This document describes the Hisense YJE-C01T(E) Central Controller, an optional control component designed for the centralized monitoring and control of air conditioning units. It allows users to manage air conditioners in groups or zones, query and display their operational status on an LCD screen, and set weekly or simple timers. The controller communicates with indoor units and wired controllers via an RS485 communication bus, using shielded twisted pairs with polarity (A+ B-). It can control units either centrally or locally via a wired controller, or centrally via a converter (purchased separately).
The manual emphasizes several safety precautions. Installation should be performed by a dealer or professional to prevent water leakage, electrical shock, or fire. It is crucial to follow the installation manual correctly. Users are warned not to splash water on the appliance or touch it with wet hands due to the risk of electric shock. Tampering with safety devices is prohibited. The main power supply must be cut off before opening the panel for repairs. Specific specification cables must be used and firmly connected to avoid overheating or fire. The appliance must be installed on a base capable of supporting its weight to prevent injury from falling. Electrical supply connection and leakage checks should be performed after installation.
The manual advises against installing the appliance in environments with oil, acid, alkali, sulfide gas (e.g., hot springs), flammable gas, high temperatures, flames, or high-frequency/wireless equipment, as these can cause interference, heat, fire, or damage. Moisture or water flooding can lead to electric shock or electronic parts failure. Spraying pesticides, paint, hair gel, or other toxic gases within 1 meter of the appliance is prohibited. If an Electric Leakage Break (ELB) or fuse trouble occurs, a local service shop should be consulted. Wiring work must adhere to the manual's instructions to prevent electric shock or fire. Objects should not be placed on the unit, and wires/electrical parts must be protected from rodents to prevent damage or fire. Wires must be firmly connected to avoid fire.
For installation, the indoor unit, outdoor unit, wired remote controller, or cables should be at least 3 meters away from high-frequency sources (e.g., medical appliances). Users should not trample or place objects on the products. The wired remote controller should be installed in a location where the average room temperature can be detected, not exposed to direct sunlight, and away from extremely hot or cold locations. Children should not play with the wired remote controller.
Upon receiving the product, it should be inspected for shipping damage, and claims should be filed immediately if any are found. All accessories listed must be included. The model number, electrical characteristics (power supply, voltage, frequency), and accessories should be verified for correctness. The manual explains the standard utilization of the unit, and any other use is not recommended. Local codes and regulations must be followed during installation. The company disclaims responsibility for unauthorized equipment changes.
The central controller offers two primary operation modes:
Before central control, group/zone settings must be configured.
If a higher-level centralized controller is used, group setting is required. The group number is only relevant for the centralized controller. All air conditioners in the network can be categorized into groups from 1 to 16. To set, hold "ADD. FUNC." for 3 seconds in shutdown state, then use "▲" or "▼" to select the group number, confirm with "ENTER," or cancel with "CANCEL."
A maximum of 16 zones can be set in a central control network, with up to 16 air conditioners per zone. To set, hold "ZONE" for 3 seconds until the zone number blinks. Use "▲" or "▼" to select the zone number, then "ENTER." Use "▲" or "▼" to select air conditioner addresses (1-16), confirm with "ENTER," or cancel with "CANCEL." Press "ZONE" again to set the next zone or exit.
When the central controller is started, the LCD displays the operating state of the air conditioners in the network sequentially if no other operations are performed.
The central controller unifies cooling, heating, drying, and air supply functions.
Turning ON/OFF:
Mode Setting: Press "MODE" to select the desired operation mode (Cooling, Dry, Fan Only, Heating) in ON state or OFF state with a timer set. The mode changes in sequence with each press.
Temperature Setting: Press "▲" or "▼" to set the desired temperature. The temperature setting blinks on the LCD, indicating setting mode. Each press of "▲" increases temperature by 1°C; each press of "▼" decreases it by 1°C. Setting is confirmed 3 seconds after the value stops blinking.
Fan Speed Setting: Press "SPEED" to select fan speed (Low, Medium, High, Auto) in ON state or OFF state with a timer set. The fan speed changes in sequence with each press. In "DRY" mode, fan speed is automatically set to "AUTO," and the "FAN" button is ineffective.
SWING Setting: Press "SWING" to select the swing mode (Up/Down SWING, Left/Right SWING, Up/Down/Left/Right SWING, No display/Nothing) in ON state or OFF state with a timer set. This setting is only effective for units with a swing function and specific models.
The clock must be set when using the central controller for the first time or after a power loss.
Hold "TIMER/CLOCK" for 3 seconds in complete shutoff state to enter clock correction. Adjust settings using the same method as clock setting. After adjustment, press "ENTER."
This function prevents accidental operation by children or others.
Allows setting ON/OFF times for seven days a week, with up to four groups of settings assignable to any day. The resolution is 1 minute, and the signal is effective within 1 minute.
Wipe the LCD and body of the wired controller with a dry cloth. For stubborn dirt, use a cloth soaked in neutral detergent diluted with water, squeezed tightly, then wipe with a dry cloth. Do not use thinner, organic solvents, or strong acid.
If the air conditioner malfunctions, an error code will display on the LCD. Note the error code and contact After-sales Service. Consult the dealer for more information.
Installation must follow these instructions and be performed by professionals.
The packaging box should contain:
Selecting Location: Choose the installation location based on the "Important Notice" guidelines.
Removing Upper Cover: Insert a screwdriver into the designated position and gently rotate to remove the upper cover.
Connecting the Central Controller:
The default baud rate code is 00, supporting communication up to 1000m. The baud rate may need to be changed for different central control systems to ensure transmission rate.
Hold "ADD.FUNC." and "ON/OFF" for 3 seconds. Buzzer beeps 4 times, entering self-checking state. Use "▲" to select series number 3, then "ENTER." When "boot" blinks on the LCD, press "ENTER" to reset the system. All system settings (except dial switches) are restored to factory settings.
Align the upper cover with the corner buckles of the lower cover and press until it snaps into place. Remove the protective sticker after installation.
