Between Fahrenheit and Celsius can change into each other
0.1/1 control resolution switching function
This is a two-way temperature controller,If the temperature is below the lower limit, control the heating start automatically; if the temperature is higher than the upper limit control, automatic start refrigeration.
Controlling the temperature at -50 DEG C to 110 DEG C /-58 Fahrenheit Fahrenheit -230,

Many people asked the quality problems of products, I put the photos posted product movement now, let us have a good understanding of our quality, but also eliminate all doubts.
1, we can see that there are two same CPU our products, this is a strong guarantee, reliable operation. More than 90% thermostats in the market is a single chip.
2, our relay is Taiwan GOODSKY or OEG, which is in the relay industry well-known brands in the industry, other companies with domestic brands more Songle and Acer, friends can understand the electronic apart compare. This device is a device is the key, because the control of the whole of the thermostat results it is through this device in response to it, the quality of which directly determines your thermostat for how long, but now most people are in it to cut corners, because this is not a thing almost can not be used to buy back, like to use a time to reflect, but then you have confirm receipt, but also gave praise, there are Everfount people continue to be fooled. We inside is a 10A relay, but we tell you the biggest 5A application, because the relay is not full load. For that, life will be shortened, if installed inside the 5A relay, tell the user can use the 5A maximum, it is extremely irresponsible. Resistance load is the maximum current of 70% 50%. maximum current, inductive load
3, our transformer (that is red) is pouring, potting transformer benefits are not afraid of the vibration, heat is very low
4, the majority of components using SMT machine patch, sophisticated technology, this is a guarantee of quality, high reliability than manual welding.
5, many of my friends will ask why there are so empty elements, that is reserved for the WH7016E or WH7016H functions with more models, design can reduce the pressure on the stock and cost control of the enterprise effectively the compatible platform design is equivalent to the car.
What is good, we used to know, we are very focused on product durability and practicability, a lot of things will not sell go bad, it is very rare, unless the quality is very bad, but for a period of time bad very common, so we welcome old users in the use of later comments,
How to choose the correct thermostat:
1: choose the correct temperature range: we have -50-110 degrees, -9.9-99.9 degrees, -30-300 degrees range
2: selection of one-way or two-way control, control, control of heating or cooling is called a one-way control load, at the same time to control the heating and cooling load is a two-way control,
3: of control power, some of our models have 10A and 30A two optional relay 10A relay, with maximum load 1000W, 30A relay can be connected with a maximum load of 2000W, please, the external AC contactor exceeds the maximum power control of the thermostat
4: to control the resolution (i.e. temperature step), to be accurate to 1 degrees or 0.1 degrees.
Choose the correct 5: supply voltage.
Choose the type of probe to 6:
The metal probe for measuring air and non corrosive liquid. Is characterized by fast response.
Plastic probe is suitable for measuring seawater is corrosive liquid, slow corrosion.
Screw probe for mass production equipment installation.
4 point probe is the probe for water pipes.
We support the thermometer probe line extension, the maximum length to 100 meters. The common line can be. Note: the probe line and the power line not long distance parallel line long distance parallel lines need to go as far as possible the use of dual core shielded cable, two wires inside the probe, the outer shield grounding network.
A brief description of the various types of:
WH7016C:-50-110 of one-way control, control the resolution of 1 degrees, with over temperature alarm output
WH7016D:-30-300 of one-way control, control the resolution of 1 degrees, with over temperature alarm output
WH7016E:-9.9-99.9 degree one-way control, control resolution of 0.1 degrees, with overtemperature alarm output
WH7016G:-50-110 degree one-way control, control resolution of 1 degrees, with overtemperature alarm output
WH7016J:-30-300 degree one-way control, control resolution of 1 degrees, with overtemperature alarm output
WH7016H:-50-110 degree bidirectional control, control resolution of 1 degrees, with overtemperature alarm output
WH7016S:-9.9-99.9 degree bidirectional control, control resolution of 0.1 degrees, with overtemperature alarm output
WH7016K:-50-110 degree bidirectional control, control resolution of 1 degrees, with overtemperature alarm output, semiconductor refrigeration chip dedicated
WH7016R:-9.9-99.9 degree bidirectional control, control resolution of 0.1 degrees, with overtemperature alarm output, semiconductor refrigeration chip dedicated
