Digital display thermostat ATED330A
Panel operation:
1, Control temperature (shutdown temperature) adjustment: Press the set key to display the control temperature, Press the Digital display thermostat ATED330Aor Digital display thermostat ATED330Akey to change the value and remember. Hold down theDigital display thermostat ATED330A keys and Digital display thermostat ATED330A keys for more than seconds to quickly increase or decrease the value. Press the set key to exit the adjustment status display cabinet temperature​; If you do not press any key​, After six seconds to restore the display cabinet temperature. (Control temperature adjustment range: parameter E1 ~ parameters E2) ​
2, Refrigeration indicator light​ : During refrigeration process, the cooling light is bright ; Under constant temperature state, cooling light off ; During the delay, the chunk lamp flashes​ .
3, Heating indicator light ​: Heating process, the heating light is bright ; Under constant temperature state, heating light off ; During the delay, the heating lamp flashes .
4, Parameter setting:
​ • Press the set key for six seconds​, Enter the parameter settings, while flashing display E1;
• Then press the set key to change the parameter selection,​ In order E2,E3,E4,E5,C1,C2,P1,P2,P3, E1;
​ • Press Digital display thermostat ATED330A​ orDigital display thermostat ATED330A key , Can display the value of the parameter and modify, store data;
• Within six seconds no longer press any key to return to normal mode of operation.​

5, Restore factory settings: Press and hold the Digital display thermostat ATED330A​ key for one second, and then press & hold the Digital display thermostat ATED330A key for another six seconds, the display flashes. At this point all parameters to restore the factory value, After six seconds to return to normal mode of operation.
6, Parameter lock​: Press the Digital display thermostat ATED330A​ key for six seconds, flashing "OFF" means lock, "ON" means unlocking​. After the parameters are locked, the parameters can only be viewed and can not be changed​. Control the temperature adjustment is still valid. (Factory setting "ON")

Function Description:
1, Cooling control​:

• When the temperature control mode (parameter C2) is set to 0, after the compressor has been delayed, When the cabinet temperature is greater than (control temperature + temperature difference), the compressor starts​ . Cabinet temperature is less than the control temperature, the compressor stops.|
•​ To protect the compressor,​ the time for the compressor to stop each time must exceed the delay time (E4 parameter), then compress can restart.
2, Heating control:
•​ Temperature control mode (parameter C2) is set to 1, the heater after a delay, when the cabinet temperature is less than (control temperature - temperature difference), the heater began to heat. Cabinet temperature is greater than the control temperature, the heater stops heating.
​3, Alarm function:
​ •​ After the initial shutdown, when the sensor temperature exceeds the P1 maximum alarm value, or less than P2 minimum alarm value, and the continuous time exceeds the alarm delay time P3, enter the alarm state.
​ •​ When the alarm indicator flashes, the alarm relay is on. Press any key to stop flashing, but still on. When the temperature returns to normal, the alarm relay is disconnected and the alarm indicator goes off.
•​ In the high temperature alarm, when the cabinet temperature is lower than (P1 maximum alarm value - alarm hysteresis P4), out of the alarm.
• In the low temperature alarm, when the cabinet temperature is higher than (P2 maximum alarm value + alarm hysteresis P4), out of the alarm.
• Connected to the power supply after two seconds, when the library temperature in a constant temperature state, the direct start of the alarm without the need for the initial shutdown.
•​ When adjusting the alarm parameter value, the high temperature alarm value (P1 parameter) must be greater than the low temperature alarm value (P2 parameter) .
4, Abnormal mode of operation:
Cabinet temperature probe short circuit or high temperature limit (greater than 120 ℃ 248 ℉) show "HH" ; Cabinet temperature probe open or low temperature limit (less than - ℃ - ℉) show "LL". The alarm light flashes .

Installation precautions:
1, To prevent high frequency interference, the probe line can not be bundled with the power line or control line parallel, to separate wiring.
2, Such as installation needs, can extend the probe line up to 100 meters, no need to re-check.
3, The thermostat can not be installed in a dripping place.
