It is designed for two and four pipe fan coil units. BC106-4AED has one universal input that can be used as an external sensor or open/close contact input, three analog outputs, one relay output and one RS-485 port. It controls the fan coil unit depending on the internal room sensor or external return sensor temperature. Please, read this datasheet carefully. BC106-4AED thermostat is designed and manufactured in accordance with latest technological developments and safety. To avoid injury and property damage, safety warnings must be observed. Security Advice-Caution Assembly, maintenance, and repair must be done by authorized service. The power supply of the device is 24 V AC/DC and it has no internal fuse. External protection with max C 5 A circuit breaker required in all cases. Disconnect from power supply before separating front plate.

Mounting Location Thermostat is suggested to be installed indoors, a place with around 1.5m height above the floor so that it can measure the average room temperature. It should be away from direct sunlight, any cover or any heat source, to avoid false signals for temperature control. CAUTION: Cut off the supply power at the circuit breaker or fuse before installation to avoid fire, shock or death!

Please follow below instructions during mounting. Step 1: Take the thermostat out from the package. Get the datasheet inside the package. Step 2: Connect the wires properly according to the wiring diagram below. Step 3: Separate the front plate and the back plate, and then use screwdriver to fix the back plate into the electric box with 4 screws. Step 4: Attach the front plate to the back plate, making sure the pin plates on each side are well matched. Step 5: Compare it with the pictures after installation. Step 6: Power on the thermostat to work. Important Note 1: It is recommended to use the...

Cooling Valve Heating Valve Underfloor Heating Valve On/Off Mode Fan Speed Increase/ Decrease/ Key Key Key Up Down • Mode Selection: Press the “M" key to change the mode of the device. Active mode options are as follows. • Fan Selection: When the '"fy " key is pressed, fan speed can be changed as Stage 1, Stage 2, Stage 3, Stage 4, Stage 5, Auto. The fan can be selected as 1 stage, 3 stage or 5 stage via parameter P42. • Time Setting: After pressing the “M" key for 3 seconds, year digits flashes on the panel. “M" key is pressed once again, month digit flashes on the panel. “M" key is pressed...

• Key Lock Operation: Pressing both “M” and “” keys, key lock digit displays on the panel. The panel is locked. When the panel is locked, press the “M” and “” keys to unlock panel. “Key Lock” options can be changed via parameter P6. To lock two or more keys at the same time; sum the numbers of the keys. To lock mode key and on/off key, 1 (on/off) and 2 (mode) should be added and written 3 to parameter P6. To lock setpoint and fan speed, 4 (setpoint) and 8 (fan speed) should be added and written 12 to parameter P6. Configuration Configuration Menu Description When the device on or off position,...

- Windows contact/Energy saving-Off/On (NO Contact) (parameter P32 = 7) When this contact is opened, the device is in the "ON" position. When this condition is not met, the device shows “OPEN" on the panel and the outputs of the device are passive. - Heater Contact (NC Contact) (parameter P32 = 8) When this contact is opened, the electrical heater output is closed. The device shows “AL 04" on the panel. - Heater Contact (NO Contact) (parameter P32 = 9) When this contact is closed, the electrical heater output is closed. The device shows “AL 04" on the panel. The output diagram of the valve according...

Alarm Code will appear on the screen, during alarm. if one of the alarm conditions is met. Alarm Codes will appear on the screen alternately. If more than one alarm condition is met. - Onboard Sensor Alarm: If the internal temperature sensor fails, “AL 01" will appear on the screen and “Err" will be shown on the main digits. During the alarm, device outputs will be closed. If the “Universal Input" is selected to “External Sensor", the device continues normal operation. - External Sensor Alarm: If the “Universal Input" parameter is set to “External Temperature Sensor" and sensor is not connected...

BACnet Parameters According to BACnet standards, MSTP port configurations are as follows; -8 Data Bits, None Parity, 1 Stop Bit Baudrate : 9600, 19200, 38400, 76800. Default 76800 Note 1: The MAC address can be changed via configuration menu. Note 2: Device Instance Number (Device ID) is automatically calculated as below; For example: Mac: 13, Loop ID: 1 => Device ID = 856 * 1000 + 1 * 200+ 13 = 856213 When the MAC address is changed via configuration menu, the Device ID is automatically recalculated to avoid network ID conflict.
