1. 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.
With large power output 1200W(110V)/2200W(220V), it’s suitable for most applications.
And the temperature can be controlled more accurately with its function of temperature
calibration and temperature hysteresis.

4. Key Operation Instruction
4.1 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 lamp will 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

5.1 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 PV≤TS (temperature set value)-DS (heating differential value),
system enter heating status, the WORK1 indicator lamp will on, and heating relay starts to
work; when the measured temperature PV≥ TS (temperature setting), the WORK1
indicator lamp will 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.

5.2 Cycle Time Setting (TR, TAH, TAM,TBH, TBM, CTH, CTM)
When TR = 0, time setting function is off, and there are not parameter TAH, TAM,TBH,
TBM, CTH, CTM showing in the menu.
When TR=1, time setting function is on.
TA-TB-TA is a cycle, 24 hours.
During time TA-TB, the controller runs as TS1 and DS1 setting; during time TB-TA, the
controller runs as TS2 and DS2 setting;
During 8:00-18:00 (TA-TB), the temperature controls between 23°C~25°C(TS1-
DS1~TS1);
During 18:00 to the next morning 8:00 (TB-TA), the temperature controls between
17°C~18°C(TS2-DS2~TS2);
Parameter TH and Tm are used for current time setting. For example, if now the time is
9:26, then set TH=9, Tm=26.
5.3 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).
5.4 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.
Attentions: when CF value changed, all the setting value will be recovered to factory
settings.
6. Error Description
6.1 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.
6.2 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.

6.3 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.
