1. Product Summary
The Beok Zone Heating System Controller (connection center box) is designed for floor heating systems. It receives control signals from room thermostats to operate the corresponding floor heating circuit actuators. This unit also features power linkage control modules to manage external components such as water pumps (or mixing units, main valves) and boilers (or heat pumps).
Product Features:
- Supports up to 8-way floor heating thermostats and actuators.
- Equipped with an AC 220V power supply, it can directly power thermostats and external water pumps, simplifying wiring.
- Includes a special delay start function for linkage control, adjustable to suit various electric actuators with long opening times.
- Each control circuit, water pump, and boiler linkage features an indicator light for clear operational status.
- Offers multiple installation options for diverse applications.
2. Safety Information and Important Notes
WARNING: This product operates with high voltage. Improper installation, use, or maintenance can lead to electric shock or other hazards. Always follow safety guidelines.
- Installation and maintenance must be performed by qualified professionals in accordance with all relevant regulations and accident prevention guidelines. Unauthorized dismantling or repair is prohibited.
- Always disconnect the power supply before removing the box cover, wiring, or adjusting any settings to prevent equipment damage or electric shock.
- This product is designed for normally closed (NC) actuators. Using normally open (NO) actuators may cause abnormal operation.
- The buttons on the circuit board are for factory internal testing only and should not be operated by users to avoid accidents.
- Ensure that the load of each interface does not exceed the specified technical parameters.
3. Setup and Installation
3.1. Product Dimensions and Mounting
The overall dimensions of the controller are 240mm (Length) x 110mm (Width) x 42mm (Thickness).
The unit can be mounted using screws through the reserved fixing holes on the bottom box or directly onto an electrician's guide rail using the back card slot. The bottom box has several connection ports that can be opened with a slotted screwdriver as needed.
3.2. Wiring Connection Overview
The following diagram illustrates a typical setup for a floor heating system. Connect all components according to your specific system configuration.
3.3. Detailed Wiring Instructions
Refer to the internal wiring diagram for precise connections:
- Power Supply (L, N): Connect the live line (L) and neutral line (N) of the AC 220V power supply to the respective terminals.
- Thermostat Connections (L, N, Control): Connect the L, N, and control lines from your room thermostats. The control terminal of the thermostat should be normally open.
- Actuator Connections (V1-V8): Connect the normally closed (NC) electric actuators to the corresponding V1-V8 terminals. If connecting multiple actuators to a single zone, wire them in parallel.
- Active Linkage Contact (L1, N1, Pump): Used to control external equipment like a water pump or valve. It provides AC 220V directly to drive the equipment. Connect L1 and N1 to the live and neutral lines of the external water pump.
- No Power Linkage Contact (NO, NC, COM, Boiler): Used to control boilers or heat pumps. It provides normally open (NO) and normally closed (NC) contacts, sharing a common terminal (COM).
- Earth Terminal: Connect the ground wire of the power supply and any external equipment requiring grounding.
- Timing Switch Pull Code: Used for delay control settings.
- Fuse: The unit is protected by a 15A fuse.
3.4. Actuator Connection Details
The controller supports both Normally Closed (NC) and Normally Open (NO) actuators. Ensure you connect the correct type to the designated terminals.
Each port (V1-V8) on the controller can manage multiple actuators connected in parallel. For example, a single port can control up to 4 NC actuators.
4. Operating Instructions
4.1. Working Principle
When a temperature controller sends an input signal, the corresponding actuator turns on, and its indicator light illuminates. When the temperature controller sends no signal, the actuator turns off, and its indicator light extinguishes.
Upon receiving a signal from a temperature controller, after a preset delay time, the linkage output for the water pump (if power linkage is used) and the boiler (if no power linkage is used) activates, and their respective indicator lights illuminate. When all temperature controllers cease sending signals, the linkage output for the water pump and boiler turns off, and their indicator lights extinguish.
4.2. LED Status Indicators
The CCT-10 Link Box features several LED indicators to show various operational states:
On the Product Shell:
- V1-V8 Indicators: Correspond to the 8 temperature control circuits (left to right). Light on indicates the circuit is on; light off indicates the circuit is off.
- PUMP and BOILER Indicators: Correspond to the active output for the water pump and the passive output for the boiler, respectively. Light on indicates equipment is on; light off indicates equipment is off.
On the Internal Circuit Board:
- LED1: Indicates power status. Light on means power input is present.
- LED2: Indicates working state. Flickering means normal operation; no light or constant light indicates a fault.
- LED3: Pilot indicator.
- LED4: Pump indicator.
- LED5-LED12: V1-V8 indicators.
4.3. Delay Control Setting
Electric actuators typically take 80-180 seconds to fully open. To ensure proper operation of the water pump and boiler, the CCT-10 link-box includes a linkage control with a delay start function. You can adjust the delay time using the pull codes to suit different actuators.
| Pull Code | P1 Position | P2 Position | Delay Time |
|---|---|---|---|
| Combination code 1 (Factory settings) | ON | ON | 120S |
| Combination code 2 | ON | OFF | 60S |
| Combination code 3 | OFF | ON | 45S |
| Combination code 4 | OFF | OFF | 30S |
5. Maintenance
The Beok Zone Heating System Controller is designed for reliable operation with minimal maintenance. Keep the unit clean and free from dust. Do not use abrasive cleaners or solvents. Ensure proper ventilation around the unit. Any internal servicing should only be performed by qualified personnel.
6. Troubleshooting
If you encounter issues, refer to the LED status indicators (Section 4.2) for initial diagnosis.
- No Power (LED1 Off): Check the main power supply and connections to the L and N terminals. Verify the fuse (15A).
- System Fault (LED2 Solid or Off, not Flickering): This indicates a potential internal fault. Ensure all connections are secure and within specifications. If the issue persists, professional assistance may be required.
- Actuator Not Responding: Check the thermostat signal. Verify the actuator wiring (NC type required). Ensure the actuator is receiving power.
- Water Pump/Boiler Not Activating: Check the thermostat signal. Verify the linkage wiring. Ensure the delay time setting is appropriate (Section 4.3).
For complex issues, consult a qualified technician.
