Model 1801-KEYS Digital Thermostat Module Model XH-W1801-2

The main significance of the character display.

S0: the code for setting temperature control value,
What is “temperature control value”: the desired temperature which you want to control.

Sc:the code for temperature sensor correction,
Temperature sensor correction: When you believe that the controlling system(including sensor) happen errors and the
result couldn`t be consistent with value which is tested by more accurate grade measuring device, then you can use this
“correction” function in order to obtain consistent result.Cause to use the function, to avoid precisely meter the
inverse modified inaccurate. Set an error in the direction opposite the range -5.0 to 5.0 the same value. If high 3.0,
then set -3.0; if low 3.0, then set 3.0.

Po: the symbol for hysteresis

Hysteresis value: in pure level digital control, there must be a proper return difference (also known as poor or dead
zone switch), if the hysteresis is too small, result in frequent exchanges and contacts and reduce the service life;If
the hysteresis too big,will cause the environmental of controlled range fluctuates too big. In some cases (such as air
conditioning room temperature control), can be used to set hysteresis to let the controlled value fluctuates in a
setting rang, to avoid waste. In general,it is appropriate to set hysteresis with 0.3% of full scale.

cc: cooling / heating switch

cc = 0 means the cooling mode, when the actual temperature is higher than the controlled temperature, then the cooling
equipment is turned on

cc = 1 means the heating mode, when the actual temperature is below the controlled temperature,then the heating
equipment is turned on

Instructions
Long time to press the SET key to enter the parameter setting menu, set the following:
Temperature control settings “SO”, by setting the plus and minus to set value, and then press the SET key to complete
the set (setting range 0-99)

Setting hysteresis “PO”, by setting the plus and minus to set value, and then press the SET key to complete the set
(setting range 1-20)

Work mode setting “CC”, by setting plus and minus settings to set, and then press the SET key to complete the set (“1”
heating / “0” cooling)
Finally shows “—“.it indicates complete all settings

Setting Examples
1, set 50℃ degrees to power on, 45℃ to power off
Set cooling mode CC = 0; control 50, that means SO = 50, hysteresis is set to 5, that means PO = 5;

2, set 45℃ power on, 50℃ power off
Set heating mode CC = 1; control 45, that means SO = 45, hysteresis is set to 5, that means PO = 5;

If display “HHH”, please check if the sensor input is shorted or exceeds the limit;

If display “LLL”, the sensor maybe short circuit or exceeds the limit, then it automatically starts protection function, will cut off the power to the load,it require you to slove the trouble before re-use

General knowledge on “ThermoElectric Module”

ThermoElectric-Module-principleWorking principle of ThermoElectric Module

Thermoelectric cooling thermoelectric effect is the Peltier effect is mainly used in refrigeration technology. Practical thermoelectric cooling device is more significant by the thermoelectric effect, more efficient thermoelectric cooling semiconductor thermocouple composition.

The semiconductor thermocouple and an N-type semiconductor P-type semiconductor. N-type material has excess electrons have a negative thermoelectric power. P-type material electron deficiency, there are thermoelectric power; when the electrons pass through the junction from the P-type to N-type, the energy will increase, and the increase of energy equivalent to the energy consumed by the node. It can be used to reduce the temperature difference to prove.

On the contrary, when the electron current from the N-type to P-type material, junction temperature will rise. Direct contact of the thermocouple circuitry in the actual reference is not available, so the connection method instead of the graph, experiments show that the introduction of a third material (copper plate and connecting wires) does not change in the temperature difference between the circuit characteristics of the circuit.

Thus, the semiconductor element can be connected to a variety of different methods to meet the requirements of users. Put a P-type semiconductor and a link to the N-type semiconductor thermocouple, after connecting the DC power supply, will result in the joints and heat transfer temperature difference.
In the joints, the direction of current is above N to P, the temperature drops and absorbs heat, which is the cold end. And in a joint below, to the current direction is P N, and the exothermic temperature rises, therefore the hot end.

According to the figure of the plurality of semiconductor thermocouples connected in series on the circuit together, and in terms of heat transfer is in parallel, which constitute a common refrigeration thermopile. Press the icon connected to a DC power supply, the above is a thermopile cold side, here is the hot end. With a variety of heat exchangers and other heat transfer means, so that the hot end of the thermopile continues to heat and maintain a certain temperature, the cold junction of the thermopile into the work environment to the endothermic cooling, which is the working principle of thermoelectric cooling.

Note the use of refrigeration piece

1. I do not know when the cold surface of the refrigerator, we can use this method, the positive power supply red and black wire to negative, and in the absence of thermal conditions, instantaneous power test, namely touch refrigeration the two ends, one side will feel the heat, one side slightly apathetic, heat one side of the hot side, the side of cold sensation. But time can not be more than 5 seconds, otherwise due to the hot end temperature is too high, can easily cause the device to burn.
2, under normal conditions, with red lead is usually expressed as positive: usually in black is negative, which is wiring methods thermoelectric cooler at work. Takes pyrogenic. As long as the current polarity can be changed. Refrigeration work must adopt switching power supply, power supply ripple factor should be less than 10%.
3, the number of ways to identify and limit the voltage, thermocouple refers to the number of P, the number of nodes N thermocouple cooler. For example: the refrigerator model is TEC1-12706, then 127 for cooling the thermocouple logarithm, 06 to allow the current value: A, cooler ≈ thermocouple voltage limit on the number × 0.12, for example: TECI- 12706 limit voltage V = 127 × 0.12 = 15.4 (V). Normal operating pressure is 78% limit voltage, such as TEC1-12706 operating voltage of 15.4 * 0.78 = 12.01V.
4, both in the use of various refrigerating machines or in the test, the temperature of the refrigerant caused by hot and cold heat exchange surface should be brought to room temperature (generally 15 minutes or more). Otherwise easily lead to damage to the refrigerator.
5, in order to prolong the life of the thermoelectric cooler, refrigeration components of four weeks to respond to seal deal. We have two kinds of methods, one is the use of silicone seal 704; another is taken epoxy sealed, sealed refrigeration purpose is to make the thermocouple is completely isolated from the outside air. Plays a moisture-proof effect, and can extend the life of the refrigerator.
6. When installing, first wipe clean both sides of refrigeration components and evenly coated with a thin layer of thermal grease were hot and cold surfaces in the refrigerator. Aluminum radiator or surface storage fins in contact with the cooler should be smooth, and wipe clean, but also the surface evenly coated with thermal grease; cooling device during the installation process and cold storage must good contact cold, hot surfaces should be fully in contact with the surface of the aluminum radiator (eg with screws, a few screws force should be uniform, not excessive or uneven force). To achieve the best cooling effect, between the cold storage insulation and aluminum radiator filling applications, its thickness is generally 25-30mm appropriate.
7, install pressure refrigeration piece recommendations between 150PSI to 300PSI, the pressure is too low will make poor contact chip cooling contact surfaces, too much pressure can damage the chip cooling.
8 users without special equipment, the qualified judge cooler or not, mainly to test its resistance. You can use the data bridge or ohmmeter, measure the resistance of the refrigerator with compensation. Refrigeration components with a multimeter to test the static resistance is not accurate, just for reference.
9, in the handling and installation process of the refrigerator, the operator should be gently strictly prohibited refrigeration piece fell from a height, even at the height of 10-20cm also cause significant internal resistance of the refrigerator changes, resulting in damage to the cooling device.
10, the semiconductor chip cooling in the following situations, their life will likely drastically cut:
A, the frequent use of alternating hot and cold use
B, lower vibration use
C, hot side heat sink temperature exceeds 65 degrees
D, the working voltage of excess pressure (recommended no more than 70% of the limit voltage)
Heating surface E, poor contact chip cooling
F, refrigeration is not sealed plastic piece around the use in wet environments
11, the semiconductor chip cooling in the following cases, there will be rapid deterioration of the possibilities:
A, fever chip cooling surface does not contact any of the ventilation objects
B, refrigeration piece using voltage exceeds the limit operating voltage
C, refrigeration piece under pressure over 500PSI
