Overview

What can the DT10 do?
This is a dual relay output temperature controller which can be used as over- temperature protection and automatic temperature control system for electrical appliances for home-brew, aquarium, pet breeding, incubation, seedling heat mat, oven, terrestrial heat pad/lamp, heating pump, home fermentation, electric radiator, electric oven etc.
The temperature controller is equipped with a dual relay to connect with both refrigeration and heating equipment to get the desired temperature. The dual LED displays and offers display switch between Centigrade and Fahrenheit. With its 1800 watt capacity, can handle most any 120 volt appliance.
The DT10 is designed with compressor delay protection for refrigeration, high and low temperature alarm and sensor fault alarm. Functions such as temperature calibration, separately set differential for refrigeration and heating, enable more accurate temperature control.

Key Operation Instructions

Enquiry Set Point
When the controller is working, short press the “UP” key for one time, the heating differential (HD) will be displayed; short press the “ DOWN ” key for one time, then the cooling differential (CD) will be displayed. The screen will return to normal display mode after 2 seconds without any operate.

How to Set Parameters
When the controller is working normally, press “SET” key for over 3 seconds to enter into parameters set up mode. “SET” indicator will be on. PV window displays the first menu code “TS”, while SV window displays according setting value. Press “SET” key to go to next menu and display according menu code, press “UP” key or “DOWN” 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, HD, CD)
When the controller is working normally, the LED displays current measured temperature (PV), and will automatically identify and switch between refrigeration and heating working modes. When the measured temperature PV ≥ TS (temperature you set) + CD (cooling differential value), system enters refrigeration status, the cool indicator will be on, and refrigeration relay starts to work; when the cool indicator is flickering, it means the refrigeration equipment is under compressor delay protection status. When the measured temperature PV≤TS (temperature set value), the cool indicator will be off, and the refrigeration relay stops working. When the measured temperature PV≤TS (temperature set value)-HD (heating differential value), system enter heating status, the heat indicator will be on and heating relay starts to work; when the measured temperature PV≥ TS (temperature setting), the heat indicator will be off, then heating relay stops working. For example, if set TS=75°F, CD=2°F and HD=3°F, then when measured temperature is higher than or equal to 77°F （ TS+CD), system enters refrigeration status; when temperature decline to 75°F (TS), stop refrigeration; when measured temperature is lower or equal to 72°F（TS-HD), system enters heating status; when the temperature raised to 75°F (TS), stop heating. Repeat that so as to get the desired temperature range we want.
In case the time interval between two refrigeration is less than PT, please refer to 5.3.

Alarm High/Low Limit Setting (AH, AL)
When the measured temperature is higher or equal to AH, the high-temperature alarm will be triggered, the buzzer will alarm with tone “bi-bi-Biii” until the temperature is lower than AH or any key is pressed. When measured temperature is lower or equal to AL, low-temperature alarm will be triggered, the buzzer will alarm with tone “bi-bi-Biii” until the temperature >AL or any key is pressed.

Compressor Delay (PT)
Under refrigeration mode, after power on, if the measured temperature is higher than set temperature (TS) plus cooling differential (CD), the equipment won’t start refrigeration immediately but waiting for a delay time.
When the time interval between two refrigeration operations is larger than preset delay, the equipment will start refrigeration immediately; when the time interval between two refrigeration is less than preset delay, the equipment won’t start refrigeration until the preset delay is satisfied. Delay time will be calculated right after the moment the refrigeration stops.

Temperature Calibration (CA)
If there is a deviation between measured temperature and actual temperature, use temperature calibration function to align the measured temperature and actual temperature.

Display in Fahrenheit or Centigrade unit (CF)
Customers can set the temperature display in Fahrenheit or Centigrade according to their own habit. Default display is in Centigrade temperature. To display in Fahrenheit, 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 the temperature sensor is in a 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 the faults are solved, the system will return to normal working mode. Over-temperature Alarm: when the 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. The buzzer alarm could be dismissed by pressing any key. When the temperature returns to measuring range, the system will return to normal working status.
