It is designed for two and four pipe fan coil units. BC106 has one universal input as external sensor or open/close contact input, five relay outputs 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 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 220 V AC and it has no internal fuse. External protection with max C 10 A circuit breaker required in all cases. Disconnect from power supply before separating f

Ordering Information Mounting Location The 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 a false signal for temperature control. CAUTION: Cut off the supply power at the circuit breaker or fuse before installation to avoid fire,

Mounting Instructions ROOM CONTROL PANEL Please follow below instructions during mounting. ROOM CONTROL PANEL 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...

• Key Lock Operations: Pressing both MODE and INCREASE keys, key lock digit displays on the panel. The panel is locked. When the panel is locked, press the MODE and INCREASE 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 Main Parameter Exit Main Value Value Main Key Parameter Increase...

Universal Input (Parameter P32 or via BACnet) - External Sensor for room (parameter P32 = 1) The device operates according to external temperature sensor value read from the universal input. - External Sensor (parameter P32 = 2) The device operates according to internal temperature sensor value. The temperature read from the universal input can be monitored from P36 and related BMS point. - Changeover sensor (parameter P32 = 3) If “Universal Input” value is selected as changeover, “dead zone” cannot be used. Changeover sensor only valid when “Fan Coil Type” is set to 2. When the water temperature...

Hysteresis (Parameter P40 or via BACnet) The output diagram of the valve according to the relation between TS and TR is given below. Fan/Valve Control Selection (Parameter P41 or via BACnet) In valve independent mode, the fan operates according to manual fan selection or automatic fan control. When valve is closed, the fan will continue to operate. In valve dependent mode, the fan will be closed when the valve is closed. If the valve is open, the fan will operate ROOM CONTROL PANEL according to manual fan selection or automatic fan control. Restore Factory Setting (Parameter P45 or via BACnet)...

Configuration Menu 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. As a property of Device Object, Device ID value is writable via BACnet between 0...
