ABB CI854AK01 3BSE030220R1 PROFIBUS-DP/V1 interface module CI854

Description

The central air-conditioning temperature controller CI854 is specially designed for controlling fan coil units, and is widely used in heating, cooling, ventilation and other HVAC controls. The fan speed can be controlled manually or automatically by adjusting the wind speed button to control the room temperature.

The central air-conditioning thermostat CI854 is divided into two types, one is mechanical and the other is liquid crystal. Nowadays, liquid crystal is generally used. One of its advantages is that it is equipped with a remote controller, which can realize remote control operation. The temperature controller is used to open and close the air conditioner, mainly to control the fan and solenoid valve. Its functions are mainly to adjust the air temperature, humidity, air flow speed, cleanliness, timing, etc.
2、 Installation method of CI854 central air-conditioning temperature controller
1. First, insert a flat screwdriver into the small card seat on the side of the temperature controller, gently pry off the bottom plate to separate the temperature controller panel from the bottom plate, and then fix the bottom plate with the screws you want to fix, and then snap the temperature controller panel onto the bottom plate.
2. Remove the cable between the LCD main board and the power drive board, remove the back cover of the LCD main board, and insert the power drive board into the embedded cassette.
3. Connect the drive board (power board) of the controller to the fan coil, electric valve (solenoid valve or air valve) and power line according to the drawing requirements. The wiring must be correct according to the electrical wiring diagram. Do not allow water, mud and other impurities to enter the thermostat, otherwise the device will be damaged.
3、 Operation method of central air-conditioning temperature controller
On/Off key: press the key to select the power on or power off status of the system.
M mode key: press the key to select the control mode of the system, cooling or heating. Refrigeration is to reduce the ambient temperature, and vice versa.
F Wind speed key: press the key to select the size of the output wind. The wind speed can be divided into three categories: low, medium and high. Different blades, from more to less, represent high, medium and low in turn.
▲ Adjust the temperature: you can set the temperature. If you need heating, the temperature you set should be higher than the indoor temperature, and the mode is heating. If it is lower than the indoor temperature, the mode is refrigeration.
