China LCD Thermostat

LCD thermostat be applied in the geothermal heating system, fully embodies the floor heating system of intelligent, automated, personalized concept of consumption. Popularity in China is much higher than the United States and Europe, so diverse in our form, variety, quality is uneven.You must have   learned a lot about the advantages of LCD thermostat, and this article is no longer to be addressed in this chapter, we prefer to analyze the current situation of China's LCD thermostat, so that the selection of reference.

Early LCD thermostat: we find most manufactories directly modify the central air-conditioning coil thermostat into LCD thermostat, which exist many problems.

1.LCD interface is too large or display symbols are not commensurate with the standard.

2.Control output terminals or circuit (components) can not withstand high current.

3.External sensor (probe) cable is soft line, which can not be inserted into the embedded pipe, future maintenance is also a kind of hidden danger.

4.Control logic geothermal heating system requirements for non-conformity is not dedicated, not practical.

5.Only way temperature control circuit can not achieve the internal control outer limit. Monitoring and control room air temperature, ground temperature limit that can not be done.
