other than those supplied by Antunes
Controls are used, the transformer colors/leads and
power capabilities may not be the same.
If field calibration is required, a two-point calibration
with a millivolt generator can be used. Allow 30 minutes
for the unit to stabilize before calibrating. Calibrate the
low reading by adjusting the zero pot. Enter the second
calibration higher than the first point and adjust the span.
Recall these two points if needed.

When the button on the lower left of the unit is pushed in
and held, the set point is displayed. As long as the button
is held in, the set point is displayed. When the button is
out, the temperature at the thermocouple is displayed.
The knob on the lower right is used to change the set
point. Turn the knob clockwise to increase the set point.
Turn the knob counter clockwise to decrease the set
point.
The diagram above shows the output states of the
controller internal relay when the temperature as seen by
the thermocouple is above or below the set point. Make
the connection accordingly observing the power rating
of the contacts. The unit will read “EEE” for over range
inputs. If the thermocouple “opens”, the internal relay will
go its “not operated” state.
Sold State Replay Output
When the temperature seen by the thermocouple
is above the set point, there will not be any voltage
between - and + terminals. If the temperature seen by the
thermocouple is below the set point, there will be 12‒16
VDC output. This output is capable of providing 30 mA.
If an “open” thermocouple condition occurs, the voltages
between - and + terminals will be zero.
