Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a high-precision controlled temperature controller. Background Art

[0002] Thermostatic controllers are widely used in urban heating systems. By controlling the floor heating equipment of residential and public buildings to achieve automatic operation, they can not only save energy to the maximum extent, but also provide users with the most comfortable indoor temperature. All of this is achieved based on the precise temperature control of the thermostatic controller. A very important condition for achieving precise temperature control is that the thermostatic controller must collect high-precision indoor temperature. In actual use, the temperature sensor on the thermostatic controller will be affected by many heat sources (such as internal heat-generating power modules, wireless modules, etc., and external radiators, radiators, etc.), resulting in the collected temperature being much higher than the indoor temperature, thereby affecting the precise control of the temperature, not only failing to provide a comfortable indoor temperature, but also resulting in energy waste. Although the thermostatic controllers on the market currently use various calibration methods to reduce the temperature difference caused by the influence of the heat source, they can only reduce the error and make the collected temperature closer to the room temperature. The error control of good ones is ±1 degree, the ordinary one is ±2 degrees, and the poor one is more than ±3 degrees. Moreover, the error changes at any time, making it difficult to achieve precise temperature control. Therefore, there is an urgent need for a high-precision temperature control constant temperature controller (radio frequency external temperature measurement low-power module) to achieve precise temperature control.

The bottom shell 1 is fixed by the wall-mounted fixings 2 for easy installation. The front shell 6 and the bottom shell 1 are connected in a detachable manner to facilitate early assembly and later maintenance. Specifically, one end of the battery door 3 has a fixing plate and the other end has two misaligned protrusions. During installation, the misaligned protrusions are snapped onto and fixed to the bottom shell 1, and then the fixing plate is fixed to complete the installation of the battery door 3. The battery 4 is mounted on the battery door 3. The battery 4 is a round battery, so it can be embedded in the battery door 3, and the space utilization rate of the entire bottom shell 1 is improved.
