1. Produktoversigt
The CCT-28-X Wireless Hub Controller is an integral component of water underfloor heating systems. It serves as a central control unit, managing zone valves and boiler thermostats. This device controls the boiler and circulating pump based on user-defined temperature settings, opening or closing electric actuators to optimize comfort and energy efficiency.
When any room requires heating, the corresponding thermostat sends a signal to the hub. This activates the relevant actuator and illuminates its indicator. If no signal is received from a thermostat, the actuator turns off. When any thermostat sends a signal, the water pump (with power linkage) and boiler (without power linkage) are activated, and their respective indicators light up. Conversely, when all thermostats cease sending signals, the water pump and boiler are deactivated.
NOTE: The CCT-28-X itself does not have built-in Wi-Fi. A separate Wi-Fi enabled temperature controller is required to connect to the hub for remote control via Wi-Fi. Models like BOT-R6X-NR and BOT-R7X-NR are standalone controllers without a receiver.
2. Product Advantages
- Nem strømtilslutning: Users only need to reserve a main power supply at the manifold location before installation and connect a single three-wire cable to the thermostats. No professional wiring expertise is required.
- Enkel ledningsføring: Wires are connected easily by matching their colors.
- Nem vedligeholdelse: The clear and neat wiring simplifies post-installation maintenance.
- Boiler and Pump Protection: The hub controller features a time-delay function, activating the boiler and pump only when the water valve is fully open. It also closes the boiler when the desired temperature is reached, preventing unnecessary operation.
- Extended Boiler and Pump Lifespan: By operating the boiler and pump only at appropriate temperatures, the hub controller reduces their running time, thereby extending their operational life.

Sikkerhedsforanstaltninger
- Before installing, disassembling, cleaning, or maintaining the controller, ensure the main power supply is cut off. The fuse must be removed or the circuit breaker switched off.
- Read the instructions carefully and follow them strictly before installing.
- The controller should be installed by a professional engineering company with appropriate safety knowledge.
- All wire connections must comply with local and national standards.
Ledningsdiagram
The CCT-28-X hub can simultaneously control the temperature of up to 8 rooms. Each zone can be connected to one thermostat, and each thermostat can be connected to multiple zones.
- Strømforsyning: Connect the 220V AC power supply to the “N, L (INPUT)” terminals.
- Kedeltilslutning: Connect to a dry contact boiler using the “COM, NO” terminals (a small portion may connect to COM, NC).
- Vandpumpe: Connect the water pump to the “Pump” terminals.
- Aktuatorer: Connect normally closed actuators to the “ZONE 1-8” terminals.
- Termostatforbindelse: The thermostat communicates with each zone of the CCT-28-X via RF (Radio Frequency).
Compatible Actuators and Thermostats
The system supports various Beok thermostats and NC actuators. Examples inkluderer:
- NC-aktuator: RZ-AN230-NC
- Termostater: BOT-R6X-NR, BOT-R7B-X-NR, BOT-506X-NR, D07 NC Actuator
5. Parringsinstruktioner
This section details how to pair your thermostats with the CCT-28-X Wireless Hub Controller.
Pairing a Thermostat
- When LED11 (power indicator) is lit, long press the "RF Pairing Key" on the hub for 3 seconds until LED8 starts flashing.
- For BOT-R6X series thermostats: With the thermostat powered on, long press the 'down' button (▼) until the pairing icon appears (displayed for less than 1 second).
- For BOT-R7X series thermostats: With the thermostat turned off, long press the 'check' button (✓) until the pairing icon appears (displayed for less than 1 second).
- After successful pairing, LED8 will stop flashing and turn off. LED7 will then start flashing. Repeat step 2 or 3 with the next thermostat to pair it. If no further pairing is needed, wait 15 seconds until the LED light stops flashing.
- After all thermostats are paired, turn each thermostat off and then on again. The thermostat will now control the hub.
Switching Paired Terminals
To switch the terminals that need to be paired, press the "RF Pairing Key". The LED lights will jump from LED8 to LED1 in sequence. When the LED light corresponding to the desired terminal flashes, follow the pairing steps (step 2 or 3) to complete the pairing.
One Thermostat Controlling Multiple Terminals
To use one thermostat to pair all terminals, pair LED8 when LED8 starts flashing. Once LED8 is paired, LED7 will start flashing. Continue pairing with this thermostat until LED1 is paired.
Canceling Pairing
Long press the "RF Pairing Key" for 3 seconds until LED8 starts flashing. Short click the "RF Pairing Key" to switch the flashing LED light to the terminal you wish to unpair. Long press the "RF Pairing Key" again for 3 seconds until the LED light stops flashing, indicating that the pairing has been canceled.
6. App Control & Thermostat Features
The CCT-28-X hub communicates wirelessly with compatible thermostats via 433MHz RF. If your thermostat is Wi-Fi enabled, it can be connected to a mobile phone app (e.g., Tuya App), allowing you to control the thermostat remotely. The thermostat then sends signals to the CCT-28-X to manage the entire heating system.
Termostatfunktioner
- APP kontrol: Remote control via a smartphone application.
- Stemmestyring: Compatible with voice assistants for hands-free operation.
- Programmerbar: BOT-R7-NR and BOT-506X-NR models offer daily programming, while BOT-R6-NR supports weekly programming.
- Installationsmetoder: Can be placed on a table using a stand or securely wall-mounted with screws (no junction box required).
Thermostat Power Supply
Beok thermostats like BOT-R6X-WIFI-NR and BOT-R7X-WIFI-NR can be powered by either 3xAAA batteries or a Type-C USB cable (dual-port design).
7. Indikatorillustration
The CCT-28-X hub features several LED indicators to provide status feedback:
- LED1-LED8 (Thermostat Indicator Light): These LEDs correspond to each thermostat zone. The light illuminates when the thermostat starts heating and turns off when it stops. It flashes when the thermostat is in pairing mode.
- LED9 (Pump Indicator Light): This LED indicates the status of the circulation pump. It lights up when the pump is working and turns off when it stops.
- LED10 (Boiler Heating Indicator Light): This LED indicates the status of the boiler. It lights up when the boiler starts heating and turns off when it stops.
- LED11 (Power Indicator Light): This light is always on when the hub controller is powered on.
8. Power Outage Gendannelse
I tilfælde af en magt outage, the thermostat sends a signal to the controller every 30 minutes. The system will resume normal operation within 30 minutes after power is restored.
9. Fejlfinding
- Thermostat not connecting to Wi-Fi: Ensure your thermostat model is Wi-Fi enabled. The CCT-28-X hub itself does not have Wi-Fi; it relies on a Wi-Fi thermostat to connect to your home network. Make sure your Wi-Fi network is 2.4GHz, as most smart home devices are not compatible with 5GHz networks.
- System not responding after pairing: After pairing, ensure you turn the thermostat off and then on again to finalize the connection with the hub. Also, check that the LED indicators on the hub are behaving as expected (e.g., flashing during pairing, solid when active).
- No heating in a specific zone: Verify that the thermostat for that zone is correctly paired and sending signals. Check the corresponding LED on the hub (LED1-LED8) to see if it's lit when heating is requested. Ensure the actuator for that zone is functioning correctly.
- Boiler or pump not activating: Check LED9 (pump) and LED10 (boiler) indicators on the hub. Ensure that at least one thermostat is calling for heat. Remember the hub has a 5-minute delay for pump output.
- Wired thermostat connection: The CCT-28-X is designed for wireless communication with thermostats via RF. It does not directly support wired thermostat connections for zone control.
10. Brugertips
- For optimal performance and remote control, invest in a compatible Wi-Fi enabled thermostat that can connect to a smartphone app like Tuya.
- When pairing multiple thermostats, follow the steps carefully and ensure each thermostat is successfully paired before moving to the next.
- If you experience issues with pairing, try canceling the pairing for the specific terminal and re-attempting the process.
- Regularly check the LED indicators on the hub for quick status updates on your heating zones, pump, and boiler.
