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 over 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.

Overview

What is ITC-306T?
ITC-306T is a pre-wired heating output temperature controller with time function specifically for breeding and planting. It can be set to two different temperatures with its function of dual time cycle setting during 24 hours according to the day and night, which can more suitable for the physiological needs of animals and plants. ITC-306T can be widely use in over-heat protection and automatic temperature control system of all sorts of electrical equipment for aquarium, pets breeding, hatching, fungus fermenting, and seed germination accelerating, etc. This plug and play product is designed with dual LCD display, and offers the optional display of Centigrade or Fahrenheit, which makes it more humanized temperature control.

Key Operation Instruction

How to set parameters
When the controller is working normally, press “SET” key for over 3 seconds to enter parameters set up mode. “SET” indicator light will be on. PV window displays the first menu code “TS1” ‘, while SV window displays according setting value. Press “SET” key to go to next menu and display according menu code, press “” key or “” key to set current parameter value. After setting done, press “SET” key for 3 seconds at any time to save the parameters change and return to normal temperature display mode. During setting, if there is no operation for 10 seconds, the system will quit setting mode and return to normal temperature display mode without saving the parameters change.

Temperature Control Range Setting (TS, DS)
When the controller is working normally, PV window displays current measured temperature, as well as SV window displays temperature setting value. When the measured
temperature PVSTS (temperature set value)-DS (heating differential value), system enter heating status, the WORK1 indicator light will be on, and heating relay starts to work; when the measured temperature PV≥ TS (temperature setting), the WORK1 indicator light will be off, and heating relay will stop working. For example, set TS=25°C, DS=3°C, when measured temperature is lower or equal to 22°C (TS-DS) , system enters heating status; when the temperature raised to 25°C(TS), stop heating.

Cycle Time Setting (TR, TAH, TAM,TBH, TBM, стн, стм)
When TR = 0, time setting function is off, and there are not parameters TAH, TAM, TBH, TBM, CTH, CTM showing in the menu.
When TR=1, time setting function is on.
Time A~ Time B~ Time A is a cycle, 24 hours.
During Time A~ Time B, the controller runs as TS1 and DS1 setting; during Time B ~ Time A, the controller runs as TS2 and DS2 setting;
e.g. Set as TS1=25, DS1=2, TS2=18, DS2=1; TR=1, TAH=8, TAM=30, ТBH=18, TBM=0, CTH=9, CТM=26
During 8:30-18:00 (Time A~ Time B), the temperature controls between 23°C~25°C(TS1 – DS1~TS1); During 18:00 to the next morning 8:30 (Time B~ Time A), the temperature controls between 17°C~18°C(TS2-DS2~TS2); Parameter CTH and CTM are used for current time setting. The setting time is 9:26.

Temperature Calibration (CA)
When there is deviation between measured temperature and actual temperature, use temperature calibration function to align the measured temperature and actual temperature. The corrected temperature is equal to temperature before calibration plus corrected value (corrected value could be positive value, 0 or negative value).

Display in Fahrenheit or Centigrade unit (CF)
Users can select display with Fahrenheit or Centigrade temperature value according to their own habit. Default setting is display with Centigrade temperature value. For displaying with Fahrenheit temperature value, set CF value as F.

ATTENTION: when CF value changed, all the setting value will be recovered to factory settings.

Error Description

Sensor Fault Alarm: when temperature sensor is in short circuit or open loop, the controller will initiate sensor fault mode, and cancel all the actions. The buzzer will alarm, LED displays ER. Buzzer alarm could be dismissed by pressing any key. After faults solved, the system will return to normal working mode.

Over-temperature Alarm: when measured temperature exceeds the measuring range (less than -50°C /-58° F or higher than 99 °C/210 ° F), the controller will initiate over- temperature alarm mode, and cancel all the actions. The buzzer will alarm, LED displays HL. Buzzer alarm could be dismissed by pressing any key. When temperature returns to measuring range, the system will return to normal working status.

TE error
When setting TR=1 and if it is power-on again after power off, the “beep – beep” alarm in 0.5Hz frequency of the buzzer. The temperature controlled by the standard of TS1 while PV window displaying the current temperature and the window of SV displaying TE error. At this time, Press any keys can stop the alarm. When enter to the setting menu, it will jump to TH code directly, then you can set present time (TH, TM) easily and quit into normal working status.

Troubleshooting Guide

Issues	Causes	Solutions
The probe reading is incorrect.	The probe is placed in a area with poor temperature circulation. The probe is damaged.	Adjust the position of the probe. If the probe was used in liquids, dry it using a hairdryer and then test it at room temperature. Check if the probe is intact. If the deviation is small, use the CA function to calibrate.
Heating output will not turn on.	Incorrect settings. Incompatible heater. Output malfunction.	Verify that the settings are correct. The heater power is within the range of 100-240V, 10A. The heater can automatically turn on when plugged in. The heater does not have a built-in temperature control, or the built-in temperature control does not affect the ITC-306T control. There is no problem with 1&2，please: Unplug the controller. Press and hold the ‘SET’ button. Plug the controller to power on, then release the ‘SET’ button Quickly press the ‘ ‘ button ( do not press the ‘ ‘ button). The ‘work1’ indicator and output should activate. If the heater still does not work, please contact customer service.
Heating output will not turn off.	Incorrect settings. Heater power exceeds limit. Output malfunction.	Verify that the settings are correct. The heater power is within the range of 100-240V, 10A. There is no problem with 1&2， please: Unplug the controller. Press and hold the ‘SET’ button. Plug the controller to power on, then release the ‘SET’ button Quickly press the ‘ ’ button (do not press the ‘ ‘ button). If the heater still does not off, please contact customer service.
