Safety Precautions

Ensure the product using within the specification.
Do not touch the terminals at least while power is being supplied. Doing so may occasionally result in injury due to electric shock.
Do not allow pieces of metal, wire clippings, or fine metallic shaving or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.
Do not use the product where subject to flammable or explosive gas. Otherwise, injury from explosion may occasionally occur.
Never disassemble, modify or repair the product or touch any of the internal parts. Electric Shock, fire, or malfunction may occasionally occur.
If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switch conditions.

Dimension and Installing

Size Diagram (Unit: mm)

Insert the temperature controller into the hole in the panel, put the adapter from the back and push it to button and make it clasp for temporarily fastening. Be sure there is no gap among the controller, panel and the adapter and then fasten the two screws on the adapter with the torque of 0.29N to 0.39N.
Be sure the ambient temperature is within the stated working range in the manual, especially when there are two or more temperature controllers installed.

Wiring Diagram

Power Connection: #9 and #10 terminals are for power connecting, which its supply voltage should be match the item model.
Platinum Resistance Sensor Connection:
Three wires sensor: connected the #3 terminal with the red wire, the other two bule wires should be separately connected to the #4 and #5 terminals.
And the sensor with two wires (e.g. PT100) should be separately connected to the #3 and #5 terminals, the #4 and #5 terminals must be connected with the wire.
Thermocouple Connection(e.g. K sensor): #3 terminal is connected to the positive pole(Red) and the #4 terminal is connected to the negative pole(Blue).

Description

The Inkbird ITC-106 is a compact and robust temperature controller that features a user-friendly LCD display with a backlight, making it easy to read and operate even in low-light conditions. The device supports a wide range of temperature sensors, including thermocouples and thermistors, ensuring flexibility in different applications. It has dual relay outputs, allowing for both heating and cooling control, which is essential for maintaining stable temperatures in various environments.

The controller also includes alarm functions to alert users of high or low temperatures, sensor failures, and power failures, ensuring that any issues are quickly identified and addressed. Its compact design and DIN rail mounting option make it easy to integrate into existing systems.

Setting Parameters

Sensor Type and Measuring Range

Remarks:

The faulty input sensor is the "K" type.
If select the wrong input sensor, the measuring temperature will be incorrect and may exceed the measuring range with displaying "orAL", control output off.

Operation Guide

Boot screen display

Enter the settings menu
Under measuring and controlling condition, press ▲/▼ to set the temperature value, press and hold the "SET" button for 2 seconds to enter into the parameters settings mode.

Sensor Input Type Setting:
Set the sensor input type as required(the faulty is the "K" type), the temperature need to calibrated for there will be deviation due to the sensor and the operating environment.

Output Parameters Setting:
The recommended control mode for the first use is the PID control(default settings of PID control), please select the self-tuning mode when the controlling temperature cannot reach the desired value after it worked over time with the stable controlled temperature.

Under the self-tuning mode, the temperature will exceed the set value and activate the alarm. The exceeding temperature value is related to the heating system but it will return to normal after finished the self-tuning. If the temperature control requirement is undemanding, please select the ON/OFF control mode which its range of temperature controlling is depended on the dF(hysteresis).

As below is the setting and the calculation:

The low temperature point=SV setting value-dF
The high-temperature point=SV setting value+dF.

dF(hysteresis) can be worked both on alarm setting and ON/OFF control mode.

PID Parameters Setting:

SSR control output: the control period(CtrL) can be set within 4 seconds(default 2 seconds);
Relay control output: The control period (CtrL) should be set to longer time(the normal is 18s) that would prolong the work life of the relay.
