Description

Technical Field

[0001] This utility model relates to the field of fan coil control technology, and in particular to a one-to-many wireless remote control fan coil temperature control device. Background Technology

[0002] Wireless pairing technology is essential for wireless one-to-one and one-to-many fan coil thermostats. While one-to-one pairing technology is mature, its effectiveness is limited. There are currently two main methods for one-to-many pairing. One method involves pre-pairing the thermostat (transmitter) with multiple actuators (receivers) at the factory before delivery to the customer's site. The other method is on-site pairing. On-site pairing is often a one-button method; for example, pressing the pairing button on the thermostat after powering on the actuator completes the pairing. While seemingly simple, this method can lead to pairing errors, especially when other actuators are powered off. In actual construction, multiple thermostats or actuators share one or more switches, and actuators that shouldn't be paired may still be connected if their power is not turned off. Another method involves powering on the thermostat and completing pairing on the actuator. However, if other thermostats are not turned off, uncontrolled actuators may pair with non-corresponding thermostats. If code conflicts occur and the codes start to fight each other, the on-site code matching operation will become chaotic.

[0003] Furthermore, current fan coil unit temperature control devices use a simple wireless technology where the controller transmits commands, and the actuator receives and executes them. However, in practice, signal attenuation occurs when the wireless distance between the two devices is relatively long or when there are many obstacles in between, leading to unstable signal reception by the actuator. Even slight changes in interference from obstacles can cause the actuator to lose signal. Additionally, the controller's signal transmission is not continuous; sometimes, after transmitting a command upon startup, it may not transmit a second command for an extended period. Current 315MHz and 433MHz single-channel wireless transmission technologies mostly involve a single command transmission, which the actuator then receives and executes. This situation can also lead to the actuator failing to receive a signal or experiencing signal reception failure.

[0004] Furthermore, the fan coil temperature control device is limited by unidirectional, single-channel communication. When the transmitter (temperature controller) loses power, or the signal attenuation is severe due to increased obstruction, the receiver cannot receive the signal. The actuator will then maintain and execute the previous signal command, continuing operation without stopping. For example, after the temperature controller loses power, the actuator continues to work without stopping. In the absence of a signal or with severe signal attenuation, the actuator continues to operate continuously, especially when the fan coil motor is running uncontrolled. This can lead to loss of control of the fan coil unit and, in severe cases, safety accidents.

[0005] Therefore, it is necessary to improve the current fan coil temperature control device. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a one-to-many wireless remote control fan coil temperature control device, which can effectively solve the problems of code conflict and mutual interference, inability to automatically cruise, and easy loss of control of existing fan coil temperature control devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-channel wireless remote-controlled fan coil temperature control device includes a temperature controller and multiple fan coils; the temperature controller has a transmitter; each of the multiple fan coils has a control box, and each control box is equipped with an actuator for controlling the operation of the fan coils. The actuator is connected to a receiver, and the receiver is wirelessly connected to the transmitter.

[0009] Preferably, the thermostat is installed on the exterior wall.

[0010] Preferably, the actuator is installed inside the external ceiling.

[0011] Preferably, the distance between the thermostat and each fan coil unit is within 40m.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0013] By setting up a temperature controller with a transmitter, wireless communication is achieved between the transmitter and the receivers of each fan coil unit, enabling unrestricted code matching for convenient on-site operation. It also features automatic cruise control to prevent signal attenuation or interference that could lead to unstable operation, actuator shutdown, or discrepancies between the actuator's operating status and commands. Furthermore, it can disconnect from the network and shut down, ensuring the actuator stops if it does not receive a transmitter command signal within a certain timeframe. This ensures controlled motor operation, mitigates safety risks, and provides users with peace of mind. Attached Figure Description

[0017] 20. Fan coil unit; 21. Control box

[0018] 211. Actuator; 212. Receiver Detailed Implementation

[0019] Please refer to Figure 1 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a thermostat 10 and multiple fan coil units 20.

[0020] The thermostat 10 has a transmitter 11, and its model is TMX900. Each of the multiple fan coil units 20 has a control box 21, and each control box 21 contains an actuator 211 for controlling the operation of the fan coil unit 20. The actuator 211 is connected to a receiver 212, which is wirelessly connected to the transmitter 11. In this embodiment, the thermostat 10 is installed on an external wall. The actuator 211 is installed inside the external ceiling, and its model is TR200. Furthermore, the distance between the thermostat 10 and each fan coil unit 20 is within 40 meters.

[0021] The working principle of this embodiment is described in detail below:

[0022] This product has the following functions:

[0023] 1. Unrestricted code matching function: The specific operation is as follows:

[0024] (1) Before matching the codes, please clear the codes of each executor 211.

[0025] (2) Confirm that the temperature controller 10 is in the off state (when the power is on, pressing the code key will have no effect).

[0026] (3) Press the pairing key of thermostat 10. The green light will stay on, indicating that thermostat 10 has entered the pairing state.

[0027] (4) Press and hold the pairing button of actuator 211 until the green light comes on, then release the button (do not press and hold for a long time). After releasing the button, the green light will flash 5 times automatically, indicating that the pairing with the temperature controller 10 is successful (note that if you press and hold for a long time, the code clearing operation will be performed).

[0028] (5) If the green light does not flash continuously, it indicates that the pairing has failed, the distance is too far, or the temperature controller 10 has not entered the pairing state. Pairing needs to be done again.

[0029] (6) In the same step (4), pair the actuators 211 of the next fan plate 20, and pair them one by one until all the actuators 211 that need to be paired are paired.

[0030] (7) After all the actuators 211 have successfully paired, press the pairing button on the temperature controller 10. The green light will turn off, indicating that the pairing state has been exited. The temperature controller 10 and the actuators 211 will then enter normal communication mode.

[0031] 2. Automatic cruise control function:

[0032] When the fan coil unit 20 is in operation, the temperature controller 10 continuously sends out operating mode and operating speed commands at regular intervals (every 20 seconds) to correct the operating mode and operating speed of the actuator 211, preventing the fan coil unit 10 from being in standby, freezing, or having incorrect operating mode and operating speed during operation, i.e., preventing foolproofing, preventing detachment, correcting deviations and preventing errors.

[0033] When actuator 211 is powered on, it will unconditionally execute any command received from the corresponding temperature controller 10. This prevents frequent automatic shutdowns of actuator 211 (fan coil) caused by occasional weak signals or short-term (within 180 seconds) interruptions in communication paths with multiple obstacles. The temperature controller 10 continuously transmits commands every 20 seconds to avoid malfunctions due to short-term packet loss, with minimal impact on the duty cycle.

[0034] Thermostat 10 transmits its current status every 20 seconds, including mode (two-way valve on / off status) and speed setting (fan high, medium, low, and automatic modes). Actuator 211 receives the signal; occasional packet loss and failure to receive a signal do not affect its operation.

[0035] 3. Offline shutdown function:

[0036] If the thermostat 10 is turned off, experiences a momentary power failure, or the communication network between the thermostat 10 and the actuator 211 is interrupted due to obstacles, and the receiver 212 connected to the actuator 211 does not receive any signal from the transmitter 11 of the thermostat 10 within 180 seconds, it will automatically shut down. This function specifies that the actuator 211 will shut down if there is no signal for a period of 180 seconds. If a signal appears within the 180-second period, the execution condition will be broken, and the actuator 211 will not continue to shut down, thus avoiding frequent product shutdowns.

[0037] The key design feature of this invention is: by incorporating a temperature controller with a transmitter, the controller wirelessly communicates with the receivers of each fan coil unit for unrestricted code matching, facilitating on-site operation. It also features automatic cruise control to prevent signal attenuation or interference that could lead to unstable operation, actuator shutdown, or discrepancies between the actuator's state and the command. Furthermore, it can disconnect from the network and shut down, ensuring the actuator stops if it does not receive a transmitter command signal within a certain timeframe. This ensures controlled motor operation, mitigates safety risks, and provides users with peace of mind.

[0038] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
