CI856/3BSE026055R1 ABB DCS programmable communication unit

Description

CI856 now has a growing number of users installing central air conditioners. Many businesses have increased their promotion efforts to the temperature controller of central air conditioners. Those who are not experts are easily induced by the poor quality temperature control of the “low price discount”. Some readers also asked us why some temperature controllers of more than 20 and 30 central air conditioners are so cheap? What is the difference in material selection compared with those 40 to 50 central air-conditioning temperature controllers on the market?

In this regard, we specially checked the relevant data, and the high-quality CI856 central air-conditioning temperature controller and the low-quality central air-conditioning temperature controller are mainly reflected in the following aspects:
1. Many cheap CI856 central air-conditioning temperature controllers use low-quality electronic components. The prices of different electronic components are far different, and the quality is also far different. Good temperature controllers use well-known brand packaging chips. The advantages of this chip are strong anti-interference and long life. But the inferior temperature controller can not be made, so it is easy to be damaged and has poor anti-static ability.
2. Select low-quality panel materials, and some manufacturers even use recycled electronic materials to process the panel of temperature controller.
3. Low quality liquid crystal temperature controller glass mirror is selected. Different viewing angles of the liquid crystal temperature controller glass mirror will also cause large cost differences.
4. In terms of production process cost reduction, some small manufacturers adopt manual welding to reduce process cost, which may lead to unsaturated solder joints, lack of welding, missing welding, and excessive welding, with high error rate.
5. Reduce labor costs. Generally, manufacturers of low price and low-quality thermostats lack professional R&D personnel and after-sales personnel, and only rely on family workshop production to make profits.
